Field notes
The API compares eight exchange-rate sources and lets callers declare whether they are charging, paying, or seeking a neutral median through the strategy parameter. Its safeguards compare the chosen figure with a live market anchor, applying a cap or floor and exposing fields that indicate when either was triggered. The homepage lists 1,000 free calls per month, eight currency pairs, and source refreshes as fast as one minute; deeper API use appears to require an API key.
