## 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 api-pixo-tools-pdf-compress-48c0c61e -d '<json body>'
```

Example prompt: Can you compress this PDF I'm uploading — it's too large to email and I need to shrink it down?

## When to prefer this

Use this endpoint when you need to reduce the file size of an existing PDF document. Prefer this over merge-and-compress if you are working with a single file. Choose this over image compression for PDF-specific documents. Ideal for automating document optimization pipelines where PDFs need to be emailed, stored, or transferred.

## Known failure modes

- Invalid or corrupt PDF file upload returns an error
- Non-PDF binary file submitted returns format rejection
- Network timeout for very large PDFs
- Insufficient USDC payment (x402 payment required per call)
- Empty or missing file field returns validation error

## How this service works

Compress a PDF — priced per page
