## 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 apiosk-talk-to-pdf-q-a-url-38e27cea -d '<json body>'
```

Example prompt: I have a PDF at https://example.com/annual-report-2024.pdf — can you tell me what the total revenue was for Q3 2024 based on the document?

## When to prefer this

Use this endpoint when you have a publicly accessible PDF URL and need to answer a specific natural-language question about its contents without manually parsing or downloading the file. Prefer this over generic web scraping endpoints when the source is definitely a PDF, and over full-text extraction endpoints when you only need the answer to a specific question rather than the entire document text.

## Known failure modes

- PDF URL is not publicly accessible or returns a 403/404 — no content to parse
- PDF is password-protected or encrypted — content cannot be extracted
- PDF is image-only/scanned without OCR text layer — question cannot be answered
- Question is unrelated to document content — may return empty or low-confidence answer
- Malformed or non-PDF URL provided — request rejected
- Large PDF documents may time out or return partial answers

## How this service works

Submits a public PDF URL and a natural-language question, then returns a text answer based on the document content.

## Output

A natural-language text answer derived from the content of the specified PDF document, directly responding to the submitted question.
