Tools

Each tool does one job, returns structured JSON with explicit reason codes and documents what it does not check.

Prices are the main per-result event on the Apify Store. Some tools add small events (a per-run start fee, per finding or per extra row); each Store page lists the full price, and error rows are never charged.

How it works

You run the tools where you already work: the Apify Store, your own code, n8n or an MCP client.

  • Pay per use

    Every paid tool charges per result: per email, per name, per page checked. There is no subscription and no minimum on Apify, and error rows are free on every tool. Prices are listed on each Store page.

  • Works with AI agents

    Call any tool through the Apify API or Apify MCP. The Agent Trust MCP server bundles PII redaction, email checks, sanctions screening and OSV lookups (7 of its 12 tools are free), and the Company Jobs Feed has its own MCP server on npm.

  • Your data stays yours

    Free tools run on your machine. Paid runs execute in your own Apify account under your storage settings. We don’t sell inputs or results or use them to train AI models. Data handling details
