## 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-merge-compress-95c3535c -d '<json body>'
```

Example prompt: Merge these 4 PDF files I'm uploading into a single document and compress the result so it's smaller — I want one combined, compressed PDF back.

## When to prefer this

Use this endpoint when you need to both merge multiple PDFs and compress the result in a single API call, saving a round-trip compared to calling separate merge and compress endpoints. Ideal for automated document workflows where file size matters and you want a bundle rate per page. Prefer this over the plain merge endpoint when output file size reduction is also a goal.

## Known failure modes

- Fewer than 2 PDF files provided — returns 400 error
- More than 20 PDF files provided — returns 400 error
- One or more uploaded files is not a valid PDF — returns 400 or 422 error
- Payment not provided or insufficient — returns 402 Payment Required
- Files too large or total page count too high — may return 413 or timeout
- Corrupted or password-protected PDF files may fail to merge

## How this service works

Merge PDFs and compress the result in one call — priced per total page across all inputs (bundle rate)
