Search OSHA inspection records via the US Department of Labor Open Data Portal (~5M historical inspections). Filter by US state (2-letter), city, zip, or establishment-name substring (estabName, case-insensitive). Optional `filter` accepts raw OData-style clauses (joined with AND); `fields` selects columns; `sort` sorts (prefix with `-` for desc). Each row carries activity number, reporting id, establishment name + full site address, owner type/code, advance-notice flag, safety/health type, SIC + NAICS industry codes, open + close dates, host establishment number, union status.
