Is there a Financial API (for use in software development with a programming language such as Java, Python, or .NET) that provides Options Chains?

I understand Yahoo had such an API and it was terminated in 2017. Does a replacement exist, even if it is not free?


You can try tradier.com. I haven't used them in a while so I'm not sure how their services have changed but their api used to support getting option chains for various expiration dates.


TD Ameritrade's API provides option chains in real time. See https://developer.tdameritrade.com/option-chains/apis/get/marketdata/chains for more info, and see https://pastebin.com/nxGFc3ef for an example of an option chain that I recently downloaded using the API.
