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. |
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). |
get_archive | Fetch the manifest for a previous archive_url capture: when it was taken, and its proof. Free. |
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. |
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 you receive a bundle that already confirms — verifiable by any @bsv/sdk client with no bsv.cx-specific code. Verification itself is free at /spv/verify; this does the fetch + fold + package for you and is 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. |
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 send only the proof (never the root), we fold the root ourselves and check it against a header we hold — so you never have to trust bsv.cx. Works for ANY txid's proof, not just bsv.cx's own anchors. 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). |
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 as found. Free, and never rate-limited into unavailability. |
