AletaIndex Financial Narrative Intelligence API is a financial narrative intelligence tool for AI agents, developed by AletaIndex and open-sourced on GitHub. Its core idea is to give AI agents a "financial narrative brain," rather than just receiving raw news feeds or simple sentiment scores.
Purpose
The tool is used to track how financial stories evolve in real time across thousands of news sources, cluster related articles into structured narratives, measure sentiment momentum, and map narrative risk to portfolios. It targets the U.S. stock market, covering 109 stocks across all major industries. Agents can use it to understand what the market is currently talking about, how intense the discussion is, and whether the narrative is shifting.
