## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability thumbnailcreator-ai-multi-model-image-generator-d39ad290 -d '<json body>'
```

Example prompt: Generate a 16:9 YouTube thumbnail for a video about 'top 10 travel hacks for budget backpackers' — I want bold text, vibrant colors, and an adventurous feel — and show me results from GPT Image 2, FLUX, and all the other models side by side so I can pick the best one.

## When to prefer this

Choose this endpoint when you need to compare multiple AI image models for thumbnail generation in a single API call, want pay-per-image pricing with no subscription, need x402/agent-native payment support, or want to give a user a side-by-side choice of AI-generated thumbnails rather than committing to one model upfront.

## Known failure modes

- Invalid or missing prompt returns an error response
- Unsupported format/aspect ratio value causes request rejection
- Payment failure via x402 protocol blocks generation
- One or more individual models may fail while others succeed, reflected per-image status
- Network timeout on long-running generations returns partial or empty image array

## How this service works

Generate YouTube thumbnails with AI image models (GPT Image, Nano Banana, FLUX, Seedream, Ideogram, Grok) side by side. Optional query: models (comma-separated ids from https://thumbnailcreator.ai/llms.txt), n (1-4 per model), format (16:9, 1:1, 9:16, 4:5). Body: {"prompt": "3-2000 characters"}. Charged only when every image succeeds.

## Output

Returns a JSON object with a generation ID, aspect ratio, status, total cost in micros, and an array of images — one per AI model — each with its own URL, model name, format, status, and individual price in micros (e.g. 167000 micros = $0.167).
