コンテキストコスト
これは、サーバーのツールがモデルのコンテキストに読み込まれるたびに消費されるおおよそのトークン数です。数が多いほど、ほかのタスクに使える注意が減ります。

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

}🟡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.

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).
