Design notes for 17 Apify Actors built for AI-agent callers.

Per-Actor design notes. Each page covers what the Actor does, why I built it that way, what it deliberately doesn’t do, and how to call it. The Apify Store page for each Actor remains authoritative for current pricing and stats.

They’re on the Apify Store and callable via MCP, x402, or Skyfire agentic-payment rails.
