Coverage and freshness

Eulerpool maps 100,000+ securities across 90+ exchanges. ai-powered earnings call analysis API rides that same reference layer — identifiers resolve through ticker, name, ISIN, or CUSIP via search, so a European name is not a dead end. History depth depends on the source: prices and macro go back 100+ years, 1-minute bars to 2010, 13F to 2013.

Paid plans can stream quotes over WebSocket; the free plan uses REST with a 15-minute delay on real-time equity fields. Fundamentals, ownership, and calendars are identical on every plan. Rate-limit headers ship on every response. Batch routes (up to 100 symbols) count as one request.

Why it exists

Most teams land here after fighting Yahoo Finance scrapers, Alpha Vantage’s 25-request/day ceiling, or a Polygon bill that ignored fundamentals. Eulerpool is a licensed ai-powered earnings call analysis API with statements, estimates, filings, and macro on the same key — and a terms of service you can actually show legal.

Deep comparisons live here: vs Alpha Vantage, vs Polygon, Yahoo Finance alternative, best stock market APIs in 2026.

Who uses it

  • Fintech apps — watchlists, screeners, and portfolio views without relicensing Bloomberg for every customer.
  • AI agents — typed JSON and a native MCP server so models stop inventing numbers for ai-powered earnings call analysis API.
  • Spreadsheets — the Excel and Google Sheets add-in covers the same endpoints as REST.
