# /v1/* is deprecated

Frankfurter API deprecated /v1/* without giving a shutdown date yet.

The Frankfurter API deprecated the /v1/* endpoints without a shutdown date, announcing the change on September 9, 2026. Calls to these endpoints will eventually fail, with responses currently returning Deprecation and Link headers pointing to V2.

## What to use instead

Migrate your calls to /v2/rates, where symbols becomes quotes and rates are returned as an array of {date, base, quote, rate}. Alternatively, call /v2/rate/{base}/{quote}.
