Independently verify a TaScan Action Receipt JWS (protocol 6.8, POST /receipts/verify): size, envelope, signature, issuer origin, key lifecycle, hashing profile, value semantics, schema and chain check, with an online issued/serial check for the reference issuer. Public route: no TaScan scope is required by the API itself, though this MCP connection still needs some valid key to place any tools/call. Works for both the full and the public export profile. Keys come only from the issuer's own well-known key document (https://app.tascan.io/.well-known/tascan-receipt-keys.json for the reference issuer, or the equivalent well-known path for a foreign one) — this tool never supplies keys itself. Never verifies locally — always calls the reference verifier.
