Frequently Asked Questions
How does the free tier work?
Sign up, get an API key, and make 100 calls per month across all endpoints. No credit card required. No expiration. If you need more calls, upgrade anytime.
What happens if I exceed my monthly limit?
Your API calls will return a 429 status code. We never charge overage fees. You can upgrade your plan at any time from the dashboard and your new limits apply immediately.
How fast are the API responses?
Business Lookup averages 300-400ms. Website Audit takes 2-5 seconds depending on the target site. Review Response and SMS Generate return in under 500ms. All endpoints include latency_ms in the response.

No. One API key works across all five endpoints. You can create multiple keys on paid plans for different projects or environments.
Is there an SDK?
We provide official SDKs for Python, Node.js, and PHP. You can also use any HTTP client — the API is standard REST with JSON request/response bodies.
