AI search and retrieval platform for modern apps and commerce
Deliver keyword, semantic, and hybrid results from a single index, with natural-language query understanding built in.
Create, test, and deploy AI agents, and generate grounded conversational answers via retrieval-augmented generation over your own content.
Use behavioral signals to surface related products and tailor results to each visitor's journey.
Curate category pages, pin or boost items, and track performance in dashboards without engineering support.

The search API that gives AI agents real-time web context
Low-latency search endpoints (Lite, Auto, Deep) return ranked pages, highlights and structured fields from an independent index covering a large share of the public web.
Retrieve full page text or token-efficient highlights with configurable crawl policies, so models get only the most relevant excerpts rather than whole documents.
Run asynchronous agent runs that navigate, reason and return structured outputs with grounded citations across 70M+ companies and other verticals.
Schedule recurring queries over news, people, companies and financials, and receive updates through webhooks when something changes.
