````yaml GET /links/random
openapi: 3.1.0
info:
  title: Reqlick API
  description: >-
    REST API for Reqlick — link shortening, QR codes, file-to-link, custom
    domains and analytics.


    Authenticate with a workspace API key (`Authorization: Bearer rqk_...`),
    created under Settings → API Keys.


    A key is scoped to the single workspace it was created in. Using it against
    a different workspace returns 403, even when the owning user is a member of
    both.


    API access requires a paid plan.
