# OpenAI Image Generation via mm.family (x402)

> OpenAI Image Generation via mm.family (x402) is a paid API for AI agents from openai.mm.family, paid per call via x402, $0.003473/call, status unknown (last checked 2026-10-02).

Generates images from text prompts using OpenAI image models (gpt-image-1, gpt-image-2, gpt-image-2.5, etc.), paid per call in USDC via x402 protocol, returning base64-encoded PNG/JPEG/WebP.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-image-generation-via-mm-family-x402-375bc3fb -d '<json body>'
```

Example prompt: Generate a photorealistic image of a golden retriever sitting in a sunlit meadow — use gpt-image-2, 1024x1024, medium quality, and return it as a PNG.

## When to prefer this

Choose this endpoint when you need OpenAI-quality text-to-image generation (gpt-image-1, gpt-image-2, gpt-image-2.5 family) and want to pay per call in USDC via the x402 protocol without managing OpenAI API keys directly. It is especially useful for autonomous agents that need crypto-native micropayments for image generation, or when you want access to multiple OpenAI image model variants (including mini and latest aliases) through a single proxy with transparent per-call pricing.

## Known failure modes

- Invalid or missing 'quality' parameter (auto is refused — must specify low, medium, high, xhigh, or max)
- Unsupported model key returns 404 or validation error
- Payment failure or insufficient USDC balance blocks request with 402
- Prompt violates content moderation policy, returning a refusal or error
- Invalid size string format causes a schema validation error
- Requesting 'n' greater than supported count for the chosen model

## How this service works

OpenAI image generation (gpt-image-2.5, gpt-image-2, gpt-image-1.5, gpt-image-1, gpt-image-1-mini, chatgpt-image-latest), paid per call in USDC. OpenAI list rates per 1M image tokens (1024x1024 low = 196 tokens on gpt-image-2), plus $0.0005 (Base) or $0.0005 (Solana) per call. Send size and quality (auto is refused); omitted means 1024x1024 medium. Returns b64_json. One endpoint per model: /x402/v1/models/<key>/images/generations. Rates: https://openai.mm.family/x402/pricing

## Output

A JSON object containing a data array with one or more base64-encoded images (b64_json), along with metadata including the image size, quality setting, output format, token usage (input, output, total tokens), and a creation timestamp.
