Government — entry 087 of 90
OpenRegistry
OpenRegistry aggregates live company-registry data from 30 national and sub-national jurisdictions — UK Companies House, France Sirene+RNE, Germany's Handelsregister, Spain's BORME, South Korea's OPENDART, and more — exposing search, profile, officers, shareholders, and filings lookups. It ships as both a Streamable-HTTP MCP server (OAuth 2.1 with dynamic client registration, no pre-shared API keys) for AI agents and a Bearer-authenticated REST API for direct integration, returning unmodified upstream government data with source URLs preserved. Beneficial-ownership registers restricted under EU law (e.g. post-CJEU C-37/20 jurisdictions) return HTTP 501 with a pointer to the statutory portal rather than being proxied. The free tier covers most jurisdictions at 30 req/min; paid Pro ($29/mo) and Max ($99/mo) tiers raise throughput and cross-border fan-out, with Cayman Islands company data gated to paid tiers only.
