How payment works
- MCP client calls a tool (e.g.
get_market_overview). - MCP server requests
https://...kerdos.../api/market-overview. - Kerdos server returns
402 Payment Requiredwith a payment challenge. @x402/fetchsigns a USDCtransferWithAuthorizationusing your key.- Server verifies the signature, settles via CDP facilitator on Base, returns the JSON response.
End-to-end latency: ~1-2 seconds per call. No interactive approval — payment happens transparently.
Provider
