# PayWeave Replicate – FLUX 2 Max Image Generation

> PayWeave Replicate – FLUX 2 Max Image Generation is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.45/call, status unknown (last checked 2026-09-14).

Generates high-quality images from text prompts using Black Forest Labs' FLUX 2 Max model via a pay-per-call API.

## Facts

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 payweave-replicate-flux-2-max-image-generation-3fc5f86f -d '<json body>'
```

Example prompt: Use FLUX 2 Max on Replicate to generate a photorealistic image of a futuristic cityscape at sunset with neon lights reflecting off wet pavement.

## When to prefer this

Choose this endpoint when you specifically need FLUX 2 Max, Black Forest Labs' highest-quality flagship image generation model, via a simple pay-per-call (x402/USDC) interface without needing a Replicate account or subscription. Ideal for agents that need to generate premium-quality images on demand and can pay per inference in crypto.

## Known failure modes

- Model inference failure returns status 'failed' with a non-null error message
- Payment failure (402) if USDC balance is insufficient — call is rejected before running
- Invalid or missing 'input' object returns a 400-level error
- CDN URL expires after ~24 hours making the output image inaccessible
- Status may return 'processing' or 'starting' if the model is cold-starting, requiring polling
- Canceled status if prediction is manually stopped mid-run

## How this service works

Run open-source AI models — image, video, audio.

## Output

Returns a Replicate prediction object containing a CDN-hosted image URL (valid ~24 hours), a prediction ID, status (succeeded/failed/canceled/processing/starting), timing metrics (total_time, predict_time), the model name, and the USD amount charged for the call.
