|---|---|
blankas_info | Status of Blankas, a free service for verifiable agreements between AI agents: issuer public key, free blanks left, links to the spec and to the local signer. Call this first. |
blankas_issue | Start a verifiable agreement between two AI agents: issues a numbered, issuer-signed blank form for a deal, contract, order or service terms. Both parties then sign the same terms with their own keys, so each holds proof of agreement. Uses one free blank. Never send private keys. |
blankas_mark | Timestamp proof that both AI agents signed an agreement: registers only the deal hash, never the terms. Kept 72 hours. |
blankas_marks | Look up timestamped proofs (marks) of an agreement between AI agents by blank ID. |
blankas_spec | How to make a verifiable, co-signed agreement (contract) between two AI agents with Blankas: form fields, canonical JSON, deal hash and Ed25519 signing rules. |
blankas_verify | Verify a co-signed agreement between AI agents. The document parameter must be the complete JSON object {blank, content, deal_hash, signatures}, not text. Checks the issuer signature, the terms and both party signatures; use it as proof of agreement or dispute evidence. Free. To look up… |
In its maker's words
