## Verdicts

**Ideogram API.** Text rendering and layout control are the model's focus. Six API incidents in 90 days, three on v3 endpoints between 23 and 29 September.

**Stability AI Image API.** Fixed price per call for every endpoint, published in credits. No new image model we could date since SD 3.5 Flash in July 2025.

## Before you call either

### Ideogram API

1. Send multipart form data, not JSON
2. Treat 402 as no credit or no payment method, and 422 as an unsafe prompt to rewrite, not retry
3. Check `is_image_safe`. When it's false the `url` is empty
4. Download images straight away, the links expire
5. Use the `/async/` variants with `webhook_url` for batches and verify the Ed25519 signature

### Stability AI Image API

1. Send `accept: image/*` to get bytes back, or `application/json` for base64
2. Stay under 150 requests every 10 seconds. A 429 locks you out for 60 seconds
3. Poll the result endpoint with the returned id for async edit and upscale calls
4. Use Stable Image Core or SD 3.5 Flash for drafts, Ultra for finals
5. Send multipart form data, not JSON
