Frequently Asked Questions
Everything you need to know about VerifNow.
VerifNow is a real-time API that validates emails, phone numbers and custom form fields before they reach your database. It helps you reduce bounces, block fake accounts, and keep your data clean.
We run multi-layer checks: syntax verification, DNS and MX record lookups, typo detection (e.g. gmail.con → gmail.com), disposable and role-based address detection, domain reputation signals, and a quality score from 0 to 100. The depth of checks depends on your plan.
No. VerifNow is a REST API — just send an HTTPS request with your API key and get a JSON response in milliseconds. Official SDKs are available for Java and Spring Boot (io.verifnow:verifnow-spring-boot-starter on Maven Central) and for Node.js and TypeScript (@verifnow/sdk on npm), plus ready-to-paste cURL examples.
Yes. The Free plan gives you 250 validations per month running the full STANDARD check set — DNS and MX lookups, typo detection, disposable and role-based detection, and a 0–100 quality score. Same checks as the Starter plan, no credit card, no time limit.
Your API keeps working — there is no service interruption. Extra requests beyond your plan's quota are billed per unit at the end of the billing period. The higher your plan, the lower the overage price.
Typical response time is under 50 ms (p50), measured on our production endpoints. VerifNow runs with monitoring, alerting and zero-downtime deployments. We do not publish a contractual uptime guarantee at this stage — get in touch if you need an SLA.
Absolutely. All traffic is encrypted over HTTPS, API keys are stored securely with rotation support, and validation inputs are never persisted beyond the processing window. We collect the minimum data necessary to operate the service.
Yes. The client dashboard lets you track requests, errors, and latency in real time. You can filter by endpoint, monitor trends after deployments, and manage your API keys — all from one place.
