Get the current video thumbnail

GET

/videos/{videoId}/thumbnail

curl --request GET \
  --url 'https://api.braiv.co/v1/videos/vid_01JZ8M6A/thumbnail?includeBytes=false' \
  --header 'Authorization: Bearer <token>'

• Braiv Public API

Returns the library video’s current thumbnail (the image shown as posterUrl on GET video). GCS and Firebase Storage objects are returned as a fresh 30-minute signed URL. Public CDN URLs (for example Mux images) are returned as stored.

This is not thumbnail generation history — use GET /videos/{videoId}/thumbnails for AI generation jobs.

Hosted MCP braiv_get_current_thumbnail returns the URL unredacted and, by default, JPEG/PNG/WebP bytes so agents can save the file. Required scope: videos:read.

Parameters

Path Parameters

required

string

>= 1 characters

Braiv library video document ID.

Example

Query Parameters

includeBytes

boolean

When true, include contentBase64 (JPEG, PNG, or WebP, 8MB max) so clients that cannot follow storage URLs can still save the image. Defaults to false on HTTP. Hosted MCP requests this by default.
