Implementation notes
When to use IEX Cloud
IEX Cloud is a solid free choice for US equity data when you need real-time quotes (IEX is a registered exchange, so its prices are official), plus fundamentals, news, and options data. The Starter plan gives 50,000 credits/month — enough for a personal dashboard polling ~20 stocks every few hours.
Common pitfalls
- IEX Cloud uses a credit system, not a simple call count. A single quote call costs 1 credit; a bulk quote for 100 symbols costs 100 credits. Fetching historical OHLCV for one symbol over 1 year costs 252 credits (one per trading day). Always calculate credit costs before implementing a feature.
- Real-time price data from IEX reflects only trades executed on the IEX exchange, not the consolidated tape. IEX has about 2-3% of total US equity volume. For NBBO (national best bid/offer) or last-sale prices, IEX data can deviate from consolidated market data.
- The `pk_demo` token works only for AAPL on the `/stable/stock/{symbol}/quote` endpoint. Other endpoints or symbols return 403. Register for a real key — free tier activates immediately.
- IEX Cloud went through ownership changes and restructuring in 2023-2024. Some documentation pages reference endpoints from earlier versions (v1) that have been renamed or moved under `/stable/`. Always use the `/stable/` path prefix rather than versioned paths.
