Coinbase Exchange Rates API
Coinbase public exchange rates API with no key: convert any cryptocurrency to 100+ fiat currencies in a single request. Tested curl example and live JSON.
Endpoint tested and returned HTTP 200 on 19 Aug 2026
What is the Coinbase Exchange Rates API?
The Coinbase exchange rates API is a free public endpoint that returns conversion rates from one cryptocurrency or fiat currency into more than 100 others in a single request, with no API key required.
This endpoint is unusually convenient: one request returns rates from your chosen base currency into every currency Coinbase knows about, crypto and fiat alike. Where most APIs make you specify target currencies, Coinbase just gives you the whole table.
That makes it ideal for a currency selector where the user can pick any target — you fetch once, cache the map, and convert locally without another network call per selection.

Coinbase Exchange Rates API — frequently asked questions
Does the Coinbase exchange rates API require an API key?
No. The public /v2/exchange-rates endpoint works with no key or authentication. Only account and trading APIs require credentials.
What currencies does it support?
Over 100 fiat currencies plus the cryptocurrencies Coinbase lists. One request returns rates into all of them from your chosen base.
Are the rates returned as numbers?
No, they are strings to preserve precision. Convert them explicitly, and prefer decimal arithmetic for any monetary calculation.
How often do the rates update?
Continuously, tracking market movement. For display purposes caching for 30-60 seconds is normally acceptable and avoids the rate limit entirely.
