"blank_id": {
"type": "string",
"description": "Blank ID, for example BLK-000001-7afb11"

}⚪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.
Eingabe-Schema
{
"type": "object",
"properties": {
"blank": {
"description": "The issued blank object exactly as returned by blankas_issue"

"additionalProperties": true
}⚪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.
Eingabe-Schema
{
"type": "object",
"properties": {
"party_a": {
"description": "Public keys of party A: object with sign (Ed25519) and box (X25519), each 32 raw bytes as base64url without padding"
},
"party_b": {
"description": "Public keys of party B in the same format as party_a, different from party A"
}
},
"required": [
"party_a",
"party_b"
],
"$schema": "https://json-schema.org/draft/2020-12/schema",
"additionalProperties": true
}⚪blankas_spec
