Frequently Asked Questions
What authentication does the API use?
+
The API uses Bearer token authentication. You'll get an API key from your dashboard that you include in the Authorization header of every request. Keys can be rotated at any time from the dashboard.
Is there a rate limit?
+
Yes. Free plans are limited to 10 requests per minute. Paid plans get 100-1,000 requests per minute depending on your tier. Batch endpoints have separate, higher limits. Rate limit headers are included in every response.
Do you have SDKs or client libraries?
+
The API is a simple REST/JSON interface that works with any HTTP client in any language. We provide code examples for Python, Node.js, Ruby, and cURL. No SDK installation required.
How does pricing work for API usage?
+
API usage is billed using the same credit system as the dashboard. 1 enrichment = 1 credit. Email verification = 1 credit. The free plan includes 30 credits per month. Paid plans start at $29/month for 500 credits.
Can I test the API for free?
+
Yes. Sign up and you'll immediately get 30 free credits. No credit card required. Use the API with your test key to enrich real contacts and validate the data quality before committing to a paid plan.
What response formats do you support?
+
The API returns JSON exclusively. All endpoints accept JSON request bodies and return structured JSON responses with consistent field names, confidence scores, and status codes.
