## Which one, for what

### Bria API (B)

Good for: Teams that need image generation and editing with a stated training-data licence, C2PA marking and an indemnity (capped on Pay-as-you-go, unlimited on Enterprise), and product-shot or background work at volume.

Ahead on:
- Reliability, 83 against 0
- Schema & documentation, 84 against 25
- Agent ergonomics, 76 against 0
- Security & auth, 33 against 0
- Payments & pricing, 40 against 0
- Maintenance & community, 69 against 5

Also in its favour:
- Still running. Google Imagen has shut down
- Runs on your own machine
- No incidents deducted, where Google Imagen loses 3 points for them

Watch for: API keys are organisation-wide with no scopes, and no spend cap was found in the reviewed documentation

### Google Imagen (F)

Good for: Nothing new. It shut down on 2026-08-17.

Ahead on:
- Transparency & trust, 60 against 49

Watch for: Discontinued. Calls to imagen model names fail on both the Gemini API and Vertex AI

## Verdicts

**Bria API.** Per-image prices, 100 free calls without a card, OpenAPI files and Markdown docs make a first call quick, and the terms warrant that customer content is not used for training. Keys are organisation-wide with no scopes, and the API has no changelog or deprecation policy.

**Google Imagen.** Shutdown dates were published in the Gemini API changelog and the Vertex AI release notes, with replacements named. Discontinued. Calls to imagen model names fail on both the Gemini API and Vertex AI.

## Before you call either

### Bria API

1. Send the key in the `api_token` header, not as `Authorization: Bearer`. Only `/v2/image/verify` and `/v2/video/verify` work without it
2. Expect `202` with `request_id` and `status_url` from v2 endpoints. Poll `GET /v2/status/{request_id}` every 1 to 2 seconds, or pass `sync: true`
3. Status polls count towards the per-endpoint limit (10 a minute on Free, 60 on Pay-as-you-go), so prefer `webhook_url` for batches
4. Download results promptly. Image URLs expire after 3 days by default, and legacy `/v1/product/*` results after 1 hour
5. Do not resend a failed `POST` blindly. There is no idempotency key, and the SDKs retry status polls only

### Google Imagen

1. Replace `client.models.generate_images` with `client.models.generate_content` and a `gemini-3.1-flash-image` model
2. Read images from the response content parts, not from `generated_images`
3. Don't budget from the Vertex Imagen price rows, they describe a retired product
4. If the job needs a mask-based inpaint, use another vendor's fill endpoint, since Gemini image editing is prompt-based
