FAQ

Does FXpeek have a no-key exchange-rate API?

FXpeek provides lightweight public examples for supported reference-rate endpoints.

When should I upgrade from free API use?

Upgrade when you need production volume, commercial delivery, broader coverage, or repeated data packages.

Can Google Sheets use the free API?

Google Sheets should use the CSV endpoint with IMPORTDATA for simple imports.

Is the free API a trading API?

No, FXpeek provides reference data, not order execution, broker quotes, or trading signals.

Important limitations

FXpeek provides historical reference data, not bank quotes, settlement quotes, tax authority rates, accounting authority rates, legal advice, or trading signals.
Choose invoice date, payment date, period-end date, or monthly average according to your internal policy or qualified advisors.
Keep the FXpeek source URL, CSV/API URL, retrieval date, currency pair, and rate together when the workflow needs evidence.
