Company Enrichment API

Yes. A website domain is the most common input: send domain=example.com and the API returns that company's profile, including name, industry, size, founding year, LinkedIn page, tickers, and workforce analytics. Full URLs, www prefixes, and even whole email addresses are reduced to the bare domain for you, so you can pass values straight from a CRM.

Each match returns firmographics (industry, company type, size, founding year), domains and social profiles, office locations with the headquarters flagged, LinkedIn page details, stock tickers, and workforce analytics: employee count with monthly history, hiring and attrition, growth and turnover rates, and distributions by seniority, job function, tenure, and education.

The Company Enrichment API supports 6 matching methods: domain (e.g., google.com), company name with optional industry context, LinkedIn company page ID, social media profile URL, stock ticker symbol, and direct Legion ID lookup. The API automatically selects the best matching strategy based on the parameters you provide.

Every match includes a confidence level of high, moderate, or low. Confidence reflects how certain we are that we found the right company based on the parameters matched and the quality of the match.

If no match is found, the API returns HTTP 404. Try providing additional identifying information like industry alongside company name for better results.

The Company Enrichment API has a default rate limit of 100 requests per minute per API key. Higher limits are available for enterprise customers. For bulk enrichment, consider our data licensing option.

Authentication is handled via API keys provided when you set up your account. Include your API key in the API-Key request header.
