Tools 6 found in our last check

  • get_notary_info

    No auth needed. Price, min confirmations, spec version, and supported hash algorithms.

  • prepare_anchor

    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

    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…

  • check_anchor_status

    Looks up a previously prepared anchor or decision-log entry by proof_id. Requires the api_key that created it.

  • verify_proof

    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

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