Historical FX Data — FAQ.

The details developers ask about before integrating.

How do I get historical currency rates?
Call /historical for a single date or /time-series for a range — both are historical currency rates API calls for any supported pair, daily, on every plan. For hourly and minute data, use the FX endpoints on Premium.
How is time-series metered?
One time-series request counts as one API call against your 1,000,000 monthly allowance — regardless of the date range returned.
How far back does each pair go?
Start dates vary by pair — majors reach back to 1970, others start later. Coverage metadata is available via the API and docs.
What formats are supported?
JSON over HTTPS, consistent with every other fastFOREX API endpoint. Time-series endpoints accept ISO 8601, unix and UTC datetimes with timezone offsets — responses mirror the format you send.
Which endpoint gives which granularity?
The currency /historical and /time-series endpoints are daily. Hourly and minute history live on the FX endpoints: /fx/ohlc/time-series and /fx/quote/time-series (Premium).
