form5500_filing

Pack: form5500 · Endpoint: https://gateway.pipeworx.io/form5500/mcp

Get Form 5500 filing detail from the DOL EFAST2 index. Pass ack_id for a single filing (sponsor, plan name/number, participant counts, begin/end-of-year plan assets, plan type, filing date, and full filing PDF URL). Pass ein instead to get a plan sponsor’s full filing history (all Form 5500 filings for that EIN, newest first). Note: line-item detail such as Schedule C service providers is not in the search index — the returned pdf_url links to the complete filing.
