## Verdicts

**ArtCraft.** Public source under permissive licences. No external-agent API verified.

**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

### ArtCraft

1. Use the interactive application unless an official automation interface is confirmed.
2. Check the model service terms before sending private reference media.

### 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
