# StableStudio Flux 2 Pro Image Edit

> StableStudio Flux 2 Pro Image Edit is a paid API for AI agents from stablestudio.io, paid per call via x402, $10/call, status unknown (last checked 2026-09-15).

Generates a new AI image using the Flux 2 Pro model with full control over resolution, aspect ratio, format, and safety tolerance, returning an async job ID.

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 stablestudio-flux-2-pro-image-edit-d69f068f -d '<json body>'
```

Example prompt: Use StableStudio to generate a photorealistic 4MP image of a misty mountain valley at sunrise with a 16:9 aspect ratio, PNG format at quality 95, strict safety (level 1), and use seed 42 so I can reproduce it — the prompt is 'golden morning light breaking through fog over a lush green mountain range with a winding river below'.

## When to prefer this

Choose this endpoint when you need pay-per-generation Flux 2 Pro image creation without a subscription commitment, especially when you want precise control over resolution (up to 4MP), aspect ratio, output format, and reproducibility via seed. Prefer this over subscription-based services for one-off or low-volume image generation tasks where cost-per-call pricing is more efficient.

## Known failure modes

- Missing required 'prompt' field returns a validation error
- Prompt exceeding 10,000 characters is rejected
- Invalid enum value for aspect_ratio, resolution, or output_format causes a 400 error
- Safety tolerance outside 1-5 range is rejected
- Output quality outside 0-100 range is rejected
- Payment of $10 USDC not completed results in 402 Payment Required
- Seed value outside valid integer range is rejected
- Server-side generation failure may return success:false with an error message

## How this service works

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

## Output

Returns a JSON object containing the job ID (jobId), job status ('pending'), generation type ('flux-2-pro-edit'), and a success boolean. The agent must use the jobId to poll for the completed image separately.
