Terms of Service

Last updated: 17 May 2026 · Operated by Neosphere Inc., a Delaware C-Corporation

These Terms of Service (the “Terms”) govern your access to and use of the D6N marketplace, the d6n.ai website, the D6N MCP tools, the D6N CLI and SDKs, and all related services (collectively, the “Service”). The Service is operated by Neosphere Inc., a Delaware C-Corporation (“D6N,” “we,” “us,” or “our”). By accessing, browsing, listing on, buying through, or otherwise using the Service — whether as a human user, as an AI agent acting on a human user’s behalf, or through any client, CLI, or API — you agree to these Terms. If you do not agree, you must stop using the Service.

Read this first. D6N is a marketplace. We connect buyers and sellers, take payment on the seller’s behalf, and operate the catalog, payment rails, returns/refunds, and service-level commitments. D6N does not manufacture, originate, host, deliver, or warrant the underlying goods or data that sellers list. Section 17 and Section 19 explain the limits of our role and liability.

1. The Service

D6N is a categorized listing marketplace for agent commerce. Sellers list goods and services in one of the following listing categories:

Data — datasets, indices, training corpora, structured information, files, and other digital information assets.
Physical Goods — tangible items that must be shipped to the buyer.

Buyers may be human users browsing the Service directly, AI agents acting on behalf of a human user, or registered organizational accounts. Buyers transact using a saved payment method on file with D6N, using the Machine Payments Protocol (“MPP”) with a Stripe Single-Payment Token (“SPT”), or via any other payment rail D6N supports from time to time.

D6N reserves the right to add, remove, or modify listing categories, payment rails, and platform features at any time.

2. Eligibility

You may use the Service only if you:

Are at least 18 years of age, or the age of majority in your jurisdiction, whichever is higher;
Have the legal capacity to enter into binding contracts;
Are not located in, ordinarily resident in, or organized under the laws of a jurisdiction subject to comprehensive U.S. sanctions or any equivalent restriction; and
Are not prohibited from using Stripe or any other payment processor that D6N relies on to settle your transactions.

Sellers must additionally be eligible to receive payouts via Stripe Connect in a Stripe-supported country and must successfully complete Stripe’s Know-Your-Customer and Know-Your-Business onboarding.

The Service is not intended for children under 18. We do not knowingly permit anyone under 18 to create an account, list, buy, or otherwise transact on the Service.

3. Accounts and Credentials

You are responsible for maintaining the confidentiality of your D6N account credentials, any API keys, MCP installation tokens, agent session tokens, and payment credentials issued by or stored on your account. You are responsible for all activity that occurs under your account, including activity performed by any AI agent you authorize. You agree to:

Provide accurate registration information and keep it current;
Promptly notify us at support@d6n.ai of any unauthorized use or suspected compromise of your credentials;
Not share, resell, or sublicense your credentials except to AI agents and tools you have authorized to act on your behalf.

4. Geographic Availability

D6N is offered worldwide, subject to local law. Payments are processed via Stripe and are therefore subject to Stripe’s supported countries, currencies, and regulatory requirements. Sellers must be able to receive payouts in a Stripe-supported jurisdiction. Some categories (such as Physical Goods that cross customs borders, or regulated services) may be further restricted by the seller, by law, or by D6N. We may, at our sole discretion, suspend or limit access from any jurisdiction at any time.

5. Buyer Terms

5.1 Binding purchases

Initiating a purchase on the Service — whether by clicking a buy control, calling the buy_d6n_listing MCP tool, completing an MPP challenge with a valid Payment-Credential, or by any equivalent action — is an offer to buy that becomes binding when D6N or the seller accepts it (for example, when payment is captured, when an order moves to paid, or, for bookings, when the seller transitions the order to accepted). Once an order is binding, you owe the listed price plus any applicable taxes, fees, shipping, and service charges shown to you at checkout.

5.2 AI agent buyers and the authorized-agent doctrine

You may authorize one or more AI agents (whether operated by you, by a third-party agent platform, or by D6N) to act on your behalf on the Service. You agree that:

Any purchase, bid, booking, or other transaction initiated by an AI agent using your D6N account, your saved payment method, your Payment-Credential, or any other credential that authenticates as you is an act of your own authorized agent and is fully and irrevocably binding on you, regardless of whether the agent acted in error, exceeded the scope of your instructions, misunderstood your intent, hallucinated a need, or selected the wrong listing;
You are responsible for all charges, fulfillment commitments, no-show penalties, taxes, fees, and other obligations arising from such transactions;
Any remedy for an agent-error transaction is the same as the remedy you would have if you had made the purchase yourself — that is, the refund, return, and SLA rules in Sections 9 and 12 of these Terms;
You will configure appropriate spend caps, scopes, and other controls (where the Service makes them available) before authorizing an agent;
You will not authorize an agent to make purchases on behalf of any other person without that person’s authority and a lawful basis.

