## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-pdf-merge-fa727f3e -d '<json body>'
```

Example prompt: Can you merge these two PDFs into one — https://example.com/report.pdf and https://example.com/appendix.pdf — and give me a link to the combined file?

## When to prefer this

Choose this endpoint when an agent needs to programmatically merge two or more PDFs into a single hosted file and receive a stable URL back, especially in automated workflows where USDC micropayment via x402 is already supported. Ideal for document assembly tasks such as combining reports, invoices, or multi-part submissions without spinning up server-side PDF tooling.

## Known failure modes

- One or more input PDF URLs are unreachable or return non-PDF content — endpoint may return an error or produce a corrupted output
- Payment of $0.01 USDC via x402 is not included or fails — request is rejected before processing
- Input URLs point to password-protected or encrypted PDFs that cannot be parsed
- Too many PDFs or total file size exceeds server limits — likely returns a size/count limit error
- Malformed request body missing required PDF URL list — returns validation error

## How this service works

Paid x402 endpoints organized into product clusters. USDC-settled on Base. MCP-callable. ERC-8004 identity registry agentId 47167.

## Output

A JSON object containing a `pdf_url` field with a hosted URL pointing to the merged PDF file, and a `merged_count` integer indicating how many PDFs were combined.
