No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/pulse_verify_print for the schema, then POST the same URL with its arguments for the data.

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” }).
