Tools (15)

  • btc_price

    Get the current Bitcoin price in USD and other major currencies. Source: mempool.space. Real-time.

  • btc_send_decision

    Returns a composited send-or-wait recommendation for a Bitcoin transaction. Fetches live mempool and fee data, then outputs a machine-actionable verdict (SEND_NOW, WAIT, or URGENT_ONLY) with fee rates in sat/vB, mempool pressure level, and estimated savings if you wait. Ideal for agents that need a single decision call instead of parsing multiple raw mempool endpoints.

  • lightning_address_resolve

    Resolve a Lightning Address (user@domain.com) to a payable BOLT11 invoice for a given amount. Handles the full LNURL-pay protocol internally. Returns the invoice plus min/max sendable amounts for validation.

  • tx_decode_explain

    Fetch a Bitcoin transaction by txid and return a structured, agent-ready summary: type (P2WPKH/P2TR/P2SH/etc.), input/output counts, fees, fee rate in sat/vB, confirmation status, RBF flag, SegWit/Taproot flags, and a one-line agent_summary string ready for LLM context injection. Saves 500-2000 tokens vs parsing raw TX JSON.

  • optimal_send_window

    Bitcoin transaction timing intelligence. Returns a congestion forecast for the next 1-4h, a recommended UTC send window when fees are projected at/below your target, a fee trajectory (rising/stable/falling) with a calibrated confidence score, next-block minimum fee, confirmation targets for 3/6/144 blocks, and an RBF-viability flag. A synthesis layer above raw fee data — the decision an autonomous payment agent needs before broadcasting. Source: mempool.space.

  • json_validate

    Validate JSON, identify its root type, and return normalized JSON plus a SHA-256 content hash.

  • json_extract

    Extract one value from JSON using a simple dot path with array indexes, for example users[0].email.

  • csv_to_json

    Convert CSV, TSV, semicolon, or pipe-delimited text into structured JSON with bounded row output.

  • text_analyze

    Return deterministic text statistics, estimated tokens, reading time, and a SHA-256 content hash.

  • hash_generate

    Generate a SHA-256 or SHA-512 digest in hexadecimal or Base64 form.

  • base64_convert

    Encode UTF-8 text to Base64 or decode Base64 safely, with standard and URL-safe alphabets.

  • timestamp_convert

    Convert Unix seconds, Unix milliseconds, RFC3339, or ISO dates into normalized UTC timestamp forms.

  • uuid_generate

    Generate one to one hundred cryptographically random RFC 4122 UUID version 4 identifiers.

  • url_parse

    Parse an HTTP or HTTPS URL into normalized scheme, host, port, path, query, and fragment fields without fetching it.

  • jwt_decode

    Decode JWT header and payload claims locally without verifying the signature. The response always marks verification as false.
