## 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 agent402-tools-images-to-pdf-547bae7a -d '<json body>'
```

Example prompt: Can you combine these three images into a single PDF for me? Here are the URLs: https://example.com/photo1.png, https://example.com/photo2.jpg, and https://example.com/photo3.png — one image per page please.

## When to prefer this

Use this endpoint when you need to programmatically merge multiple PNG or JPEG images (referenced by public URLs) into a single PDF document without requiring local file handling. Ideal for agents that have already obtained public image URLs and need a ready-to-use base64 PDF in return. Prefer over client-side PDF libraries when the agent operates in a headless or serverless context without native PDF tooling.

## Known failure modes

- Invalid or inaccessible image URL — server cannot fetch one or more images, returns error
- Unsupported image format — non-PNG/JPEG URLs rejected
- Too many URLs — exceeds 20-image limit, returns validation error
- Empty URL list — request with no URLs returns validation error
- Payment failure — x402 payment not completed, request rejected
- Image download timeout — remote image server too slow, returns error

## How this service works

Combine PNG/JPEG images into a single PDF, one image per page. Body: {"urls":["https://…/1.png","https://…/2.jpg"]}. Returns the PDF as base64.

## Output

Returns a base64-encoded PDF document where each submitted image occupies one page, in the order provided. The agent must decode the base64 string to obtain the raw PDF bytes.
