These Terms of Service (“Terms”) govern your use of x402Fi at x402fi.dev, including its website, payment gateway, facilitator, discovery feed and related software (together, the “Service”). The Service is operated by Only Buy Bitcoin LLC (“we”, “us”). By using the Service, connecting a wallet, signing in, listing a service or paying for one, you agree to these Terms. If you do not agree, do not use the Service.
1. What x402Fi is
x402Fi is software that helps sellers charge for API calls and on-chain products using the open x402 payment standard, with payments in USDG on Robinhood Chain. Buyers, which may be people or automated agents, sign a payment authorization in their own wallet. x402Fi checks that authorization, forwards the request to the seller and submits the payment to the blockchain.
x402Fi is non-custodial. Payments move directly from the buyer’s wallet to the seller’s wallet (or to a seller’s smart contract) under the buyer’s own signed authorization. We never hold, control or transmit your funds, and we cannot reverse, refund or redirect a payment once it is settled on-chain. We are not a bank, money transmitter, payment processor, exchange, broker or custodian. See the Disclaimer.
2. Eligibility
- You must be at least 18 years old and able to form a binding contract.
- You may not use the Service if you are located in, or a national or resident of, a country or region subject to comprehensive sanctions, or if you are on any sanctions list maintained by the United States, the United Nations, the European Union or the United Kingdom.
- If you use the Service for an organization, you confirm you are authorized to bind it to these Terms.
- You are responsible for complying with the laws that apply to you, including any rules on accepting or paying with stablecoins.
3. Wallets and sign-in
You access the Service with a self-custodied crypto wallet. You are solely responsible for your wallet, its keys and everything signed with it. Signing in is a free message signature that proves control of an address; it does not move funds. Anyone who controls your wallet can act as you on the Service.
4. Sellers
If you list a service, you agree that:
- You own or have the right to sell access to the API, data, content or on-chain product you list, and doing so does not infringe anyone’s rights or break any law or third-party terms.
- Your listing is accurate, including its description, price and payout wallet, and you keep it accurate.
- You are solely responsible for the service you provide, its uptime, its responses and any support, refunds or disputes with buyers.
- You are responsible for your own taxes, accounting and regulatory obligations arising from payments you receive.
- You will protect your upstream secret header and reject calls that do not carry it if you want your paywall enforced.
- We may review, pause, hide or remove any listing at any time, with or without notice, including for suspected abuse, fraud, legal risk or a breach of these Terms.
5. Buyers
- Before you sign, the Service shows the exact price, token, network and recipient. A signed authorization lets that exact amount move once, to that recipient, before it expires.
- For API listings, the payment is settled only after the seller’s service responds successfully. If the service fails or times out, the authorization is not used and you are not charged.
- For on-chain listings (for example, name registration), payment and delivery happen in a single transaction: either both succeed or neither does.
- Settled payments are final. Any request for a refund or remedy is between you and the seller.
6. Fees
Listing a service is free and x402Fi currently takes no percentage of payments. x402Fi pays the network fee (gas) to settle payments; to keep this sustainable, paid calls have a minimum price of $0.01. The only optional paid step offered in the listing flow is registering an x402 Identity name, which is a separate third-party service with its own price, paid on Ethereum. We may introduce or change fees for future use; changes will not apply to payments already made.
7. Identity names and Verified Payee
x402 Identity names are ENS names issued by a third-party registrar. Registering, renewing and managing a name is subject to that registrar’s and ENS’s terms. A Verified payee badge means only that, when checked, the named ENS records listed this service’s address and payout wallet. It is not an endorsement, an audit or a statement about the seller’s identity, quality or legality.
8. Prohibited use
You may not use the Service to:
- sell or buy anything illegal, or facilitate fraud, money laundering, terrorist financing, sanctions evasion or other financial crime;
- infringe intellectual property or privacy rights, or distribute malware or harmful content;
- impersonate any person or organization, or misrepresent who receives payment;
- attack, overload, scan or interfere with the Service, other users or any upstream service, including using the gateway to reach networks you are not authorized to access;
- drain or abuse the gas we pay for settlement, or otherwise game the Service’s economics;
- scrape, copy or resell the Service except through its public interfaces.
9. Third-party services
The Service relies on third parties we do not control, including Robinhood Chain, the USDG stablecoin issued by Paxos, Ethereum and ENS, wallet providers and WalletConnect/Reown, RPC providers and Cloudflare. Their availability, behavior and terms are their own. We are not responsible for them.
10. Intellectual property
The Service, its software, design and content belong to us or our licensors, except for content you submit. You keep ownership of your listing content and grant us a worldwide, non-exclusive, royalty-free license to host, display, index and distribute it (including in the public discovery feed) to operate and promote the Service.
11. Disclaimers
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT. We do not warrant that the Service will be uninterrupted, error-free or secure, or that any listing is accurate, lawful or available. Blockchain transactions are irreversible and smart contracts may contain bugs. See the Disclaimer.
12. Limitation of liability
TO THE FULLEST EXTENT PERMITTED BY LAW, ONLY BUY BITCOIN LLC AND ITS MEMBERS, OFFICERS, EMPLOYEES AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, DIGITAL ASSETS OR GOODWILL, ARISING FROM OR RELATED TO THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING FROM OR RELATED TO THE SERVICE WILL NOT EXCEED ONE HUNDRED U.S. DOLLARS (US$100). Some jurisdictions do not allow certain limitations, so some of these may not apply to you.
13. Indemnity
You will defend, indemnify and hold harmless Only Buy Bitcoin LLC from any claims, losses and expenses (including reasonable legal fees) arising from your listings, your services, your use of the Service or your breach of these Terms or any law.
14. Suspension and termination
You may stop using the Service at any time and may pause or delist your services from the dashboard. We may suspend or end your access, or remove listings, at any time. Records of payments already settled on-chain cannot be removed from the blockchain. Sections that by their nature should survive termination will survive.
15. Governing law and disputes
These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws rules. Any dispute arising from or relating to these Terms or the Service will be brought exclusively in the state or federal courts located in Delaware, and you consent to their jurisdiction. Before filing a claim, you agree to contact us at contact@x402fi.dev and try in good faith to resolve it informally for 30 days.
16. Changes
We may update these Terms. We will change the effective date above, and material changes will be posted on the Service. Continued use after changes take effect means you accept them.
