Currency Exchange — entry 007 of 18
Currency-api
This free, no-key currency API covers 200+ fiat currencies plus common cryptocurrencies and metals, served off jsDelivr's CDN with a Cloudflare Pages fallback and refreshed daily via GitHub Actions — there's no rate limit because there's no backend server to overload. The original fawazahmed0/currency-api repository has been migrated to fawazahmed0/exchange-api as its new home, though the CDN-hosted JSON endpoints (addressable by date or "latest") work exactly the same way for existing integrators.
This keyless currency API (now homed at fawazahmed0/exchange-api) serves 200+ fiat currencies plus crypto and metals as static JSON files off jsDelivr's CDN, refreshed daily via GitHub Actions with no server and no rate limit.

Gotchas & limits
- Currency selection is path-based, not a query param — swap the base currency by changing the filename, e.g. `/v1/currencies/eur.json`, not `?base=eur`
- jsDelivr is the primary CDN, but it does have occasional outages — the docs recommend a fallback to the Cloudflare Pages mirror at `https://{date}.currency-api.pages.dev/v1/...`
- Use `@latest` (or a `YYYY-MM-DD` date) in the URL for the version segment — pinning to a stale date will keep serving that day's rates instead of updating
