Truth Bear
[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 orders, not rates. 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. $0.01 per call.
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.
Asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 30 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service Truth Bear and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=Truth%20Bear' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://api.truthbear.co/trust/precheck, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
