Tools: stamp_hash verify_receipt
stamp_hash | Returns a signed receipt {sha256, stamped_at, key_id, signature, public_key_url}: a booklint-family service saw this hash at stamped_at, signed with key key_id. Send ONLY a SHA-256 hex digest (64 characters). We never see or store the document — only the hash you send. This is not legal proof, notary service, evidence, or a certificate of anything. Not advice. params: sha256*, api_key |
verify_receipt | Checks a receipt from stamp_hash against the published public keys (same check as POST /v1/verify; pass the receipt fields as arguments). Returns valid true or false with a reason. valid true means only that this service signed that hash and time with that key. This is not legal proof, notary service, evidence, or a certificate of anything. params: sha256*, stamped_at*, key_id*, signature*, public_key_url, statement, api_key |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