If you believe your credentials have been used without your authority (for example, a stolen Payment-Credential or compromised account), notify support@d6n.ai immediately and treat it as a security incident rather than an agent-error transaction.

5.3 Buyer obligations

Provide accurate shipping, delivery, contact, and booking information;
For Physical Goods, accept delivery within a reasonable time and inspect the item promptly;
For Data listings, use the purchased asset only within the scope and license terms disclosed by the seller;
Not initiate chargebacks for transactions that should instead be handled through the return, refund, or order-support process in Section 12.

6. Seller Terms

6.1 Stripe Connect onboarding

To receive payouts on the Service, you must complete Stripe Connect onboarding, including providing identification, tax, and bank-account details directly to Stripe. D6N does not custody your funds and does not hold or have access to your bank account. Stripe holds settled funds in your Stripe Connected Account until they are paid out under the schedule we configure. D6N may suspend, hold, or reverse payouts from your Stripe Connected Account where required by law, by Stripe, or by these Terms (for example, during a return, refund, chargeback review, or SLA-driven refund).

6.2 Listing accuracy and lawfulness

You represent and warrant that every listing you publish is accurate, lawful, current, and that you have all rights necessary to sell it. Listings must not be misleading, must use the correct category and required schema fields, and must clearly disclose any material restriction (region locks, license scope, sub-licensing limits, etc.). You are solely responsible for the goods, content, or rights that you list, and for honoring every term you publish.

6.3 Fulfillment and service-level commitments

By listing on D6N you accept the following baseline operational commitments. These are enforced automatically by D6N’s order system; failure to meet them may cause the order to auto-refund and may reduce your standing on the platform.

Category	Baseline commitment	If you miss it
Physical Goods	Maintain complete D6N shipping details and buy any needed outbound shipping label after `paid`; hand off to the carrier (tracking active) within 48 hours after the order becomes `paid`.	Order is cancelled and refunded or authorization-cancelled for the buyer; you do not receive payout.
Physical Goods (returns)	After an eligible return request, the buyer obtains a D6N return label and must ship the return using the provided label.	Order may be marked returned and refunded to the buyer according to the return state and carrier tracking.
Data	Provision the asset to the buyer immediately upon successful payment (digital fast-path).	Buyer is entitled to a full refund.

Categories may have additional category-specific rules. You agree to follow the rules disclosed at listing creation for the category in which you publish.

6.4 Seller representations

For each listing, you represent and warrant that: (a) you own the listed asset or are authorized to sell it; (b) the listing does not infringe any third-party intellectual property, privacy, contractual, or publicity right; (c) the listing complies with all applicable laws, regulations, sanctions, and platform restrictions; (d) you will deliver what you promised in the listing; (e) for regulated categories (alcohol, financial services, healthcare, professional services, etc.), you hold every license, registration, or authorization required to operate.

7. Platform Fees and Taxes

7.1 Platform fee

D6N charges a platform fee on each completed transaction. The fee may include a percentage of the listing price (up to forty percent (40%) of the listing price) plus pass-through of payment-processor costs. The exact applicable fee for any given listing is shown to the seller at listing creation, may differ by category, and may be updated by D6N from time to time with notice. The buyer always sees the final amount payable, inclusive of fees and applicable taxes, before purchase.

7.2 Payment-processor costs

Stripe and any other payment processor that processes your transaction will assess its own fees. Those fees are passed through and reflected in seller payouts.

7.3 Taxes

Each user is responsible for determining, collecting, reporting, and remitting any tax that applies to its activity on the Service, including income tax, withholding tax, sales / use tax, VAT, GST, hotel / occupancy tax, and digital-services tax. Where D6N is legally required to act as a marketplace facilitator and collect tax on a seller’s behalf (for example, in certain U.S. states), D6N may collect and remit that tax and reflect it in the order; this does not change the seller’s underlying tax obligations and does not constitute tax advice.

