## 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 stablestudio-flux-2-max-edit-c775c08a -d '<json body>'
```

Example prompt: Use StableStudio's Flux 2 Max edit to take my product photo and replace the plain white background with a warm sunset beach scene, keeping the product itself exactly as-is.

## When to prefer this

Choose this endpoint when you need to edit or modify an existing image (rather than generate from scratch) using the high-quality Flux 2 Max model, and prefer pay-per-use pricing with no subscription commitment. Ideal for one-off or low-volume editing tasks where cost predictability matters.

## Known failure modes

- Payment failure or insufficient USDC balance — returns payment error before job is queued
- Invalid or missing source image — returns 400 or validation error
- Unsupported image format or size — job may fail after submission
- Job processing timeout — status remains pending indefinitely
- Rate limiting or capacity issues — job not accepted

## How this service works

Pay-per-generation AI image and video creation. No subscriptions ever.

## Output

A JSON object containing the job type ('flux-2-max-edit'), a unique jobId (e.g. 'cmpbmzaee000j04jrzx4f43tw'), a status field (initially 'pending'), and a success boolean. The agent must poll or wait for job completion to retrieve the final edited image URL.
