For developers
Sell your API to agents.Settled in USDC, on-chain.
Register a monetised route, grab a test or live key, and add one middleware. Any endpoint returns a signed x402 challenge; agents pay in USDC and you settle on-chain — with signed webhooks and balances.
01
Register a route
Define the route + price in the dashboard; issue a test or live API key.
02
Add the SDK
One middleware — Express, Next.js, FastAPI, Django, Laravel, Go, Spring Boot, ASP.NET Core, or Rails. One frozen X402v1 contract.
03
Agents pay per call
Your route returns a signed 402; agents settle USDC over x402 on Base.
04
Settle & reconcile
On-chain 95/5 split, batched payouts, and signed retried webhooks.
- Nine official SDKs, byte-identical signing (one frozen contract)
- Test mode with sandbox keys — full loop before going live
- Signed webhooks: payment.settled, payout.sent, payout.failed
- On-chain settlement + immutable payout snapshots
