## 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`):

## When to prefer this

Choose this endpoint when you need OpenAI's latest chatgpt-image-latest model specifically, want per-call USDC micropayment billing via x402 (no subscription required), and need base64-encoded image output directly in the response. Prefer it over alternatives when you want fine-grained quality control (low/medium/high) and format selection (PNG/JPEG/WebP) with transparent token-based pricing.

## Known failure modes

- Prompt refused by moderation (content policy violation) — returns error response
- 'auto' quality value rejected — must specify 'low', 'medium', or 'high' explicitly
- Missing or invalid USDC payment via x402 — returns 402 Payment Required
- Invalid output_format value — must be 'png', 'jpeg', or 'webp'
- Model field must be set to 'chatgpt-image-latest' exactly — other values rejected
- Overly long or malformed prompt may cause generation failure or truncation
