exchange.io

FAQ.

Do I need an API key?
No. Public endpoints require no signup or key.
Where do rates come from?
Daily reference rates come from the European Central Bank. Non-EUR bases are derived from EUR references.
Are forecasts financial advice?
No. Forecasts are experimental statistical estimates.
How does exchange.io compare?
Unlike key-gated services such as fixer.io, exchange.io exposes no-key reference data, provenance, and history. Frankfurter is a useful upstream-style comparison; exchange.io adds forecast and operational metadata surfaces.
