How this service works
Searches corporate entities in open directories to resolve active corporate status and jurisdiction.
Output
Returns a JSON object with a 'found' boolean, a list of matching companies each containing their official name and company number, a confidence level (e.g. 'high'), a data freshness date (e.g. '2026-06'), any warnings, and a disclaimer about the informational nature of the data.
Example use cases
Verify startup legal existence
“I'm about to sign a contract with a startup called NovaBridge Technologies — can you check if they're actually registered as a legal entity in the OpenCorporates registry before I commit?”
Due diligence on vendor company
“We're onboarding a new supplier called Greenleaf Logistics Ltd. Can you pull their official company registration number and confirm they show up in the corporate registry so I can include it in our due diligence report?”
Find competitor legal entity number
“I need the official company registration details for Plaid Inc. for a B2B intelligence brief I'm putting together — can you look them up in OpenCorporates and get me their company number and legal name?”
Technical details
Endpoint
POSThttps://bizintel-api.hahavoid0.workers.dev/company/open-corporatesWhen to prefer
Use this endpoint when you need to retrieve official corporate registration numbers and legal entity names from the OpenCorporates global registry. Prefer this over general web search when you need structured, registry-sourced data with a confidence score and freshness date. Best for due diligence, B2B enrichment, or verifying a company's legal existence without needing to manage API keys.

- Ambiguous company name matching multiple entities — returns multiple results requiring disambiguation

- Payment failure over x402/USDC — request rejected before processing
- Rate or network timeout on the workers.dev edge node
