## Verdicts

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

**Leonardo.Ai API.** Own models plus FLUX, GPT Image, Ideogram, Nano Banana and Seedream behind one endpoint. No per-image price list outside the logged-in calculator.

## 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.

### Leonardo.Ai API

1. Use `POST /api/rest/v2/generations` with a `model` name such as `lucid-origin`
2. Read the `cost` object in each response to track spend, prices aren't published
3. Send `quality`, not `mode`. `mode` was retired on 2026-05-04
4. Set a webhook callback URL on the key instead of polling long jobs
5. Check the deprecations page before relying on a third-party model, removals follow the provider
