Every relay is measured twice over. Over WebSocket a genuine REQ query is sent and the connection time, the time to end of stored events and the number of events returned are recorded — a relay that accepts the connection and then stays silent is the failure mode a reachability ping cannot see.

Fetches kind 3 contact lists over up to twelve relays. Because kind 3 is replaceable, several relays regularly hold different versions; only the one with the highest created_at is used and the answer states which relays carried that version and how many older versions were seen, so a stale relay never quietly overwrites a current list. At depth 1 the answer is the account and its outgoing follows.

Fetches https://domain/.well-known/nostr.json with the name query parameter and reads the mapping the domain publishes. The answer states the resolved public key in hex and as npub, the relay hints the document lists for that key, and the HTTP status and final URL after redirects, so a redirect to a login page is distinguishable from a genuine answer. Given an expected public key, the comparison is made and the result is reported as an explicit match or mismatch rather than left to the caller.

Provider reliability — the supply-side reputation the 6-question agent loop needs. Observed at our door: which origins agents chose via the free router and whether it actually helped — helped-rate (Laplace-smoothed), repeat-rate, and sample confidence. Not asserted, measured; a provider is neutral until agents report back. HOW TO CALL: GET /api/demand/reliability?days=90&limit=25 PARAMETERS: days — lookback window, 1-365 (default 90) limit — providers returned, 1-100 (default 25) RESPONSE: providers[] {origin, reliability, confidence, helped, outcomes_rated, referrals, repeat_rate}. Aggregate-only; thin rows withheld. PRICING: $0.05 per call.
