LinqAlpha

LinqAlpha is a domain-specialized multi-agent AI platform for institutional investment research, serving hedge funds, asset managers and investment banks. It runs retrieval-augmented, agentic analysis across SEC filings, earnings-call transcripts, IR materials, news and macroeconomic data covering 57,600+ companies in 120+ countries and 30+ languages, returning answers with inline citations that resolve to the exact source chunks. The LinqAlpha API exposes that engine over a REST surface at api.linqalpha.com — streaming analytics and chat over Server-Sent Events, document search, natural-language-to-SQL, scheduled research briefings, an RMS/Vault ingestion path for a firm's own internal documents, and a source-grounding judge that scores how well each claim in an answer is backed by the sources it cited. LinqAlpha also publishes a first-party remote MCP server exposing 22 financial-data tools to AI assistants.

LinqAlpha publishes 10 APIs on the APIs.io network, including Briefing API, Connectors API, Data API, and 7 more. Tagged areas include Company, Financial Services, Investment Research, Artificial Intelligence, and Agents.

LinqAlpha’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, signup flow, authentication, and 21 more developer resources.
