The context API for AI agents.

Entity search, indexed extract, and disruption watch for AI agents — structured context with honest labels, never a silent fallback.

Try API for free

Search the crawled web index — category routing is automatic, filters (time, domains, full text) optional.

Ground agents in owned sources

Over MCP, agents call entity search and crawl search_web — passages from SeaWeb’s own index with the page URL and crawl date, never a rented SERP silently filling gaps.

Models shouldn’t parse HTML

Hand over a URL and get the readable document back — title, clean text, passages. Indexed pages return with their crawl date. Free browser accounts stay index-only; Growth and API keys may live-fetch on a miss.

Structured context, or an honest no

Every MCP response is typed. When search_web can’t stand behind an answer it says uncertain or unavailable — a label your agent can act on, not a silent guess.

{
  "coverage": "covered",
  "results": [
    {
      "title": "Ferry Building Marketplace",
      "url": "https://…/ferry-building",
      "passage": "Open daily; ferry and
         BART connections on the Embarcadero.",
      "fetched_at": "2026-07-31",
      "match_quality": "strong"
    }
  ]
}
