## 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-blur-b0895834 -d '<json body>'
```

Example prompt: Can you blur this image file for me with a radius of 10?

## When to prefer this

Choose this endpoint when you need a simple, cheap ($0.001 USDC), no-signup image blur operation accessible via a pay-per-call crypto model. Ideal for agents that occasionally need to blur images without maintaining an account or subscription with a larger image-processing SaaS. Works well for privacy redaction, background softening, or aesthetic blur filters on PNG, JPEG, or WebP files.

## Known failure modes

- Unsupported file format (non-PNG/JPEG/WebP) returns an error
- Missing or invalid image file returns a 400 error
- Radius value not parseable as a number may cause a processing error
- File too large may result in a timeout or rejection
- Payment not included or insufficient USDC causes a 402 response

## Output

A blurred version of the submitted image file, returned as binary image data. The degree of blurring is controlled by the radius parameter — larger values produce stronger blur effects.
