Fundamental Research Labs

Fundamental Research Labs (formerly Altera) is an applied AI research company building autonomous, collaborative AI agents, founded by researchers from MIT EECS, the Stanford NLP Group, Google X, and Citadel and backed by Andreessen Horowitz and Prosus. Its flagship product, Shortcut, is an AI analyst for Excel that turns natural-language prompts into full spreadsheet models — LBOs, DCFs, three-statement models, waterfalls — and ships a web app, desktop app, Excel and Google Sheets plugins, a ShortcutXL terminal agent (CLI), and a Platform API. The Shortcut Platform API lets teams submit spreadsheet-automation jobs, poll status, download generated workbooks, upload context files, list agent skills, and export organization usage data programmatically using API-key bearer authentication.

Fundamental Research Labs publishes 3 APIs on the APIs.io network: Authentication API, Spreadsheets API, and Usage API. Tagged areas include Company, Artificial Intelligence, Spreadsheets, Excel, and Financial Modeling.

The Fundamental Research Labs catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Fundamental Research Labs’ developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, engineering blog, support, and 26 more developer resources.
