## 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 fastapi-online-image-rotate-244786cc -d '<json body>'
```

Example prompt: Can you rotate this image 90 degrees clockwise and expand the canvas so nothing gets cropped?

## When to prefer this

Choose this endpoint when you need a simple, pay-per-call image rotation with no signup or subscription required. Ideal for agents that occasionally need to fix image orientation programmatically without integrating a full image editing SDK. At $0.001 USDC per call it is extremely cost-effective for low-to-moderate volume tasks.

## Known failure modes

- Unsupported file format returns an error — only PNG, JPEG, and WebP are accepted
- Invalid degrees value (non-numeric or out-of-range) may return a 422 validation error
- File too large may result in timeout or rejection
- Missing required file parameter returns 422 Unprocessable Entity
- Payment failure (insufficient USDC or invalid x402 header) returns 402 Payment Required

## Output
