What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

• btc_price

  Get the current Bitcoin price in USD and other major currencies. Source: mempool.space. Real-time. Each reading carries source (the URL read), fetched_at (UTC, RFC 3339) and source_sha256 (SHA-256 of the upstream body as served).

• 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

• 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.

• 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

• 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.

• business_ratios

  Compute cash runway in months, cash buffer days, current ratio, quick ratio, debt to equity, DSO, DIO, DPO and cash conversion cycle from any subset of a business's own cash, monthly flow and balance sheet figures. Arithmetic only, no network. Each value carries its formula and t
