  • 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 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 a…

  • spv_verify

    Verify 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 / rejected / inconclusive. This is the trustless core: you sen…

  • proofpack

    For 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 headers it syncs over the BSV P2P network BEFORE serving, so…

  • 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. Priced per call (pay over HTTP with an x402 payment — see /pay).

  • 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. Priced per call (pay over HTTP with an x402 payment — see /pay).

  • service_status

    Report whether anchoring is currently working. Call this if a tool reports something stored but not anchored.
