Twelvedata Review

Worth it

Should I use Twelvedata?

Now Live: Cboe Europe real-time data for all major European stocks. - twelvedata.com

Buy if you're a developer or algo trader needing stock/forex/crypto data via API — the free tier and $329/mo top individual plan cover hobby to startup scale. Skip it if you want a finished investing app or terminal-grade institutional feeds.

Gotchas - check before you buy

medium

Cheaper plans carry tight API credit limits; heavy real-time use pushes you to the $329/mo Ultra tier

medium

Per-exchange real-time entitlements vary by plan — verify your markets before committing

medium

Guess: deep historical intraday depth is likely gated to higher tiers — check your lookback needs

low

Startup credits require an eligibility application, not automatic

Well-reviewed market-data API with a free tier; great for devs and algo traders, useless if you want a ready-made stock app.
