> Tanod pdfpeek PDF OCR is a paid API for AI agents from tanod.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

## 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-ocr-402d013c -d '<json body>'
```

Example prompt: Can you OCR pages 1 through 3 of this scanned PDF — https://example.com/report.pdf — at 200 DPI in English and give me the extracted text?

## When to prefer this

Use this endpoint when you need to extract text from a scanned or image-based PDF that has no existing text layer, or when you want to add a searchable layer to specific pages of a document. Ideal for up to 10 pages at a time, especially when Tesseract's English OCR coverage is sufficient. Prefer this over generic document parsers when you need pay-per-call, serverless OCR without managing infrastructure.

## Known failure modes

- PDF URL unreachable or exceeds 20 MB — request fails with error
- Base64 payload exceeds 10 MB decoded — rejected
- Requested more than 10 pages — rejected
- Language code not installed in Tesseract (only 'eng' available) — error
- DPI out of range 100-300 — validation error
- Open-ended page ranges (e.g. '3-') not allowed — validation error
- More than 5 pages at the low price tier may incur higher cost or be rejected

## 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 searchable text layer added to the specified PDF pages, along with the recognized text extracted from those pages, enabling copy-paste and full-text search on previously image-only PDF content.
