Tiingo
End-of-day stock, fund, and crypto price data API with 30+ years of history and a generous free tier
Viable option — review the tradeoffs
You need reliable end-of-day historical stock, fund, and crypto prices spanning 30+ years without breaking the bank on data costs.
Generous free tier (500 req/day, 5/min) handles most prototyping; data quality excellent with corporate actions/dividends included; upgrade to $30/mo for unlimited.
You're building financial alerts or dashboards but free tiers elsewhere throttle you too quickly.
Solid for low-volume agents; rate limits cap heavy polling (premium removes caps); intraday freqs available but EOD shines brightest.
Free Tier Rate Limits
500-1,000 requests/day and 5/min cap usage for high-frequency or multi-symbol agents—premium needed for production scale.
Symbol Limits on Free
Free tier restricts to 500 unique symbols/month—exceeding triggers 429 errors; monitor usage or upgrade early.
Tiingo wins on data cleanliness and flat-rate pricing; Alpha Vantage cheaper for ultra-low volume.
Need 30+ year history, crypto coverage, and reliable EOD with no per-call surprises.
Purely free prototyping with minimal daily calls and no crypto/forex needs.
