⚡ Reliability
Best When
A compliance team, bank, fintech, or due diligence provider wanting AI agents to access corporate registry data, verify company existence, research beneficial ownership, and monitor company status across 200+ global jurisdictions through OpenCorporates' open company data platform.
Avoid When
DATA FRESHNESS VARIES BY JURISDICTION: OpenCorporates data currency depends on source registry update frequency; automated real-time registry assumption creates stale_data for jurisdictions with slow update cycles; automated must understand jurisdiction-specific data freshness before relying on time-sensitive company data. BENEFICIAL OWNERSHIP DATA IS INCOMPLETE: Beneficial ownership data is available for some jurisdictions (UK PSC, EU UBO registers); automated global UBO coverage assumption creates no_ubo_data for jurisdictions without public UBO registers; automated must supplement with manual due diligence for non-public-register jurisdictions. COMPANY NAME MATCHING IS APPROXIMATE: Corporate entity names vary significantly across jurisdictions; automated exact-match company search assumption creates false_negative for name variations; automated must implement fuzzy matching and reconciliation for reliable company identification. RATE LIMITS APPLY TO FREE API: OpenCorporates free API has tight rate limits; automated free-tier high-volume assumption creates rate_limit_exceeded; automated must upgrade to commercial API for production-scale company verification.
Use Cases
- • Performing KYB company verification across 200+ jurisdictions for global fintech onboarding automation agents
- • Researching beneficial ownership and corporate structure for AML due diligence automation agents
- • Monitoring company status changes (dissolution, strike-off) for risk management automation agents
- • Reconciling company names to official registry records for procurement and supply chain due diligence automation agents
Not For
- • Financial statements and credit scores (OpenCorporates is registry data, not financials or credit ratings)
- • Real-time company news and events (OpenCorporates is registry filings, not news monitoring)
- • Individual person background checks (OpenCorporates focuses on legal entities, not natural person KYC)

Agent Metadata
Known Gotchas
- ⚠ JURISDICTION CODE IS REQUIRED: OpenCorporates uses jurisdiction codes (us_de, gb, au_nsw) for company lookup; automated jurisdiction-free search assumption creates ambiguous_jurisdiction for companies with same name in multiple registries; automated must specify jurisdiction code for precise company lookup
- ⚠ COMPANY NUMBER FORMAT VARIES: Company registration numbers have different formats by jurisdiction (UK: 8-digit, US: state-specific); automated uniform company number assumption creates format_error for non-standard registry numbers; automated must handle jurisdiction-specific company number formats
- ⚠ RECONCILIATION IS THE RIGHT TOOL FOR MATCHING: OpenCorporates has dedicated reconciliation service for mapping company names to registry records; automated simple-search-for-matching assumption creates lower_match_rate than reconciliation service; automated should use reconciliation API for name-to-entity matching
- ⚠ DISSOLVED COMPANIES ARE IN DATABASE: OpenCorporates includes dissolved and inactive companies; automated active-only assumption creates false_positive from dissolved company matches; automated must filter by company status (active) for due diligence that requires active entity verification
- ⚠ FREE TIER IS 500/DAY: OpenCorporates free API allows only 500 requests/day; automated high-volume free-tier assumption creates rate_limit_exceeded; automated must upgrade to commercial plan for production-scale company verification workflows
