`hsr_search`

Pack: hsr-notices · Endpoint: https://gateway.pipeworx.io/hsr-notices/mcp

Search FTC Hart-Scott-Rodino (HSR) early-termination notices by acquirer or target company name. Matches against the notice title, which embeds both parties and the transaction number, so a partial or one-sided company/fund name finds every notice that mentions it. Use this to check “did this merger get antitrust clearance” or “has the FTC granted HSR early termination for this deal.” Example: hsr_search({ party: “Blockbuster”, limit: 25 })

Parameters

Name	Type	Required	Description
`party`	string	yes	Company or fund name to search for, e.g. “Blockbuster” or “Carl C. Icahn”. Matches anywhere in the notice title (as-filed legal name, so include known fund suffixes like “L.P.” if a plain name misses).
`since`	string	no	Optional — only return notices on or after this date, YYYY-MM-DD.
`limit`	number	no	Max notices to return, newest first. Default 25, max 100.
`_apiKey`	string	no	Optional — your own api.data.gov key for higher limits; omit to use the shared Pipeworx key.
