Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 pdf-to-text-extractor-upload-4e5be6b8 -d '<json body>'
```

Example prompt: Can you extract all the text from this PDF file I have — just upload the raw bytes and give me back the content as plain text?

## When to prefer this

Use this endpoint when you have a PDF file available as raw bytes, a multipart upload, or base64-encoded content and need to extract its text layer quickly and cheaply. Prefer this over the URL-based PDF endpoint when the PDF is already in memory or on disk rather than hosted at a URL. For scanned PDFs without a text layer, use the OCR-capable document parsing endpoint instead.

## Known failure modes

- HTTP 400 if file does not start with %PDF (not a real PDF)
- HTTP 400 if file exceeds 20 MB limit
- HTTP 400 if PDF has no text layer (e.g. scanned image-only PDF without OCR)
- HTTP 400 with hint message for malformed or corrupt PDF files
- Network timeout on very large documents near the size limit

## How this service works

PDF to text from uploaded bytes. POST the raw PDF as the body (content-type application/pdf); multipart 'file' or JSON {"base64"} also work. Real PDF only (starts with %PDF), max 20 MB, with a text layer. Optional ?format=text|markdown. Bad files get HTTP 400 with a hint and are not charged. Sample: https://agents.crowdspark.me/samples/sample.pdf

## Output

Returns the extracted text content of the PDF as plain text or markdown (depending on the optional ?format= parameter). Covers all text layers present in the document. Bad or non-text PDFs return HTTP 400 with a descriptive hint and are not billed.
