API expectations
Why is the FXpeek API free, and what are its limits?
What the public examples are for, how responsible use works, and when to request a managed data workflow.
Short answer
FXpeek keeps lightweight public examples available for lookup, prototypes, spreadsheets, and evaluation. No fixed public daily allowance is promised on this page; abusive or high-volume traffic may be limited, and production users should monitor responses and request a managed workflow when continuity matters.
Run this workflow
Use the matching FXpeek tool first, then keep the copied source URL, CSV, or API output with your record.

Is unlimited access guaranteed?
No. FXpeek does not promise unlimited public traffic and may limit abusive or high-volume requests.
How can integrations reduce load?
Cache historical results, request only needed ranges, and avoid repeatedly polling unchanged dates.
Reference note
The free surface is an evaluation and lightweight workflow layer, not an unlimited-service guarantee.
