Xtract search API
Xtract search API is a search API that returns pages with usefulness scores and prices for AI agents.
Xtract search API provides search results that include a usefulness score and a price for each page before an agent fetches the full content. It flags pages that have been replaced by later events, helping agents avoid outdated information. Users send a GET request with a query and an optional task description to sharpen the scoring process. The service uses Keenable for search results and OpenAI models to generate scores. Feedback can be sent via a POST request with fetched and cited URLs to adjust future results.
