  title: Aligned News REST Bundles Signals API
  description: 'Read-only REST API for the Aligned News AI intelligence platform.


    The API exposes Aligned News'' Stories, Signals, Reports, Bundles, the

    section-grouped news feed, and full-text search. All endpoints require an

    API key passed as `Authorization: Bearer alnw_...`. API keys are issued to

    Pro and Enterprise subscribers from their account page at

    https://alignednews.com/account.


    Note: this specification was reconstructed by inspecting the Aligned News

    web application bundle and the published MCP server reference implementation

    (https://alignednews.com/mcp-server.ts). The provider does not currently

    publish a machine-readable API description.
