# Domain lookup (deprecated)

`GET /api/registry/lookup/domain/{domain}`

> **Deprecated.**

**Deprecated.** Use `/api/registry/publisher?domain=X` for richer data including hosting state, per-agent rollup, and brand.json fallback. This endpoint will be removed in a future release.

## Path parameters

- `domain` string, required

## Response `200`

Domain lookup result

- DomainLookupResult
  - `domain` string, required
  - `authorized_agents` object[], required
    - `url` string, required
    - `authorized_for` string
    - `member` object
      - `slug` string
      - `display_name` string
      - `membership_tier` string — Raw AAO membership tier enum (e.g. `individual_professional`, `company_leader`). Present only when the profile owner has set their member card to public (`is_public=true`) AND the org has a resolvable tier. Absent for private profiles and for orgs without an active tier-bearing subscription.
      - `membership_tier_label` string — Human-readable label for `membership_tier` (e.g. `Professional`, `Partner`, `Leader`). Matches the AAO pricing page. Use this for UI display; the raw enum is for programmatic gating. Presence rules match `membership_tier`.
      - `is_founding_member` boolean — True when the profile owner carries the Founding Member badge (joined before the founding-cohort cutoff). Surfaced when the profile owner has set their member card to public (`is_public=true`). Absent for private profiles. Founding Member is orthogonal to tier — founding orgs typically display both (e.g. Scope3 shows `Partner` + `Founding Member`).
  - `sales_agents_claiming` object[], required
    - `url` string, required
    - `member` object
      - `slug` string
      - `display_name` string
