## 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-pdf-repair-bcbb98b5 -d '<json body>'
```

Example prompt: This PDF I'm working with seems corrupted and won't open properly — can you repair it and also linearize it for fast web viewing? Here's the URL: https://example.com/broken-report.pdf

## When to prefer this

Choose this endpoint when you need to repair, reconstruct, or sanitize a broken or malformed PDF file and optionally prepare it for fast web delivery via linearization. Ideal for pipelines that receive PDFs from untrusted sources and need active content stripped, or for recovering documents that fail to render in standard viewers. Pay-per-call with no signup required makes it suitable for low-volume or agent-driven workflows.

## Known failure modes

- PDF URL is inaccessible, private, or points to a non-PDF resource
- PDF exceeds 20 MB (URL) or 10 MB decoded (base64) size limit
- URL points to an internal or IP-literal host (refused for security)
- PDF is so severely corrupted it cannot be reconstructed
- Neither url nor pdf_base64 provided
- base64 input is malformed or not a valid PDF

## 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 a JSON object containing the repaired PDF as base64-encoded data, along with metadata including file name, page count, byte sizes before and after repair, whether reconstruction occurred, warnings list, whether active content was removed, and whether linearization was applied.
