what is the most reliable and "easy to integrate with" API for getting currency exchange rates?

My project needs to gather currency exchange rates at regular intervals. Looking for a free or low-cost API with low latency that can provide up to date data.

Actually never mind, that only updates once per day.

Yeah, it updates only once.

I'm going with for now. Would love to learn about any other better service if anyone knows. Thank you.

Checkout on which API Find Exchange is made (… ). It updates every 3 seconds.
