## 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 agentutility-merge-pdf-134358f0 -d '<json body>'
```

Example prompt: Can you merge these two PDF files into one — my invoice.pdf and receipt.pdf — and give me a link to download the combined document?

## When to prefer this

Use this endpoint when an agent needs to programmatically combine multiple PDF documents into one, paid per-call with USDC at $0.01 via the x402 protocol — ideal for document automation workflows where merging invoices, reports, or contracts is needed on demand.

## Known failure modes

- Invalid or inaccessible PDF URLs result in an error
- Non-PDF file types rejected
- Payment failure via x402 blocks the request
- Corrupted or password-protected PDFs may fail to merge
- Too many or too large files may exceed limits

## How this service works

## Output
