  title: AlphaSense Agent API
  description: >-
    GraphQL surface for embedding AlphaSense market intelligence into customer
    AI agents. Wraps GenSearch (auto / fast / thinkLonger / deepResearch modes),
    Workflow Agents, and the Document Search API behind an OAuth 2.0 +
    API-key-protected /gql endpoint. Returns markdown-formatted answers with
    inline citations into the AlphaSense corpus (filings, broker research,
    Tegus expert call transcripts, news, internal Enterprise Intelligence
    documents). Documented at
    https://developer.alpha-sense.com/agent-api/quickstart.
