Graded x402 Gateway

Other

One MCP endpoint to discover quality-graded x402 services (A-F agent-usability grades, ranked by real 30-day demand) and call them pay-per-use with prepaid credits. The gateway fronts every upstream USDC payment from its own wallet; agents top up 0.10 USDC packs via x402 (fiat coming). Free discovery + REST mirror.

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

REQUEST / RESPONSE EXAMPLE

An unpaid request to GET /mcp returns HTTP 402 with the payment terms. Settle onchain via your facilitator, then retry with the X-Payment header.

// request
curl -i 'https://gateway.leeworks.dev/mcp'

No 402 response body has been captured for this service yet.

OVER TIME

All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/graded-x402-gateway/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
