  title: Cosmose AI Deal Hunter Registration Forget Me Controller API
  description: Public registration, onboarding, invitation and account-lifecycle API behind Cosmose AI's KaiKai / Deal Hunter consumer app and its merchant and school lead-capture forms. Harvested verbatim from the provider's live springdoc endpoint at https://api.sg.cosmose.co/deal-hunter-registration-api/v3/api-docs; the only change in this refined copy is the servers[] block, which upstream advertises the internal cluster service name http://deal-hunter-registration-api/deal-hunter-registration-api instead of the reachable public gateway. See overlays/cosmose-ai-deal-hunter-registration-api-overlay.yaml for the exact delta.
