Server tool list (4)

Raw names from tools/list. Only developers need these.

verify_citationFREE. 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.
find_signalFREE 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.
get_official_recordReturns 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.
purchase_optionsFREE. 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.
