> Tanod pdfpeek PDF Metadata is a paid API for AI agents from tanod.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

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 tanod-pdfpeek-pdf-metadata-87482f15 -d '<json body>'
```

Example prompt: Can you read the metadata from this PDF — https://example.com/report.pdf — and then update the author field to 'Jane Smith' and the keywords to 'annual report, finance, 2024'?

## When to prefer this

Use this endpoint when you need to programmatically read, update, or purge document metadata from a PDF — especially when you need to set author/creator/keywords fields for publishing workflows, audit what metadata a PDF contains before sharing, or sanitize PDFs by stripping all embedded Info and XMP metadata prior to distribution.

## Known failure modes

- PDF URL is inaccessible or returns non-PDF content
- PDF exceeds 20 MB (URL) or 10 MB decoded (base64)
- Malformed base64 input causes decode failure
- PDF is password-protected or encrypted, preventing metadata access
- URL scheme is not http/https

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns the PDF's document metadata fields (author, creator, subject, keywords, producer) after any read/write/strip operations. If metadata was modified or stripped, the response reflects the updated state of the PDF's Info and XMP metadata.
