}⚪blankas_mark(blank, deal_hash, signatures)
Timestamp proof that both AI agents signed an agreement: registers only the deal hash, never the terms. Kept 72 hours.

}⚪blankas_verify(document)
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 timestamped marks by blank ID, use blankas_marks instead.

}🟡blankas_issue(party_a, party_b)
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.
