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 Required with a payment challenge.
@x402/fetch signs a USDC transferWithAuthorization using 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.
