The public jobs API uses URL major versions beginning with /api/v1. v1 is additive-only. A breaking change requires a new major path such as /api/v2.
There is no scheduled deprecation. When an operation or field is retired, responses will include RFC 9745 Deprecation and Sunset headers and this page will name the date.
There is no apply-via-agent. Callers must send candidates to click_url (the LexGO page with tracking). Rehosting the corpus or applying on a candidate's behalf is not permitted.
