x402 Trinity is a marketplace where sellers list APIs, files and digital products, and buyers pay for them per use in USDC on the Base network. Using the site means accepting these terms.
One account covers buying and selling. Keep your password and your API keys to yourself — anything done through your account is treated as done by you.
A platform fee applies to every sale. The exact amount, and who pays it, is set out on the Payouts & fees page, which forms part of these terms.
Payments settle on a public blockchain and cannot be reversed. We never hold your funds: a sale splits between the seller and the platform fee in the same transaction the buyer pays in.
If a purchase fails to deliver, the buyer is not charged for it.
You are responsible for what you sell. You must have the right to sell it, it has to work as described, and it has to be legal.
What you buy is the seller’s, not ours — we are the marketplace and the payment rail. A purchase is for your own use unless the seller says otherwise.
Prepaid request credit does not expire and stays against your account, but it is not refundable in cash.
What it is. You pick a stake, join a queue, and are matched against other players in a supported game. Every player’s stake goes into a pool held by a contract on the Base network. The winning side splits the pool. At every match size that works out to double your stake.
What we take. A surcharge on top of your stake: one cent up to $1, two cents at $2.50, ten cents at $5, twenty-five cents at $10, and 1% on anything above $10. It is added to what you pay and shown before you sign. Nothing is ever taken out of the pool.
Who can enter. You must be 18 or over, and entering is your decision and your responsibility. Staking money on the outcome of a game is restricted or prohibited in some places. It is on you to know whether it is lawful where you are, and we may refuse or remove any entry.
Entry is final. Nothing leaves your wallet while you are waiting in a queue. Once every player in a formed match has accepted and the stakes are taken, the payment has settled on a public blockchain and cannot be reversed — not by us, and not by you.
You can lose. If your side loses, your stake goes to the other side. That is the whole arrangement. Do not stake money you need.
Results. The game publishes no winner we can read, so a result is what the players report. One player on each side — the host named on the match page — names the side that won, within the window shown on the match.
Screenshots. You do not need one when both sides name the same winner; that agreement is what settles the match. A screenshot or recording matters when you are the only side that reports: a submission with nothing attached is never awarded the match on the timer, however long the other side stays silent.
When a result pays itself. If both hosts name the same winner, that side is paid automatically and nobody reviews it. In a one-against-one match, if one side submits with proof and the other has not answered three minutes later, the side that submitted is paid. In a team match that does not apply: both sides must submit, and one submission on its own is never settled on the timer.
When admin settles it. If the two sides name different winners, if a team match is left with one submission, or if anyone reports that a player left before the end screen, the match is held and settled by admin. If neither side submits at all, the match is voided and stakes are returned. The operator’s decision is final, and it is made from what was submitted.
Fair play. Cheating, match-fixing, playing both sides, entering under someone else’s Steam account, or submitting faked or altered proof will void the match and may cost you your stake and your account. One Steam account may be in one match at a time.
Voids. A voided match returns every stake to the wallet it came from. The surcharge is not returned — it has already been spent getting the match on chain.
Your wallet. You pay from the wallet you connect and you are paid to that same wallet. Make sure it is one you control — a prize sent to a wallet you have lost is gone.
The service is provided as it is, without a guarantee of uptime, and third-party endpoints can go down without warning. We are not liable for a seller’s service, for losses caused by an outage, or for what you do with what you buy.
