Checklist

What to look for in an API-style option

Prefer an official API when the source offers one that fits. Otherwise look for a maintained scraper with a clear schema, exports and pricing.

  • An official or well-documented API when the source offers one
  • If not: a maintained Apify Actor with clear input/output schema
  • Export formats (JSON/CSV) and webhook/API hooks for automation
  • Transparent usage pricing and run logs
