r/fintech – Stock API with best rate limits


Looking for a stock API which has high rate limits per minute for basic quote/company info requests. For my specific use-case, I would like to be able to look up 1000’s or many 1000’s of symbols per minute. The only datapoint that should ideally be ‘fresh’ for these calls is market cap, so these are fairly simple requests.

I’ve taken a look at a lot of APIS, and iexcloud.io, and alphavantage.io look nice. The highest offering between the two is 1200 calls/minute.

I could ‘break up’ my calls or I could create and maintain an index of 1000’s of stocks to look up locally, but would like to avoid this if there’s a cost-effective solution.

Appreciate any insights.
