LIVE ENDPOINT METADATA
[SIGNAL+PROOF] Demand record for one x402 service (?service=): demand_class (REAL/SOLO/PROBE/WASH), calls_30d, unique_payers_30d, score_total, liveness_state, lifecycle, record_hash. Model demand-v1, refreshed daily from the public CDP catalogue; score_total is an ordering key, not a rating. DEGRADED DELIVERY, see unavailable_fields - tier, verified, action_hint and the five-axis sub-scores are empty. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

Source catalog records are retained separately from live endpoint observations. Sonar score, uptime, and latency are advisory metrics. CDP indexing is not inferred from validation.
