Tools it offers

9 tools, as the server itself reported during our check on Oct 31, 2026.

• notarize_hashAnchor 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
• verify_hashLook 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 transacti
• spv_verifyVerify ANY Bitcoin (BSV) Merkle inclusion proof — a BEEF envelope (BRC-62), a BUMP (BRC-74), or a raw TSC proof — against block headers bsv.cx syncs itself over the BSV P2P network, NOT an explorer. Returns confirmed / r
• proofpackFor any CONFIRMED BSV transaction id, get a freshly SPV-verified bundle: BEEF (BRC-62) and BUMP (BRC-74) plus bsv.cx's own self-synced header-tip attestation. bsv.cx fetches the Merkle proof and folds it against block he
• archive_urlCapture 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_archiveFetch the manifest for a previous archive_url capture: when it was taken, and its proof. Free.
• verifiable_fetchFetch 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. Priced per call (pay over HTTP with an x402 payment — see /pay).
• batch_timestampAnchor 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. Priced per call (pay over HTTP with an x402 payment — see /pay).
• service_statusReport whether anchoring is currently working. Call this if a tool reports something stored but not anchored.
