https://keystone-opportunity-api.keystone-opportunity.workers.dev/v1/x402/conformanceShares a payout wallet with 1 other endpoint — its adoption is attributed from that shared wallet's traffic, not earned exclusively.
Probe an x402 URL without paying it: validate the live HTTP 402 challenge, v2 payment schema, Base USDC amount, payTo/network fields, and OpenAPI-to-live price consistency.

How often it was reachable when we probed it (weight 35%).
How quickly it answers when it is up — fast scores high (weight 20%).
Whether it serves over working TLS / https (weight 15%).
Whether the operator disclosed what it does — description, schema, identity (weight 15%).
Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).
Confidence 52% — how much probe evidence backs this score. A thin history is flagged, not hidden.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.

This payout wallet is shared: figures cover all 2 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
Linked by wallet — likely same operator
