Keenable is a web search API for AI products that need the live web: AI labs, inference platforms and agent builders. It crawls, indexes and ranks the web in its own stack, over 100B+ documents updated in real time. What you get: latency under 250ms p95 in US East, and two agent tools, one to search the web and one to fetch a page as clean markdown. Both are available through a REST API, an MCP server and a CLI on a single key. Two tiers. Agent Builder Tier is pay as you go at $4 per 1,000 requests, cloud only, no commitment. Frontier Tier gives labs and inference platforms dedicated capacity from $1 per 1,000 requests at 100 RPS and above, with cloud or on-premises deployment. Quality is public: the NEEDLE benchmark reruns daily and compares search providers against an oracle ranking. Time Machine, in early access, adds point-in-time search across past versions of the web.
