Common questions

Who is this API for?: Developers building apps for contractors — estimate tools, field service platforms, permit checkers. If you're a landscaper looking for leads, see our Quote Widget instead.
What's included in $29/mo?: Access to all endpoints, 10,000 API calls/month, email support, and 99.9% uptime SLA. Overage billed at $0.002/call.
Is permit lookup available everywhere?: Coverage varies by municipality. The API returns available data or a clear 'not in database' response — no silent failures.
Can I try before paying?: Join the waitlist and we'll send sandbox credentials. Paid plans include a 7-day refund if the API doesn't fit your stack.
