Enrich any UK registered company with a single API call. Returns company profile, registered address, SIC codes, risk flags (insolvency, charges, liquidation), accounts due dates, confirmation statement status, active officers with nationality, and recent filings with plain-English descriptions. Optionally include persons with significant control (PSCs).
Official UK Companies House REST API — not scraped, not third-party. Always accurate and GDPR-safe.
POST /api/enrich — full enrichment by company number, supports include_pscs: true
GET /api/search?q=NAME&limit=5 — search companies by name, up to 20 results
GET /api/health — service health and credentials status
Due diligence, KYC, sales intelligence, legal research, compliance tooling, AI agent pipelines
The POST /api/enrich endpoint returns comprehensive company profiles, including registered address, SIC codes, risk flags, account statuses, active officers, and recent filings. The GET /api/search endpoint provides basic company details like company number, name, status, type, incorporation date, and registered address. The GET /api/health endpoint returns the API's operational status and available endpoints.
Key fields in the POST /api/enrich response include company_number, company_name, company_status, registered_address, SIC codes, risk flags, accounts, confirmation statement, and active_officers. For the GET /api/search response, key fields include company_number, company_name, company_status, company_type, incorporated_on, and address_snippet.
The response data is structured in JSON format. For the POST /api/enrich endpoint, data is organized into nested objects, such as registered_address and active_officers, allowing easy access to detailed information. The GET /api/search response includes an array of results, each containing essential company details, making it straightforward to parse multiple entries.
The POST /api/enrich endpoint provides detailed company profiles, including risk indicators and officer information. The GET /api/search endpoint allows users to find companies by name, returning basic details for up to 20 companies. The GET /api/health endpoint offers information on the API's operational status and available endpoints.
Users can customize requests to the POST /api/enrich endpoint by including the optional parameter include_pscs: true to retrieve information about persons with significant control (PSCs). For the GET /api/search endpoint, users can specify the query parameter 'q' to search for companies by name and limit the number of results returned.
The data is sourced directly from the official Companies House API of the UK, ensuring accuracy and compliance with GDPR. This eliminates the need for data scraping or third-party sources, providing reliable and up-to-date information about registered companies.
Typical use cases include due diligence, KYC (Know Your Customer) processes, sales intelligence, legal research, compliance tools, and AI agent workflows. The detailed company profiles and risk indicators support informed decision-making in various business contexts.
If the GET /api/search endpoint returns no results, users should verify the search query for accuracy or try broader terms. For the POST /api/enrich endpoint, if a company number is invalid or not found, the response will indicate this, allowing users to adjust their requests accordingly.
