## 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 agentshelf-syntexa-ch-pdf-to-markdown-converter-5e83760b -d '<json body>'
```

Example prompt: Can you extract the text from this PDF and give it to me as markdown? Here's the URL: https://example.com/report.pdf

## When to prefer this

Use this endpoint when you need to extract readable text from a PDF document — either from a public URL or as a base64-encoded file — and want the output in Markdown format. Prefer the free sandbox endpoint (POST /v1/sandbox/pdf-to-md) for testing. Choose this paid endpoint for production use or when the sandbox is unavailable.

## Known failure modes

- URL is not publicly accessible or returns a non-PDF content type
- PDF exceeds the 8MB base64 cap (~11MB encoded)
- URL triggers SSRF protection (private IP ranges, localhost, internal hostnames)
- Malformed or encrypted PDF that cannot be parsed
- Payment of exactly $0.01 USDC not included or rejected

## How this service works

Call when an agent needs text extracted from a public PDF URL (SSRF-safe) or pdf_base64 (8MB cap) as markdown. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/pdf-to-md first.

## Output

A Markdown-formatted string containing the extracted text and structure from the PDF, preserving headings, paragraphs, and lists where detectable.
