Apify tools: PDF to Markdown, OCR, Website to Markdown crawler, SEO audit, Tech Stack

Working examples for my pay-per-use tools on the Apify Store. Each one is an API: send URLs, get JSON back. You only pay for what you process, and there's no subscription.

Quick start (curl)

Get an API token from Apify Console → Integrations, then:

curl -X POST "https://api.apify.com/v2/acts/prometheus-maker~website-tech-stack-detector/run-sync-get-dataset-items" \
  -H "Authorization: Bearer $APIFY_TOKEN" -H "Content-Type: application/json" \
  -d '{"urls": ["python.org"]}'

The same endpoint works for the other tools: replace the tool name and the input.

Use them from Claude, Cursor or any MCP client

Every tool is also an MCP server, hosted by Apify (streamable HTTP). Add one to your client with your Apify token:

{
  "mcpServers": {
    "pdf-to-markdown": {
      "url": "https://mcp.apify.com/?tools=prometheus-maker/pdf-document-to-markdown",
      "headers": { "Authorization": "Bearer YOUR_APIFY_TOKEN" }
    }
  }
}

Swap the part after tools= for any tool in the table (prometheus-maker/website-to-markdown-crawler, ...), or list several separated by commas. The same entries are in the official MCP Registry under io.github.prometheus-maker/* (files in mcp/). You pay per use, as with the API.

Python

pip install apify-client
export APIFY_TOKEN=...
python python/pdf_to_markdown.py      # PDF → Markdown + RAG chunks
python python/image_to_text_ocr.py    # image → text
python python/tech_stack.py           # domains → technologies
python python/website_to_markdown.py  # website → Markdown pages + chunks
python python/seo_audit.py            # website → SEO scores, issues, broken links

The scripts are in python/. They use apify-client 3.x.
