### Integration Playbook: Lead Enrichment API Flow When a user submits a corporate email on your landing page, query Hunter's API in the background to verify its deliverability and enrich your CRM database profile: ```python # Verify email deliverability using Hunter API import requests def verify_lead_email(email): url = f"https://api.hunter.io/v2/email-verifier?email={email}&api_key={HUNTER_API_KEY}" response = requests.get(url).json() data = response.get("data", {}) if data.get("result") == "deliverable": return True return False ``` Block users who sign up with temporary or disposable emails to protect your outbound server's reputation score.
