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

Who sells wholesale power TO a given counterparty — the reverse of eqr_contracts_search. Aggregates FERC EQR contracts by seller for a counterparty name match, returning each seller’s contract count, the quarter range they appear in, and the distinct products sold. Answers “who sells power to PacifiCorp” / “which generators have contracts with ” directly, which a single-table filter cannot (it needs a group-by across all matching contracts). Sourced from FERC EQR via PUDL (CC-BY-4.0), Phase 1 (contract terms only).

Parameters

Name	Type	Required	Description
`counterparty`	string	yes	Counterparty/customer company name, substring match, e.g. “PacifiCorp”.
`quarter_from`	string	no	Earliest quarter to include, format “2020q1”.
`quarter_to`	string	no	Latest quarter to include, format “2026q2”.
`limit`	number	no	Max sellers to return (default 25, max 100).
