What are the reliable crypto price APIs, preferably that operate as a hidden service?

Hello. I hope this is an appropriate place to post this question. If not, does anyone know of any subtforums that are more about building and maintaining hidden services?

I am in need of a high volume API that I can call on to provide crypto/fiat prices. Using it can't require me to provide KYC or a credit card. Free is preferable, but crypto payments would work.

Obviously all onion markets and most other services have this. Can anyone point me to which APIs people are using for this?

Please send me a message if you would rather do that then post it publicly.

Thank you for your time.

Use the Feather wallet websockets which retrieve information from CoinGecko and CurrencyScoop.

Thank you, that's exactly the information I was looking for.

Use your brain. Connect to it using a websocket connection and see what type of data you get in return.
