{"jsonrpc":"2.0","id":1,"method":"tools/list"}pulse_signed_price — The current CRYPTOGRAPHICALLY SIGNED index price for one crypto asset, from the Pulse Verity Index across thousands of assets and dozens of venues — this result carries a signature you can verify: pass it unchanged to pulse_verify_print to check it OFFLINE, with no network call, against Pulse's public key. Each print carries signature, kid, grade, the number of independent venues (sources), dispersion in basis points and a confidence interval. Grades: consensus (3+ venues) and blended (2) are settleable; indicative (1 venue) is NOT. Use it when a price has to be defensible — settlement, an audit trail, a dispute — not merely current. Requires a Pulse API key via _apiKey. Example: pulse_signed_price({ symbol: "BTC" }).pulse_signed_batch — Signed index prices for up to 100 crypto assets in ONE call — each row carries its own signature you can verify individually with pulse_verify_print, offline, with no network call, not just the batch as a whole. Use this instead of looping pulse_signed_price: it is one request against the rate limit and every observation still carries its own signature, grade, venue count and interval. Symbols Pulse does not serve come back named in not_served rather than silently missing. Requires a Pulse API key via _apiKey. Example: pulse_signed_batch({ symbols: ["BTC", "ETH", "SOL"] }).pulse_settlement_print — The signed index print Pulse RECORDED nearest a past moment — the tool for settling a contract, pricing an option at expiry, or reconstructing what an asset was worth at a specific timestamp. Returns the observation with its original signature intact — verify it offline with pulse_verify_print, no network call — plus delta_ms, the distance between the time you asked for and the print actually returned; it is the nearest recorded print, never a price synthesised at your exact instant. Accepts ISO-8601 or epoch milliseconds. Requires a Pulse API key via _apiKey. Example: pulse_settlement_print({ symbol: "BTC", at: "2026-09-16T21:41:46.000Z" }).pulse_verify_print — Check whether a Pulse signed price print is authentic and unaltered — pass a print back exactly as a Pulse tool returned it and this recomputes the ECDSA P-256 / SHA-256 signature over the canonical string, entirely OFFLINE with no network call to Pulse. WHAT A valid:true RESULT PROVES: that Pulse asserted this exact price, for this symbol, at this timestamp, at this grade, and that nobody altered any of those fields in transit — it detects a single changed digit of price or a one-millisecond shift in the timestamp. WHAT IT DOES NOT PROVE: that the price is CORRECT or reflects the true market — this checks Pulse's signature, not the world, so a print can verify perfectly and still be a price Pulse itself got wrong. The verification is computed here, not asked of Pulse, so Pulse cannot vouch for a print it never signed and an offline or compromised source cannot turn an invalid print into a valid one. Needs NO API key. Example: pulse_verify_print({ symbol: "BTC", priceText: "76051.0676303142", price: 76051.0676303142, at: "2026-09-16T23:39:30.524Z", grade: "consensus", signature: "wiD005d9...", kid: "pvi-Sl40p5Gj2t_-JyKUhxyg" }).pulse_asset_catalog — Which crypto assets the Pulse Verity Index covers, at what grade, across how many venues, and how fast each one actually updates — cadence measured per asset from its own update intervals rather than from a poll schedule. Filter by coverage band (real-time, five-second, ten-second, slow, unavailable) or status (consensus, blended, indicative). Call this to find out whether a symbol is covered, and how thin it is, before quoting it. NOTE: these rows are UNSIGNED, including their prices — read a verifiable number through pulse_signed_price. Requires a Pulse API key via _apiKey. Example: pulse_asset_catalog({ limit: 5 }).pulse_key_ring — The public keys Pulse signs its price prints with, as PEM and JWK, plus the signing algorithm and the exact canonical string format — everything needed to verify a signed print yourself, OFFLINE, with no network call to Pulse. Use it to write your own verifier, or to audit what pulse_verify_print (this pack's ready-made offline checker) is checking against. Needs NO API key. Example: pulse_key_ring({}).Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
