A semantic retrieval API that feeds context to your system

It is not a search box but a retrieval API for programs: find pages similar in meaning, filter by date and other conditions, and pass the fetched text downstream as context. Useful for knowledge-base Q and A, material collection and automation. The cost is thinking clearly about what you want: loose filters return pages that look related but are useless, so keep a set of human-reviewed samples to judge results.

What it does

  • Semantic retrieval that matches meaning, not keywords
  • Filters for publish date, category and more
  • Returns page text for downstream models
  • Built for automation and batch calls
  • API docs and examples make integration direct

Who it is for

  • A self-built Q and A system needs a stable external context source
  • Batch-finding similar pages for data cleanup
  • Keyword search keeps missing differently worded but related results
  • Running comparison tests on retrieval quality

How to get started

  1. Prepare twenty real queries as a small sample; do not start on production traffic
  2. Keep sources alongside fetched text for traceability
  3. Tighten filters based on false hits, then scale call volume gradually
