Crustdata API / Identify a company from name, domain, ID, or profile URL

Match a company by name, website domain, profile URL, or Crustdata company ID. Returns one or more matches ranked by confidence score. This endpoint is useful for entity resolution before enrichment. The API returns a top-level array with one result per submitted identifier. Each match currently includes company_data.crustdata_company_id and company_data.basic_info. Exactly one identifier type must be provided per request. Default rate-limit is 30 requests per minute. Send an email to gtm@crustdata.co to discuss higher limits if needed for your use case.
