# Serve an uploaded e-mail signature image

`GET /v1/branding/{accountId}/signature`

## Request

- Base URL: `https://api.briefgate.dev`
- URL: `https://api.briefgate.dev/v1/branding/{accountId}/signature`
- Auth: none required

Public, no authentication: this is the address client-facing emails embed. Always `image/png`, cached as immutable — every upload gets a new `?v=` so a replaced signature never comes back from a cache.

## Path parameters

- `accountId` string, required

## Response `200`

The signature image

## Other responses

- `404`: The account has no uploaded signature image.
