Finance APIs
What are the Finance APIs on upAPI?
upAPI’s Finance category has 2 public APIs: Convert Currency and Get Crypto Prices. Each is a single HTTP POST to api.upapi.io with an X-Api-Key header and returns JSON. They share one API key and one pooled monthly quota with every other upAPI operation, so there is no separate signup or billing per provider.

How do I call a Finance API?
Send an HTTP POST to api.upapi.io followed by the operation slug (for example api.upapi.io/crypto-price.get), with your key in the X-Api-Key header and a JSON body. Any HTTP client works the same way: curl, requests in Python or fetch in JavaScript. Each operation’s page lists its input fields, its output fields and a runnable example.
How much do the Finance APIs cost?
Every Finance operation costs 1 weighted unit per call. Every unit draws from one pooled monthly quota shared across the whole catalog. See upapi.io/pricing for what a unit costs on each plan.
Is there a free tier for the Finance APIs?
Yes. The Free plan costs nothing and includes 1,000 weighted units a month across every public operation, so you can try these on real inputs before choosing a paid plan.
