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

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. ${PRINT_NOTE} 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” }).

Parameters

Name	Type	Required	Description
`symbol`	string	yes	Asset ticker as Pulse spells it, e.g. BTC, ETH, SOL. pulse_asset_catalog lists coverage.
