-
Query parameter authentication: Unlike many modern APIs that use Bearer tokens in headers, Hunter requires the API key as a query parameter (
api_key=YOUR_KEY). Ensure your API client is configured to pass credentials via query string. - Monthly quotas: Hunter enforces strict monthly limits on searches and verifications based on your subscription plan. Track your usage carefully and implement quota monitoring to avoid service disruptions mid-month.
- Rate limiting: In addition to monthly quotas, Hunter may enforce rate limits on requests per second. If you’re processing large batches, implement delays between requests to avoid 429 (Too Many Requests) errors.
- Email pattern confidence scores: When Hunter returns email addresses from domain searches, they include confidence scores. Not all results are verified emails—some are patterns Hunter has inferred. Always check the confidence score and consider verifying important addresses before use.
- Free plan restrictions: The free plan has limited searches per month and may not include access to all API endpoints or advanced features. Upgrade to a paid plan if you need higher limits or additional functionality.
