# Welcome to BETA

> Cited company intelligence — API + MCP server for builders.

BETA is a developer API and MCP server for **cited company intelligence**. It powers AI agents and the systems that depend on accurate, source-linked company data.

673 curated companies. \~7,200 SEC-filer entities tracked. News-corroborated weekly. Every response carries provenance — what BETA used to answer, and a deliberate refusal when sources don't back the claim.

## Who this is for

AI-agent builders, AI-first SaaS, and any system where being wrong about company facts has a cost. Drop-in for [Claude Desktop](https://claude.ai/download), agent frameworks, and your own backend code.

## Who it isn't for

Sales enrichment workflows (use [Apollo](https://apollo.io) or [Clearbit](https://clearbit.com)), data-lake feeds (use [ZoomInfo](https://zoominfo.com) or [PitchBook](https://pitchbook.com)), and prosumer use cases. BETA's depth is in **synthesis + citation discipline**, not in flat data dumps.
