The public API under /open/v1/* has been reorganised into clearer
namespaces. This version is the first stable shape we plan to keep for
external integrations — if you wrote code against earlier paths,
you'll need to update endpoints once; after this release the
namespaces are committed.

Breaking changes. All legacy ad / brand / image / video paths
have been removed and replaced. See Removed for the
rename table.

Added

Ad Library — global ad catalog

The /ads* endpoints moved under a single /ad-library namespace so
that "the global library" is a first-class noun, distinct from an
ad-account's own ads.

GET /open/v1/ad-library/search — full-text + filter search across
the global ad library.
GET /open/v1/ad-library/saved — ads the calling workspace has saved.
GET /open/v1/ad-library/{ad_id} — single ad detail.

Brand Library — global brand catalog

Mirror of Ad Library, for brands. Replaces /brands*.

GET /open/v1/brand-library/search — search the global brand
catalog by keyword.
GET /open/v1/brand-library/followed — brands the workspace tracks.
GET /open/v1/brand-library/{brand_id} — single brand detail.
GET /open/v1/brand-library/{brand_id}/ads — ads belonging to a
catalog brand.

Owned Brands — workspace-owned brand profiles

Promoted from /my-brands so the distinction from catalog brands is
visible in the URL. These are the brand profiles you use as brand_id
when calling the image-generation endpoints.

GET /open/v1/owned-brands — list the workspace's own brand
profiles.

Image Generations — image-gen lifecycle as a resource

The previous trio (POST /images/generate, GET /images/jobs/{id},
GET /images/{id}) is now a single image-generations resource with
nested generated-image lookups.

POST /open/v1/image-generations — submit a creative brief; returns
generation_id.
GET /open/v1/image-generations/{generation_id} — poll status;
image_ids populates once individual images are scheduled.
GET /open/v1/image-generations/{generation_id}/images/{image_id}
— fetch a single generated image's detail and URL.

Response field renames are part of the shape change:
project_id → generation_id, image_task_ids → image_ids,
concept_task_ids → concept_ids.

Video transcripts — POST + GET on the same path

Cached video transcripts now live under the owning ad-account, with
POST as the trigger and GET as the read.

POST /open/v1/ad-accounts/{account_id}/videos/{video_id}/transcript
— trigger transcription (synchronous; consumes credits on cache
miss).
GET /open/v1/ad-accounts/{account_id}/videos/{video_id}/transcript
— cache-only lookup; never triggers, never charges credits. Returns
404 when no transcript is cached yet.

Pick the verb by intent — same path, different cost.

Changed

Unchanged namespaces

These endpoints were already well-named and stayed put across the
0.2.0 rename pass — no client changes required:

/open/v1/boards* — board list / detail / contained ads
/open/v1/ad-accounts* — list / summary / per-ad performance

Removed

Legacy paths removed in 0.2.0. Each row tells you what to call instead.

`GET /open/v1/videos/{video_id}?account_id=…`	`GET /open/v1/ad-accounts/{account_id}/videos/{video_id}/transcript`

Migration notes

Search-and-replace the path prefixes from the Removed
table.
If you parse image-generation responses, rename:
- project_id → generation_id
- image_task_ids → image_ids
The single-image fetch is now keyed on (generation_id, image_id)
instead of a flat image_task_id — update any client that stored
only the flat id; it's still present as the id field on each
generated-image response.
For video transcripts: pass account_id as a path parameter (not a
query parameter or body field) and pick POST vs GET deliberately —
POST charges on cache miss, GET never does.
