Is bsv.cx live?

Yes — it answered the hub's last check (checked 26m ago). It answered 100% of checks over the last 30 days.

Is bsv.cx free to use?

Yes — the hub reached it with no key and no payment.

What tools does bsv.cx have?

9 tools: notarize_hash, verify_hash, spv_verify, batch_timestamp, archive_url, verifiable_fetch, get_archive, service_status, ….

Is bsv.cx safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• proofpack reads 0.006 BSV paid never probed

  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).

• notarize_hash changes data unknown never probed

  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 reads unknown never probed

  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.

• spv_verify reads unknown never probed

  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.

• batch_timestamp changes data unknown never probed

  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).

• archive_url changes data unknown never probed

  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.
