## 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 independent-image-api-gateway-gpt-image-2-5-sunburst-495bfc21 -d '<json body>'
```

Example prompt: Generate an image of a minimalist lighthouse at dawn with soft pastel colors and clean line-art style — pay per image using USDC on Base.

## When to prefer this

Choose this endpoint when you need one-off or low-volume AI image generation without committing to a subscription, especially in crypto-native or agent workflows that already use USDC on Base for payments. It is particularly well-suited for AI agents that need to autonomously pay per image using the x402 protocol. Prefer this over subscription-based image APIs when cost predictability per image ($0.08 flat) is important, or when your infrastructure is already integrated with Base chain payments.

## Known failure modes

- Payment failure: insufficient USDC balance on Base network returns 402 Payment Required
- Invalid or empty prompt returns 400 Bad Request
- Model unavailability or upstream API error returns 500 or 503
- Rate limiting or quota exceeded returns 429
- Malformed request body returns 400 with validation error

## How this service works

Independent pay-per-image text-to-image gateway. Fixed price per image, USDC on Base.

## Output

A JSON object containing a data array with one entry per image. Each entry includes b64_json (a base64-encoded PNG of the generated image) and a revised_prompt string (the model's reinterpretation of the input prompt). The top-level object also includes a created Unix timestamp.
