notarize_hash
Anchor a sha256 digest in a Bitcoin SV transaction, proving the content existed at this time. Send ONLY the hash — the content never leaves your machine, and bsv.cx cannot see what was hashed. Free. Idempotent: the same hash returns the same record.
verify_hash
Look up a previously notarized sha256 and return when it was timestamped and the transaction that proves it. Free, and never rate-limited into unavailability — verifying a proof must always work.
archive_url
Capture a web page as it looks right now — screenshot and text — and anchor a hash of that capture on-chain. Use this before relying on a page you cite, so a later edit or deletion cannot be denied. Free.
get_archive
Fetch the manifest for a previous archive_url capture: when it was taken, and its proof. Free.
verifiable_fetch
Fetch a URL as readable text AND get a receipt anchoring a hash of the exact bytes returned, so you can later prove what the page said when you read it. 3 free calls, then priced per call.
batch_timestamp
Anchor a Merkle root over many sha256 digests in a single transaction — far cheaper per item than notarizing each one. Each hash gets an inclusion proof. 3 free calls, then priced per call.
service_status
Report whether anchoring is currently working and how much of the free trial remains. Call this if a tool reports something stored but not anchored.

}Timestamp and verify evidence on-chain. Let your agent prove what it saw and when.
bsv.cx gives an AI agent verifiable memory. Timestamp a hash of any output, archive a web page as it looked, or fetch a URL with a receipt proving what came back — each anchored in a Bitcoin SV transaction. Verification is free and needs no trust in bsv.cx: anyone can check the proof on any explorer.
