How to choose

What to check before you pick

  1. Job to be done: search results, full page content, crawling a whole site, or long-running research.
  2. Output format: clean Markdown or structured data that fits in a model's context.
  3. Freshness and index: real-time fetching versus a pre-built index.
  4. Rate limits and latency for your agent's loop.
  5. Pricing unit: per search, per page or per credit. Check each vendor's pricing page.

This checklist is general advice. Check each vendor's docs and pricing page for current details.
