Native HTTP 402 and the x402 protocol. AI agents pay your API, your services, and your merchants directly — no human in the loop.
Respond 402 with a price; the agent pays in USDC and retries. We handle settlement per call.
Spend limits, rate limits, and allowlists per agent identity. Kill switch included.
Agent spending wallets refill from treasury on thresholds, so the loop never stalls.
Request
app.get("/v1/research", x402({
price: "0.42",
token: "USDC",
payee: "mizu.studio"
}), handler);
A 402 response names the price. The agent pays in USDC, retries, and gets the resource — settlement happens per call, with no card on file and no invoice at month-end.
Tell us about your flow — we'll come back with a sub-account, a fee quote, and a single integration path.
