# Tanod Docs PDF Repair

> Tanod Docs PDF Repair is a paid API for AI agents from docs.tanod.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-13).

Repairs and sanitizes a corrupt or malformed PDF, optionally linearizing it for fast web view, and returns the fixed file as base64 or a download URL.

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-docs-pdf-repair-6c2b1a09 -d '<json body>'
```

Example prompt: This PDF is corrupted and won't open properly — can you repair it and send back the fixed version as a download link rather than inline data?

## When to prefer this

Use this endpoint when you need to fix a corrupt, malformed, or potentially unsafe PDF before further processing (OCR, conversion, storage, or display). It is also the right choice when you need to linearize a PDF for fast browser streaming, or sanitize a PDF by removing active/scripted content. Prefer it over generic conversion endpoints when the input is already a PDF and the goal is healing or hardening it rather than format conversion.

## Known failure modes

- PDF URL is private, internal, or IP-literal — returns error refusing the URL
- PDF exceeds 20 MB via URL or 10 MB via base64 — returns size limit error
- Neither url nor pdf_base64 provided — returns validation error
- PDF is so severely corrupted it cannot be reconstructed — may return error or reconstructed:false
- Network fetch of the provided URL fails or times out — returns fetch error

## How this service works

Documents: DOCX template fill, Office to PDF, any file to Markdown, PDF to Word, OCR, PDF pipeline.

## Output

Returns a JSON object with the repaired PDF file (name, byte count, page count, content type, and data as base64 or a 24-hour download URL), a boolean indicating whether repair was performed, a reconstructed flag, a list of warnings, counts of bytes before and after, and a report of any active content removed.
