# BlockRun AI Image Generation (GPT-Image)

> BlockRun AI Image Generation (GPT-Image) is a paid API for AI agents from blockrun.ai, paid per call via x402, $0.041/call, status unknown (last checked 2026-09-14).

Generates images from a text prompt using OpenAI GPT-Image models, accessible via a pay-per-call x402 gateway.

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 blockrun-ai-image-generation-gpt-image-5bb08d8c -d '<json body>'
```

Example prompt: Generate 1 image of a futuristic cityscape at night with neon lights, 1024x1024, using the openai/gpt-image-1 model.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-call image generation via OpenAI's GPT-Image models without managing an OpenAI account directly — ideal for AI agents that need on-demand image creation with crypto micropayments (x402 protocol) and no subscription overhead.

## Known failure modes

- Invalid or unsupported model ID returns an error
- Prompt violates content policy and is rejected
- Unsupported image size string causes validation error
- Network or gateway timeout for complex prompts
- Payment failure (insufficient balance or x402 auth issue) blocks the request
- n exceeds maximum allowed number of images per call

## How this service works

Image generation.

## Output

Returns generated image data (typically as URLs or base64-encoded image content) for each image requested, based on the submitted prompt, model, size, and quantity parameters.
