How Superdata works

  1. Choose the matching API. Select Social URL to Email, Email Lookup, Email Validation, Profile, Profile Posts, Company, or Company Posts for the data your workflow needs.
  2. Provide a known record. Send an email address, a public profile or company URL, or another supported identifier, with your authenticated request.
  3. Use the response. Superdata returns structured data with request and credit metadata, ready for your application or automation.
  4. Track usage. Accepted executions appear in your account-level Usage dashboard, whether they came from REST or a connected MCP client.
