## 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 tanod-pdfpeek-document-to-markdown-converter-481f72c2 -d '<json body>'
```

Example prompt: Can you convert this PDF at https://example.com/report.pdf to Markdown so I can work with the text content?

## When to prefer this

Choose this endpoint when you need to convert any of the major office or document formats (PDF, DOCX, XLSX, PPTX, HTML, EPUB, CSV) to clean Markdown, especially when the document is publicly accessible via URL or available as a base64 payload. Prefer it over generic OCR or text extraction services when structured Markdown output (headings, tables, lists) is needed rather than raw text.

## Known failure modes

- Document URL is private, internal, or IP-literal — returns refusal error
- File exceeds 20 MB via URL or 10 MB via base64 — returns size limit error
- Unsupported or corrupted file format — returns parsing error
- URL is unreachable or returns non-200 status — returns fetch error
- base64 string is malformed or exceeds maxLength — returns validation error
