🟢get_notary_info
No auth needed. Price, min confirmations, spec version, and supported hash algorithms.
输入模式

"properties": {},
"title": "get_notary_infoArguments"
}🟡prepare_anchor(content_hash, from_address, api_key, algorithm, idempotency_key)
Anchors content_hash on chain. Returns a partially-signed transaction (operator co-signed its fee input) -- add your own witness for from_address and submit. idempotency_key (optional) returns the same prior result on retry instead of building a new transaction.

}🟡prepare_decision_log(content_hash, seq, from_address, api_key, algorithm, ...)
Appends one entry to your hash-chained decision log. content_hash is the hash of your own RFC-8785-canonicalized decision record (never send the record itself -- see docs/decision-record-v1.md). seq starts at 0 and increments by 1 each call; prev must equal the previous entry's content_hash (omit only for seq=0). Returns a partially-signed transaction to sign and submit yourself.

}🟢check_anchor_status(proof_id, api_key)
Looks up a previously prepared anchor or decision-log entry by proof_id. Requires the api_key that created it.

}🟢verify_proof(tx_hash, content_hash, content)
Authoritative on-chain check by tx_hash (and/or content_hash to compare against). No auth needed -- anyone holding a tx hash can verify it, like a receipt. Optionally pass content to re-hash locally server-side (never stored/logged).

}⚪verify_decision_chain(agent_ref)
Independently checks a decision-log chain's integrity from chain data alone (gap-free seq, prev matches, each entry anchored). No auth needed.
