# Presign a brand kit's inspiration exemplar frames

`POST /v1/brand-kits/{id}/exemplars`

## Request

- Base URL: `https://api.cueframe.ai`
- URL: `https://api.cueframe.ai/v1/brand-kits/{id}/exemplars`
- Auth: one of:
  - HTTP bearer
  - OAuth 2 (authorization code, authorization URL `https://api.cueframe.ai/api/auth/mcp/authorize`, token URL `https://api.cueframe.ai/api/auth/mcp/token`, scopes: `projects:read`)
  - API key in header `PAYMENT-SIGNATURE`

Returns short-lived URLs for the kit's exemplar frames (the pixels the maker and judge condition on). Filter to one motif's evidence frames with `motifId`. Vision-budget-bounded consumers should keep `limit` small (default 6).

## Path parameters

- `id` string, required

## Request body

- BrandKitExemplarsRequest: POST /brand-kits/{id}/exemplars body — select which exemplar frames to presign.
  - `motifId` string
  - `limit` integer

## Response `200`

Presigned exemplar frames.

- BrandKitExemplarsResponse
  - `exemplars` object[], required
    - `index` integer, required
    - `url` string, required
  - `contactSheetUrl` string

## Other responses

- `400`: Bad request — validation_error / invalid_cursor / invalid_query.
- `401`: Missing or invalid Authorization header.
- `402`: Payment required. Returned when the caller presents no API key on a priced operation: the body AND the `Payment-Required` header carry the x402 v2 challenge (accepted scheme, network, USDC asset, amount, payTo). Sign the EIP-3009 authorization and retry with a `PAYMENT-SIGNATURE` header. A KEYED caller sees this status instead when their plan lacks or has exhausted the feature (`billing_required`).
- `403`: Forbidden — permission insufficient.
- `404`: Resource not found.
- `422`: Unprocessable — invalid_composition / media_in_use / session_in_use / render_not_cancellable.
- `429`: Rate limited. Retry-After header present.
- `500`: Internal error.
