Options Data APIs
Options data APIs split between raw market feeds and modeled analytics. Tradier returns US option chains, quotes and history alongside its brokerage API on a freemium plan, and Intrinio sells US stock and options feeds with a free trial. Helium takes a different approach, offering AI-modeled option pricing, forecast ranges and ranked options trades rather than exchange data. Free Stock APIs →

Choosing an Options Data API
Is there a free Options Data API?
Yes. Tradier has a free tier alongside paid plans. See all free Stock APIs.
Which Options Data APIs work without an API key?
All of them need a key or account. Tradier gives one out free when you sign up.
Can I use Options Data APIs in a commercial project?
Helium permits commercial use. Intrinio restricts it, for example to non-commercial or attributed use, so read the terms first.