8. Order Lifecycle and SLAs

Every D6N order moves through a defined lifecycle: created → paid and then a category-specific fulfillment path that ends in completed, returned, or cancelled. For physical goods, paid means the buyer payment is authorized and the item is reserved; D6N captures that payment when the checkout-funded outbound label is generated. Stale unpaid checkout attempts may expire before payment. Return progress is tracked as order state; refunds are payment actions attached to selected order transitions. Service-level deadlines (the “SLAs”) are enforced automatically by D6N. SLAs include, without limitation, the following auto-transitions:

paid → cancelled after 48 hours if outbound fulfillment has not reached carrier scan;
label_generated → cancelled on that same 48-hour deadline if the parcel has not been handed off to the carrier;
requested → cancelled after 5 minutes if a booking seller has not accepted the booking;
delivered → completed automatically when the 14-day return / refund window expires without a return being requested;
accepted → completed automatically when the booked service window ends.

You acknowledge that these automatic transitions are a feature of the Service, not an error, and that they may cause your order to refund, complete, cancel, or expire without further notice.

9. Refunds, Returns, Cancellations

9.1 Physical Goods

Buyers may request a return for any reason within fourteen (14) days after delivery (the “return window”). D6N generates the return shipping label for eligible returns. When the buyer ships the return using the provided label, D6N may refund the original payment in full according to the order state and carrier tracking. If the buyer fails to ship the returned item within fourteen (14) days after receiving the return label, the order may be treated as completed and no refund is issued.

If a parcel is lost in transit, delivery fails, or the parcel is returned to the seller as undeliverable, D6N will refund the buyer once the carrier confirms the failure.

9.2 Data

Data listings are final sale once the asset has been provisioned to the buyer. A refund is available only where (a) the asset was never delivered, (b) the delivered asset is materially different from what the listing described, or (c) the asset cannot be opened, decrypted, or used for a technical reason solely attributable to the seller. Contact support for data-order issues.

9.3 SLA-driven and seller-failure refunds

Where a seller cancels an unshipped order, or an order is automatically cancelled or returned under Section 8 because the seller missed an SLA, the buyer receives a full refund and the seller receives no payout. If an outbound shipping label was already generated, D6N may deduct the actual carrier cost from the seller’s balance until the carrier confirms that the unused label was refunded. A confirmed carrier refund releases that deduction; use of the label or carrier rejection of the refund leaves the deduction in place. D6N may, in its discretion, charge re-listing fees, restock fees, or assess platform fees against repeated SLA failures.

9.4 Chargebacks

Buyers agree to use the return, refund, or order-support process in Section 12 before initiating a chargeback. Unjustified chargebacks may result in account suspension. Where a buyer initiates a chargeback, D6N may participate in or contest the chargeback on the seller’s behalf and may debit chargeback amounts and associated fees from the seller’s Connected Account.

10. Prohibited Listings and Acceptable Use

You may not list, sell, or solicit through the Service any of the following:

Anything illegal in the buyer’s or seller’s jurisdiction;
Weapons, firearms, ammunition, explosives, regulated chemicals, or items designed to cause physical harm;
Controlled substances, prescription medications, or drug paraphernalia;
Counterfeit, stolen, or pirated goods, or anything that infringes a third-party intellectual property, trade-secret, or publicity right;
Datasets containing personally identifiable information collected without a lawful basis, or any data scraped in violation of source-platform terms or applicable law;
Child sexual abuse material or any content that sexualizes minors;
Hate-targeted content, incitement to violence, terrorist propaganda or recruitment material;
Malware, exploits, ransomware, credential dumps, illicit-access services, fraud kits, or services designed to compromise systems or accounts;
Live animals, human remains, organs, blood, or other body parts;
Securities, investment contracts, currency, or any other instrument whose sale is regulated and not authorized through D6N;
Multi-level marketing schemes, lotteries, or other prohibited promotions;
Services that impersonate a real person without their authority, or that exist to facilitate fraud, doxxing, harassment, or election manipulation;
Sexually explicit material, escort or sexual services, and any sexual contact, in any category;
Anything D6N flags as creating an unreasonable risk to buyers, the platform, payment partners, or third parties.

In addition, you agree not to: (a) scrape, crawl, or harvest the Service or the catalog except via documented APIs and within published rate limits; (b) reverse-engineer the Service or any model that powers it; (c) probe, attack, or attempt to bypass the Service’s security, authentication, rate-limiting, or moderation systems; (d) game the SLA system or manipulate the listing schema; (e) use the Service to send spam, unsolicited bulk communications, or to operate a botnet; (f) infringe the rights of, defraud, or harass any other user.

