OperationId:equities_sp500_constituents

Returns the full S&P 500 constituent list (503 entries) with GICS sector + sub-industry classifications + date-added + SEC EDGAR CIK identifiers. Sourced from public Wikipedia (CC-BY-SA-4.0) membership announcements via daily auto-refresh blob; hardcoded 503-entry snapshot serves as defence-in-depth fallback when the blob is unavailable. Filter by ?sector=<GICS sector> or ?sub_industry=<GICS sub-industry> to narrow the list. Use case: UC-2 Earnings Whiplash Map filters earnings calendar by SPX members; UC-1 Institutional Footprint cross-references CIK to /sec/13f endpoints. The data_source field exposes whether the response was served from the Wikipedia blob (blob_wikipedia) or the hardcoded fallback (hardcoded_fallback).
