Definition
What are AI agent payments?
AI agent payments are payments made by an AI agent without human intervention. The AI Agent calls an API or service. The service responds that payment is required and how to pay in a stablecoin like USDC. The agent pays on a public blockchain in under a second, and the API returns the response. No checkout, no card, no human approving the charge.
TRXN is the gateway that lets you accept those payments. Take your existing API, even one that isn't x402-compliant, and make it AI agent payable: pick the endpoint you want to charge for, set a price per request, and connect the wallet where funds should land. From there, every agent call comes through TRXN. We tell the agent what to pay, verify the payment on-chain, and roll each request into a daily invoice with the paying agent tracked as a customer. The money goes straight to your wallet. We never hold it.
Three steps
How it works
Pick your endpoint
Choose the API route you want to charge for. Point TRXN at your existing API and tell us which endpoints are paid.
Set the price
Price each request in plain dollars. TRXN converts to crypto at the moment of payment, so you always know the exact amount you earned.
The agent pays
An agent calls your endpoint and pays automatically in USDC. No account, no card, no human in the loop. The payment lands in your wallet, not ours.
You get a clean record
TRXN verifies the payment on-chain and rolls it into a daily invoice, with every agent tracked as a customer. Your books stay tax-ready.
Why TRXN
The gateway that turns payments into records
Zero custody
We verify and record the payment. The crypto goes straight from the payer to your wallet. TRXN never touches your funds.
Payments become real records
Raw agent payments are anonymous. TRXN turns them into daily invoices, matched to customers, with tax-ready reports your accountant can actually use.
Built for the agent economy
Agents already speak x402, the open standard for paying over the web. TRXN runs a hosted gateway, so you can sell to them today and account for every dollar.
Run on x402, hosted for you
x402 is the open protocol that lets software pay over the web. It uses the HTTP 402 "Payment Required" response to settle in stablecoins, with no API keys and no manual billing. Agents already support it.
Standing up your own x402 gateway means running the infrastructure, reconciling payments, and working out who paid for what. TRXN runs that gateway for you. Point your endpoint at TRXN, set your price, and you get per-request payments, daily invoices, and full customer tracking from day one. You write your API. We handle the x402 payment infrastructure for you, so you don't have to.

Supported assets across multiple chains
-
Yes. An agent calls your endpoint and pays in USDC as part of the request. There is no signup, no card, and no manual approval. The payment settles on-chain in under a second.
-
x402 is the standard agents use to pay over the web. TRXN runs a hosted x402 gateway in front of your API, so you get the payments without building or maintaining the infrastructure yourself.
-
No. TRXN verifies and records each payment, and the crypto goes straight from the payer to your wallet. We never take custody.
-
Your TRXN account gets a subdomain on our gateway. As agents pay through it, each wallet maps to an existing customer in your account, or gets added as a new customer on first payment. Every payment is attributed to a real customer, so your invoices, tax records, and audit trail stay compliant.
-
There are no platform fees and no monthly minimums. You pay based on verified transaction volume, plus nominal on-chain gas. Early access members lock in founding pricing.