11. Moderation and Reporting

D6N may, but is not obligated to, review listings, orders, communications, and other activity on the Service. We may, at any time and without prior notice: remove or restrict any listing; cancel any order; freeze payouts; suspend or terminate any account; report unlawful activity to law enforcement; and disclose information as required by law. Report problematic listings or activity to support@d6n.ai.

12. Order Support, Returns, and Chargebacks

12.1 First, talk to the seller (or the buyer)

You agree to attempt to resolve order-level issues (delivery, condition, no-show, scope mismatch, etc.) directly through the messaging channel D6N provides on the order, before escalating to D6N support or to a payment-network chargeback.

12.2 Returns and order support

Physical Goods use the return path in Section 9.1. Data purchases are final once provisioned and are not refundable except as stated in Section 9.2. For other order issues, D6N may review support information from either party and apply the order lifecycle, SLA, refund, and chargeback rules in these Terms.

12.3 D6N’s role

D6N is a marketplace operator and not a party to the underlying transaction between the buyer and the seller. D6N’s order-support actions settle the marketplace flow only; they do not constitute legal adjudication, and they do not preclude either party from pursuing other lawful remedies, subject to Section 16.

13. Intellectual Property

13.1 D6N IP

The Service, including the D6N marketplace, the categorization model, MCP tools, CLI, SDKs, website, documentation, software, design, and all other materials produced by D6N, is owned by Neosphere Inc. or its licensors and is protected by intellectual property and other applicable laws. Nothing in these Terms grants you any right in D6N’s intellectual property except the limited right to use the Service as described.

13.2 Your content; license to D6N

You retain ownership of the content you submit to the Service, including listing copy, descriptions, photos, files, and any data uploaded as part of a Data listing (“Your Content”). You grant D6N a non-exclusive, worldwide, royalty-free, sublicensable license to host, store, reproduce, transform, transcode, index, embed, display, distribute, and otherwise use Your Content to operate, maintain, market, secure, and improve the Service, to fulfill orders, to enforce these Terms, and to train and improve D6N’s categorization model and other internal systems. For published listings, this license is irrevocable for the period the listing is published and survives termination to the extent necessary to honor existing orders, comply with law, and maintain archival records.

13.3 DMCA / IP infringement

D6N respects intellectual property rights and operates a notice-and-takedown process under the Digital Millennium Copyright Act and analogous laws. To submit a notice, send to support@d6n.ai a written communication that includes: (i) identification of the work claimed to have been infringed; (ii) identification of the allegedly infringing listing or material, with enough detail to locate it; (iii) your contact information; (iv) a statement that you have a good-faith belief that the use is not authorized; (v) a statement, under penalty of perjury, that the information is accurate and you are authorized to act; and (vi) a physical or electronic signature.

14. Privacy

D6N’s collection and use of personal information is governed by our Privacy Policy, which is incorporated into these Terms by reference. By using the Service you acknowledge that data necessary to complete a transaction, such as shipping address for Physical Goods, will be shared with the relevant counterparty.

15. Suspension and Termination

D6N may suspend or terminate your access to the Service, any account, any listing, or any order, at any time, with or without notice, if we believe you have violated these Terms, applicable law, the rules of Stripe or another payment partner, or that your activity creates a risk to the Service, to buyers, to sellers, to payment partners, or to third parties. You may stop using the Service and close your account at any time by contacting support@d6n.ai; closure will not extinguish obligations on open orders, pending refunds, taxes, fees, indemnities, or other amounts owed.

On termination, your right to use the Service ends. Sections that by their nature should survive (including without limitation Sections 5.2, 6.4, 7, 9, 13, 14, 17, 18, 19, 20, 21, and 22) survive termination.

16. Marketplace Disclaimer (Important)

D6N is a marketplace and not a manufacturer, distributor, retailer, importer of record, common carrier, broker, fiduciary, licensed financial institution, licensed insurer, or registered investment adviser. D6N does not pre-screen, inspect, certify, or guarantee any listed good, software, service, or data asset. The seller is the counterparty in every underlying transaction; the seller bears the obligations associated with the listed item.

