/v1/* → version retirement
Frankfurter API
Deprecated, no date
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 of these calls

In Frankfurter API's words
Deprecation and Link headers (RFC 9745) on V1 responses pointing to V2.
