StockFit
StockFit's API turns SEC XBRL filings into structured, queryable endpoints for company financials, institutional/insider ownership flows, ETF exposure, and filing-event timelines, updated daily and authenticated with a bearer token from its developer dashboard. It ships an explicit tiered plan structure — a persistent free tier (34 endpoints) alongside Starter ($15/month, 46 endpoints), Stock and ETF ($39/month each), and Professional ($69/month, 96 endpoints) tiers that unlock progressively more endpoints. A live Origin-header probe of api.stockfit.io returned no Access-Control-Allow-Origin for an arbitrary origin (only a credentialed, origin-restricted CORS policy visible via `Vary: Origin`), correcting the previously-recorded `cors: yes`.
