How this service works
[BATCH+PROOF] Full x402 service demand roster, latest day: demand_class, calls_30d, unique_payers_30d, score_total, liveness_state, lifecycle, record_hash per service. Model demand-v1, refreshed daily from the public CDP catalogue; unique_payers_30d is a lower bound, never a sum. DEGRADED DELIVERY, see unavailable_fields - the five-axis sub-scores, action_hint, tier and verified are empty. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.09 per call.
Output
A JSON array of records — one per x402 service — each containing: demand_class (categorical demand tier), calls_30d (total calls in the last 30 days), unique_payers_30d (lower-bound count of distinct payers), score_total (aggregate demand score), liveness_state (current operational status), lifecycle (stage such as active/deprecated), and record_hash (integrity hash). Optionally includes _hash_core per row for offline verification. Note: five-axis sub-scores, action_hint, tier, and verified fields are currently empty (DEGRADED DELIVERY). Returns 422 no_charge if no data is available.
Example use cases
Ranking active x402 APIs by demand
“Give me today's full x402 service demand roster and sort it by score_total so I can see which APIs are most popular right now.”
Monitoring liveness and lifecycle of x402 services
“Pull the current x402 demand roster and flag any services that are not in an active liveness state or are in a deprecated lifecycle stage.”
Offline integrity verification of demand data
“Fetch the full x402 demand scorecard with the verifiable hash preimages included, so I can recompute the record hashes myself and confirm the data hasn't been tampered with.”
Technical details
Endpoint
GEThttps://api.truthbear.co/trust/scorecard?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, daily-refreshed demand overview across all x402 services in one call — especially when you want to rank, filter, or verify services by demand score, liveness, or lifecycle stage. Prefer this over per-service endpoints when you need the full roster rather than a single service's details. Useful for marketplace monitoring, due diligence on x402 API adoption, or building dashboards over the CDP catalogue.
Side effects
- 422 no_charge returned when no data exists for the requested period — not billed
- Five-axis sub-scores, action_hint, tier, and verified fields are empty due to degraded delivery
- unique_payers_30d is a lower bound and may undercount actual unique payers
- Response may reflect a 24-hour-old snapshot since data refreshes daily
