payment-ready until 2026-08-27
Official-source signals + unified rulers, each record ships record_hash (canonical sha256, recomputable offline; free /gauge/verify to cross-check) - pay-per-call via x402 (USDC on Base, no API key). Sources are official government records and named registries: US federal agencies (USGS, NOAA, NWS, EPA, SEC EDGAR, openFDA, EIA, BLS, FAA, US CBP, USTR, USITC, Federal Register) plus IMF PortWatch, UNFCCC and standards-body feeds. Cryptographic provenance on every paid response: an Ed25519-signed citation (issuer did:key published in the service manifest) makes delivery tamper-evident and auditable offline, with no call back to us. Pure description, no judgement, no prediction; the rest, you decide. GAUGE engine: six forensic lines (stablecoin / AI-tool / AI-dependency / promise / carbon / climate-policy) + environmental / hydrology / air-quality / precipitation / grid / regulatory-filing signals. Free preview + free /verify before you pay.
Pay from $0.005 to $0.35 per request in USDC on Base / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share is a concentration signal, not part of the ranking score.

] OVER TIME
All charts use the 90d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/truth-bear/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
