Free Currency Exchange Rates API with 150+ Currencies & No Rate Limits.

Strengths

Exchange rates for 144 currencies with daily history back to the 1990s, English and Arabic.

Free currency-rates JSON API and an embeddable converter widget from Fulusly.

Strengths

Prototyping or a tutorial? Pick the one that needs no API key (both qualify).
Calling from a web page? You need CORS. Otherwise route requests through your own server or a serverless function.
Going to production? Favour HTTPS, a strong uptime record and a provider with clear rate limits and terms. Check each API's docs before you commit.
Still unsure? Both are free to try: send one request to each and compare the data you get back.

Neither needs an API key; you can call both straight away.
