Pay in the request flow.

Get the quote

Call the route. An unpaid request returns HTTP 402 with the exact USDC amount and supported networks.

Pay and retry

An x402-capable client authorizes payment from its wallet and retries the request. The API returns the result.

A normal browser or plain HTTP client shows the 402 quote but cannot pay automatically. Use an x402-capable client with USDC on Base or Solana.

Built for agents to inspect.

Every discovery surface is public and free to read. There is no signup step or API key to request.

MCP tools are available to payment-aware MCP clients. HTTP routes work with any x402-capable HTTP client.
