You should also consider https://Polygon.io to be on this list.
Polygon.io is really slow and their websockets are not stable. We are getting socket error EVERY week. So, NEVER AGAIN.
I have the same problem with Polygon.
When I make an API request to polygon, it give me 500 server error. It is a shame. It is impossible to use this data in production. Also, other endpoints are not working too for crypto and forex.
Here you can see the error;

I would heavily recommend having a look at FactSet APIs
Especially for accurate sector data, geographic revenue exposure, estimates, ownership, and ESG data!
Twelve API is extremely bad. So slow and it’s hard to understand their endpoints. Customer support is slow, bad, and disrespectful. I will never use it again. I’ve wasted my time and my money there. You can not build any product with them. Yahoo APIs are better.
Thanks so much for this article. It’s really helpful.
I also suggest using IXBRAnalyst to get real-time access to financial data in excel on any of your devices.
Problem with yahoo, is i get a lot of data that is just zeros, and it messes up the entire analysis.
I’m using the newsfilter.io stock market news API. They have a query and real-time stream API and an API to render article content. I’m pretty happy with their news source coverage (I’m a day- and swing-trader), much better than any brokers news feed I’ve seen so far (and I’ve seen many…..). Recently started using their Discord news bot for our trading community too. Works like a charm so far.
