How you pay

Pay per result. Failures are free.

Every tool uses Apify's pay-per-event billing: you are charged a fixed, published price for each result it delivers, and nothing for inputs it could not process.

A price per resultPer website, per document, per page, per frame. Fractions of a cent, published on each tool's page. No subscription, no seats.
Failures cost $0Unreachable sites, broken downloads and unreadable files come back as rows with an error message, so you can see what happened, and they are not charged.
You set the ceilingSet a maximum cost per run and the tool stops cleanly when it is reached. A long list can never cost more than you decided.

Use from AI assistants (MCP)

Ask your assistant. It calls the tool.

The Kanto Labs MCP server plugs every tool into Claude, Cursor, VS Code Copilot, Windsurf and any other MCP client. Ask “What is stripe.com built with?” or “Convert this PDF to Markdown and summarize section 3” and the assistant runs the right tool on your own Apify account.

  • Every call has a spending cap (default $1.00), so an assistant cannot run up a bill by accident
  • Each result states what the call cost
  • Runs on your machine and talks only to the Apify API
