}Neutral, third-party access to official public records — US federal agencies, named registries and standards bodies — where every paid record ships an offline-recomputable record_hash and an Ed25519-signed citation. Pay per call in USDC via x402. No account, no API key.
Truth Bear restates official records faithfully; it does not adjudicate, advise, or endorse. The authoritative source is the official publisher named in every citation — verify and dispute there.
JSON-RPC 2.0 over HTTP POST (initialize / tools/list / tools/call). No key needed to list or verify; paid tools return a real x402 payment challenge you settle from your own wallet.
Not the raw public number (free at its source) — the aggregation + official-source provenance + offline cryptographic verifiability, pre-joined into one schema.
Every paid record carries a record_hash (canonical sha256, independently recomputable) and an Ed25519 citation. SEC-filing settlement evidence also ships a durable_anchor (an immutable SEC accession + permanent document URL) that re-verifies at any time, not only at read time.
Macro (FRED / US Treasury / BLS), energy (EIA), weather & disaster (NOAA / USGS / NWS / SPC / FEMA), health (openFDA / CDC), sanctions (OFAC / EU), trade (USITC), SEC EDGAR filings, and more.
Third-party relay of official records plus cross-source analysis. We warrant faithful relay (the hash recomputes against the cited official source), not the correctness of the source itself. Reference only — not advice, not adjudication, not a market resolution; the independent judgement and decision are the user's own. Full provider notice: https://api.truthbear.co/terms
MIT (this listing/readme). The API itself is a hosted service governed by the Terms above.

Verify a Truth Bear record (free)
FREE. Given a record_hash from any Truth Bear record, look it up and recompute the canonical hash server-side, returning whether it is a genuine Truth Bear official record plus a plain-language reverse lookup of what exactly that hash attests. Use this to check a citation you were handed by another agent or document BEFORE relying on it. No payment, no API key.
record_hash必填Find which signals/entities are covered (free)
FREE coverage + freshness manifest: which signal_id lines exist, how many entities each covers, and fresh/recent/stale counts - so you can check "is my entity covered and how fresh" BEFORE paying. Optional filters: industry, signal_id, entity.
fullentityindustrysignal_idGet the x402 payment challenge for a paid record
Returns the REAL x402 payment challenge (accepts[]: network / asset / payTo / amount) for the paid endpoint that serves a given signal_id+entity, or any listed endpoint addressed directly by `path`. This tool does NOT deliver paid data and does NOT take payment - MCP has no payment layer. Pay at the returned url with your own x402 client (USDC on Base or Solana, gasless EIP-3009; pay from a plain EOA) and you receive the record directly, with record_hash you can verify offline. This tool only fetches the 402 challenge; it delivers no paid data and collects no payment.
dimpathentitysignal_idHow can I actually buy this? (free)
FREE. Ask how to pay for a listed endpoint and get every channel with its REAL status - including the ones that are wired but not open yet. Three channels exist: x402 micropayment (for an agent with a funded USDC wallet on Base), a stateless subscription Bearer token (for a person or team - no wallet, no private key, no account), and a card rail. This tool takes no payment and holds no key; it only tells you which doors exist and which are open today.
pathCross-check a line of official series & recompute the verdict (free)
FREE. Cross-verify one GAUGE interweave line: it returns each official series ("leg") in the line with its own record_hash, current/previous values, expected direction and per-leg minMove deadband, plus a count-style state (directions_matched / direction_mismatch / inverse_consistent / not_comparable / insufficient) and N-of-M. Everything needed to recompute the verdict OFFLINE is in the response - verify each leg hash with verify_citation, then recompute dir=sign(current-previous) with the minMove deadband. Descriptive only: no forecast, no causation, no advice. No payment, no API key.
