enum<string>
default:2026-05-01

Calendar-dated API version pin. New integrations should pin 2026-05-01 to opt into the newest response shapes. For back-compat the server also accepts requests with no header and resolves them to the current default (today: 2026-04-12); that default advances on each sunset date. Any unsupported value returns 400 unsupported_version.

Available options:
2026-04-12,
2026-05-01
Example:

"2026-05-01"
