## 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 x402engine-gpt-image-2-5-flare-generator-c5443ea6 -d '<json body>'
```

Example prompt: Generate a high-quality 1024×1024 image of a futuristic cityscape at sunset with neon lights reflecting on wet streets using GPT Image 2.5 Flare.

## When to prefer this

Choose this endpoint when you need a single high-quality 1024×1024 PNG from GPT Image 2.5 Flare without a monthly subscription — ideal for agents making occasional or burst image requests on a pay-per-call basis using USDC micropayments. Prefer this over subscription-based OpenAI direct access when cost isolation per call matters or when operating in an autonomous agent context without persistent API key management.

## Known failure modes

- Empty or whitespace-only prompt rejected (minLength:1, pattern \S)
- Prompt exceeding 2000 UTF-8 bytes returns validation error
- Payment failure via x402 protocol results in 402 response before generation
- Additional body fields beyond 'prompt' rejected due to additionalProperties:false
- Service unavailability or upstream GPT Image model errors returning 5xx
