## 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 openai-gpt-image-2-5-sunburst-via-mm-family-8ee04b37 -d '<json body>'
```

Example prompt: Generate a high-quality 1024x1024 image of a futuristic city skyline at sunset with vibrant orange and purple hues — use high quality and return it as a PNG.

## When to prefer this

Choose this endpoint when you need OpenAI's GPT Image 2.5 Sunburst model specifically, want to pay per call in USDC via the x402 protocol without a traditional API key subscription, and need base64-encoded image output. Prefer it over other image endpoints on the same host when Sunburst-model quality or style characteristics are required. Best for agents operating in crypto-native or x402-compatible payment environments.

## Known failure modes

- 'auto' quality value is rejected — must specify low, medium, high, xhigh, or max explicitly
- Missing or malformed prompt returns a validation error
- Payment failure if insufficient USDC balance for x402 transaction
- Prompt violates content moderation policy and is refused
- Invalid output_format or size string causes a 400 error
- Network timeout for large high-quality image generation requests

## How this service works

gpt-image-2.5-sunburst: OpenAI GPT Image 2.5 Sunburst image generation, paid per call in USDC. OpenAI list $30 per 1M image tokens (1024x1024: low 196, medium 439, high 1756 tokens), text in $5 per 1M, plus $0.0005 (Base) or $0.0005 (Solana) per call. Send size and quality (auto is refused); omitted means 1024x1024 medium. Returns b64_json. Rates: https://openai.mm.family/x402/pricing

## Output

Returns a JSON object containing an array of generated images as base64-encoded strings (b64_json), along with metadata including the image size, quality level, output format, creation timestamp, and token usage breakdown (input tokens, output tokens, total tokens).
