On: Ask HN: Which sites/platforms do you wish had an API?

[billconan]

I hope some major stock trading website can have api for

1. historical data

2. real-time data

3. trading api

credit card usage/history data (only for myself) that is across all credit card brand.

I'm pretty sure APIs #1/2/3 do exist, although access costs thousands of dollars, making hobbyist usage impractical.

I think IEX has a free API with historical and real-time stock info: https://iextrading.com/developer/docs/

tiingo.com has 1 & 2 (via IEX) and the prices (iirc) are not prohibitively expensive.
