`pulse_signed_batch`

Pack: pulse-verity · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

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

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”] }).

Parameters

Name	Type	Required	Description
`symbols`	array	yes	Up to 100 tickers. A comma-separated string is also accepted.
`items`	string	no

Always returns: requested, returned, observations, each_row_signed, source

Field	Type	Description

`not_served`	array \| null	Symbols requested but absent from Pulse’s response
`each_row_signed`	string	Reminder each observation is independently verifiable
`source`	string	Constant: Pulse Verity Index (thepulse.markets)
`not_served_note`	string	Explains why not_served exists and how to read it, when at least one requested symbol got no print.