17. Disclaimers

THE SERVICE AND ALL LISTINGS, MODELS, OUTPUTS, DATA, RECOMMENDATIONS, SEARCH RESULTS, AND CATEGORIZATIONS PROVIDED THROUGH IT ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE. D6N DOES NOT WARRANT THE ACCURACY, COMPLETENESS, LEGALITY, OR FITNESS FOR PURPOSE OF ANY LISTING, ANY SELLER REPRESENTATION, OR ANY OUTPUT OF D6N’S CATEGORIZATION OR SEARCH MODELS.

Where applicable law does not allow exclusion of certain implied warranties, the duration of any such warranty is limited to the minimum period permitted by law.

18. Indemnification

You will defend, indemnify, and hold harmless Neosphere Inc., its affiliates, and its and their officers, directors, employees, contractors, and agents from and against any claim, demand, loss, liability, damage, cost, or expense (including reasonable attorneys’ fees) arising out of or relating to: (a) your use of the Service; (b) any listing you publish; (c) any order you place or fulfill; (d) any act or omission of an AI agent you authorized; (e) your breach of these Terms or of any applicable law; or (f) any infringement or violation of any third-party right by you or Your Content.

19. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, NEITHER D6N NOR NEOSPHERE INC. NOR ITS LICENSORS WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, BUSINESS, GOODWILL, USE, OR DATA, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE FULLEST EXTENT PERMITTED BY LAW, D6N’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS (US$100) OR (B) THE TOTAL PLATFORM FEES PAID BY YOU TO D6N IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

Nothing in these Terms limits liability that cannot be limited under applicable law (for example, for fraud, gross negligence, willful misconduct, or death or personal injury caused by negligence).

20. Dispute Resolution; Arbitration; Class-Action Waiver

20.1 Informal resolution

Before filing any formal legal claim, you agree to first contact us at support@d6n.ai and to attempt to resolve the dispute informally for at least thirty (30) days.

20.2 Binding individual arbitration

If informal resolution fails, you and D6N agree that any dispute, claim, or controversy arising out of or relating to the Service or these Terms will be resolved by binding individual arbitration administered by JAMS under its Streamlined Arbitration Rules and Procedures then in effect. The seat of arbitration will be Wilmington, Delaware; the language of arbitration will be English. The arbitrator’s award will be final and binding and may be entered as a judgment in any court of competent jurisdiction.

20.3 Class-action and jury-trial waiver

YOU AND D6N AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. YOU AND D6N EACH WAIVE THE RIGHT TO A TRIAL BY JURY.

20.4 Opt-out

You may opt out of this arbitration agreement by sending written notice to support@d6n.ai within thirty (30) days of first accepting these Terms, stating your name, account email, and that you opt out.

20.5 Small claims

Either party may instead bring an individual action in small-claims court for any dispute within that court’s jurisdictional limits.

21. Governing Law

These Terms are governed by the laws of the State of Delaware, U.S.A., without regard to its conflict-of-laws principles. Subject to Section 20, you consent to the exclusive personal jurisdiction and venue of the state and federal courts located in New Castle County, Delaware. If you are a consumer in the European Economic Area, the United Kingdom, or another jurisdiction whose mandatory consumer-protection laws apply, nothing in these Terms deprives you of the protections those laws provide.

22. Changes to These Terms

We may update these Terms from time to time. Updates take effect when posted; we will update the “Last updated” date above and, for material changes, will give at least thirty (30) days’ notice via the Service or by email where required by law. Your continued use of the Service after a change becomes effective constitutes acceptance.

23. Notices and Contact

You consent to receive electronic communications from D6N, and you agree that those communications satisfy any legal requirement that such communications be in writing. Notices to D6N must be sent to:

Neosphere Inc. · D6N

Contact: support@d6n.ai

Web: d6n.ai

24. Miscellaneous

These Terms (together with the Privacy Policy and any category-specific addenda referenced at listing) are the entire agreement between you and D6N regarding the Service and supersede all prior agreements on the same subject.
If any provision is held invalid or unenforceable, the remainder remains in full force, and the invalid provision will be reformed only to the minimum extent necessary.
Failure to enforce a provision is not a waiver of it.
D6N may assign these Terms in whole or in part, including in connection with a merger, acquisition, financing, or sale of assets. You may not assign these Terms without D6N’s prior written consent.
Neither party is liable for any failure or delay caused by events beyond its reasonable control, including acts of God, war, terrorism, civil unrest, pandemic, government action, network or payment-rail outage, or carrier failure.
Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between you and D6N.
