Web search API and crawler built for AI agents
Run natural-language or keyword queries against a large independent web index with filters for domain, date and category.
Return cleaned page text and AI-extracted highlights so agents receive the most relevant excerpts instead of entire pages.
Choose fast, balanced or deep search modes so an assistant can answer instantly or run longer grounded research.
Extract structured outputs such as company details, people and other entities for list building and data pipelines.
Real-time web search and retrieval APIs built for AI agents
Returns ranked, LLM-ready results with highlights and optional full content, designed to hold steady latency even under very high query concurrency.
Automatically splits one complex question into parallel sub-queries and merges the results, giving agents broader coverage from a single call.
Dedicated embedding families for text and for vision-language retrieval, letting teams embed pages, images, video, and documents into a shared vector space.
Turns any URL into clean Markdown with intent-focused highlights and a classified page type, so downstream models receive structured, noise-free input.
