## 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 x402-agentutility-ai-flux-2-pro-image-generator-2727aa93 -d '<json body>'
```

Example prompt: Generate a photorealistic image of a misty mountain lake at sunrise with pine trees reflected in the water, using the Flux 2 Pro model.

## When to prefer this

Choose this endpoint when you specifically need Venice's flux-2-pro model and want a fixed, predictable route without model selection overhead. Prefer it over generic image-generate-pro when you know Flux 2 Pro is the target model, need a stable dedicated endpoint for automation, or want the cost certainty of a single $0.04 per-call price. Also ideal when the downstream consumer expects a permanent fal-hosted PNG URL directly.

## Known failure modes

- Invalid or missing prompt — returns an error indicating the required text prompt is absent
- Prompt flagged as NSFW — endpoint only supports SFW content and will reject adult or prohibited content requests
- Payment failure — x402 USDC payment not confirmed on Base, request rejected before generation
- Model unavailability — upstream Venice/fal service outage returns a 5xx error
- Malformed request body — missing required fields returns a 400-level validation error

## How this service works

Generates SFW images with Venice's flux-2-pro model on a dedicated endpoint. Fixed-model route for buyers searching specifically for Flux 2 Pro / FLUX.2 Pro image generation; use image-generate-pro when you want a selectable premium model tier. Returns a permanent fal-hosted PNG URL.

## Output

A permanent fal-hosted PNG image URL pointing to the generated image. The response contains a direct link to the rendered output that can be embedded or shared without expiration concerns.
