Registry Lookup
Free, open API for 521M+ company records worldwide
Search and explore over 521 million legal entities across 309 jurisdictions in 200+ countries. Free company registration data, registry numbers, addresses, legal forms, and status information. 10x more free API calls than OpenCorporates and similar data providers.
Hey Product Hunt 👋
Company registry data is weirdly hard to get. Every country runs its own register, in its own format, behind its own paywall — and the one well-known aggregator gives you 500 free API calls a month, then asks for thousands of dollars a year for anything past that.
We thought the foundational layer, which companies exist, where, with what registry number and status, should just be open. So we built Registry Lookup.
It's a free API over 521M+ legal entities across 309 jurisdictions and 244 countries. You get 5,000 calls a month, no credit card — roughly 10x the free quota of OpenCorporates, and the same volume they charge $15,000/year for. Search by name, look up by registry number, browse by jurisdiction, autocomplete. JSON in, JSON out.
The part we're most excited about: there's an MCP server, so you can wire it straight into Claude, ChatGPT, or any agent and just ask: "find all active companies named Tesla in the US," "what's Companies House number 01026167," "how many entities are registered in Germany." Four clicks to connect in the Claude app, one line in Claude Code.
The data is powered by Veridion's global company database; we partnered with them to make the core legal-entity layer available for free. If you ever need to go deeper (firmographics, ownership chains, ESG, supply chain mapping), there's an enterprise path, but the registry layer remains free for everyone.
Grab a key, point your code or your AI assistant at it, and tell us what breaks. We're in the comments all day and genuinely want the feedback. 🙏
