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.

Quickstart

Install, authenticate, and make your first API call in under 60 seconds.

Endpoints

Five live endpoints: validate, enrich, timeline, corroborate, people.

Citation Contract

The provenance grammar — and what BETA refuses to assert.

​
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, agent frameworks, and your own backend code.

​
Who it isn’t for

Sales enrichment workflows (use Apollo or Clearbit), data-lake feeds (use ZoomInfo or PitchBook), and prosumer use cases. BETA’s depth is in synthesis + citation discipline, not in flat data dumps.
