# GEDX402 Flux-1-Schnell Image Generation

> GEDX402 Flux-1-Schnell Image Generation is a paid API for AI agents from image.gedx402.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Generates images from text prompts using the Flux-1-Schnell diffusion model, payable with USDC on-chain via x402 protocol — no API keys required.

## 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 gedx402-flux-1-schnell-image-generation-95d8a205
```

Example prompt: Generate an image of a futuristic city skyline at sunset with neon lights reflecting on wet streets, 1024 pixels wide by 768 pixels tall, using 20 diffusion steps for maximum quality.

## When to prefer this

Choose this endpoint when you need fast, cost-effective AI image generation (Flux-1-Schnell) without managing API keys or subscriptions, and you can pay per-call with USDC on Base, Polygon, Arbitrum, World, or Solana via the x402 protocol. Ideal for agents that need on-demand image generation with crypto micropayments.

## Known failure modes

- Payment not provided or insufficient USDC — HTTP 402 returned requiring x402 payment
- Prompt missing from request — likely 400 or empty/error response
- num_steps out of range (must be 1–20) — validation error
- Width or height values unsupported by the model — may return an error or fall back to defaults
- Network timeout if diffusion inference takes too long
- On-chain payment confirmation delays causing request failure

## How this service works

Flux schnell text-to-image — fast generation, one x402 payment per image.

## Output

A JSON object containing a single field 'image' whose value is a base64-encoded string of the generated image. The agent can decode this to display or save the image.
