## 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 amnt-gpt-image-1-5-medium-text-to-image-f5fc70c7 -d '<json body>'
```

Example prompt: Can you draw me a flat-art fox mascot waving, clean simple shapes, on a transparent background — I need it as a 1024x1024 PNG?

## When to prefer this

Choose this endpoint when you need a fast, affordable ($0.039) medium-quality flat-art image — logos, icons, or stickers — at 1024x1024 with optional transparency. Prefer over the Low tier when quality matters more than cost, and over the High tier when speed and price are priorities. Best suited for clean, simple vector-style art rather than photorealistic or highly detailed scenes.

## Known failure modes

- Prompt too long (over 1000 characters) returns a validation error
- Invalid format enum value causes a schema error
- JPEG compression value out of 0–100 range returns an error
- Payment failure or insufficient USDC balance blocks the request
- Model timeout after ~15s if inference is slow
