# List the designs of a building

`GET /projects/{project}/concepts`

## Request

- Base URL: `https://api.getfacade.ai/api/v1`
- URL: `https://api.getfacade.ai/api/v1/projects/{project}/concepts`
- Auth: one of:
  - HTTP bearer
  - OAuth 2 (authorization code, authorization URL `https://api.getfacade.ai/oauth/authorize`, token URL `https://api.getfacade.ai/oauth/token`, scopes: `agent`)

Renders appear in `relationships` as identifiers only, without attributes: this is where
render ids for an estimate or an album come from, not where render state is read. Poll
`GET /renders/{render}` for state; `has_main_render` says whether the design is finished.

`main_render_id` is the finished render of the main view — the render an estimate, an
album or a refine starts from. It is null until one has finished, which is exactly when
`mode: refine` would refuse it as a parent.

## Path parameters

- `project` string, required

## Response `200`

A JSON:API collection

- object
  - `data` Resource[]
    - `type` string, required
    - `id` string, required
    - `attributes` object

  - `meta` object

## Other responses

- `401`: The key is missing, revoked or expired. Re-issuing a key is a human action.
