notes: >-
  Public access uses a single Bearer API key (keys are prefixed `sk-`), passed in the
  `Authorization: Bearer $SURF_API_KEY` header, generated from the dashboard at
  agents.asksurf.ai. The OpenAPI also declares AdminToken (X-Admin-Token) and InternalKey
  (X-Internal-Key) apiKey schemes that are internal/admin-only and not for public consumers.
  The gateway also serves 30 free credits per day per IP with no key at all.
