## 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 document-to-markdown-converter-pdf-office-html-3a04a6a8
```

Example prompt: Can you convert the PDF at https://example.com/report.pdf into clean Markdown so I can read its headings, tables, and text?

## When to prefer this

Choose this endpoint when you need to quickly convert a document (PDF, Word, Excel, PowerPoint, HTML, CSV, or XML) into structured Markdown without setting up an account or API key. It is ideal for one-off document conversions billed at a flat per-call rate with no subscription, and is well-suited for AI pipelines that need document text with preserved structure (headings, tables) and a token count for context window planning.

## Known failure modes

- Scanned PDF with no text layer returns empty or minimal text (no OCR is performed)
- Invalid or inaccessible URL returns an error
- Unsupported file format may fail to parse
- Malformed base64 input causes a parse error
- Payment not confirmed results in no Markdown delivery (pay-per-success model)

## How this service works

Turns a document into clean Markdown in about a second: pass an https URL or base64 of a PDF, Word, Excel, PowerPoint, HTML, CSV or XML file and get the text back with its headings, tables and page markers, plus the token count. It reads the text layer, so a scanned page with no text layer comes back without text. You are only charged if the Markdown is delivered. No API key, no account.

## Output

Returns clean Markdown with the document's headings, tables, and page markers preserved, along with the token count of the extracted text. Scanned documents without a text layer will return without readable text.
