TL;DR · WeSearch summary

OpenRegistry offers a free API alternative to OpenCorporates, providing significantly higher call limits for accessing UK, EU, and EEA company registries. While OpenCorporates limits free users to 200 calls per month, OpenRegistry allows 20 anonymous requests per minute across 16 jurisdictions. The service delivers real-time data from government sources with transparent audit trails and supports commercial use without licensing restrictions.
