Frequently Asked Questions

Include your API key in the X-Api-Key header with every request. Your API key is available in the Enrichley dashboard after signing up for a paid plan. Keep your API key secure and never expose it in client-side code.
The default rate limit is 10 requests per second and 10 concurrent requests per connection. If you need higher throughput for bulk verification, contact our support team to discuss enterprise options.
Unlike other services that simply mark catch-all domains as 'risky' or 'unknown', Enrichley uses proprietary techniques to identify valid inboxes within catch-all domains. This recovers 20-30% more valid emails that competitors miss.
The API returns statuses including: 'valid' (deliverable), 'invalid' (undeliverable), 'risky' (catch-all or other risk factors), 'unknown' (unable to determine). Each response includes detailed flags like is_catchall, is_disposable, and is_role_based.
Each email verification consumes one credit. You can check your remaining credits using the /me endpoint. Credits roll over month-to-month and never expire as long as your subscription is active.
