This is the Eulerpool IEX Cloud alternative — the same institutional feed behind the terminal, exposed as JSON. Free plan included. No credit card.
IEX Cloud shut down in 2024. This is the migration map — quotes, financials, dividends, news — with before/after paths.

Call it
Endpoint /v1/equities/{ticker}/quote. Works with Python, JavaScript, Go, R, Excel, and raw HTTP.
curl -H 'Authorization: Bearer YOUR_KEY' \
'https://api.eulerpool.com/v1/equities/{ticker}/quote'Authentication
Send Authorization: Bearer YOUR_KEY. Keys are created at register in under a minute. Official SDKs take the key in the constructor; Excel stores it in the add-in settings. There is no key-in-query-string mode — do not paste tokens into public notebooks.
Primary route for this article: /v1/equities/{ticker}/quote. Docs: /financial-data-api/iex-cloud-alternative.
Coverage and freshness
Eulerpool maps 100,000+ securities across 90+ exchanges. IEX Cloud alternative 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.
What else is on the same key
Equities, ETFs, options, FX, crypto, commodities, Treasuries, macro, filings, ownership, and alternative data share the same auth and the same object shapes. You do not open a second vendor when the dashboard grows past last price.
Pricing reality
The free tier is 100,000 requests per month — the same data quality as paid plans. Paid plans raise volume and unlock real-time data. See API pricing — published numbers, not “contact sales” for the first useful row.
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 IEX Cloud alternative 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 it is for
- Quant research — pandas/R dataframes, point-in-time fields, 20+ years of history where the source publishes 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 IEX Cloud alternative.
- Spreadsheets — the Excel and Google Sheets add-in covers the same endpoints as REST.
