bsv.cx

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.

Look up a sha256 across EVERY bsv.cx protocol — notary timestamps, verifiable-fetch receipts, notarized captures, web-page archives, Merkle batch roots and attestations — and return when it was anchored and the transaction that proves it. A hash anchored by any of these counts as found. Free, and ne

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.

Fetch the manifest for a previous archive_url capture: when it was taken, and its proof. Free.

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. 10 free calls, then priced per call.

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. 10 free calls, then priced per call.

Report whether anchoring is currently working, plus free-trial POOL status. The trial is a shared pool with a per-caller cap — not a personal balance — so 'open' means the pool has calls left, NOT that you personally do. Call this if a tool reports something stored but not anchored.
