Common questions about plans, usage capacity, and billing.
No. Every plan uses the same core Signup Risk API analysis and produces the same type of explainable risk score and allow, review, or block decision. Paid plans primarily increase request capacity, throughput, automation, and operational capabilities.
Upgrading gives your application more monthly request capacity and, depending on the plan, access to higher throughput, bulk processing, webhooks, and additional operational capabilities. Choose the tier that matches the scale and workflow requirements of your application.
Yes. The Free plan includes the complete core signup-risk analysis so you can evaluate email, name, and domain risk checks and receive explainable allow, review, or block decisions before moving production traffic to a paid plan.
Annual plans are paid once per year and save up to 15% compared with paying the same plan monthly for twelve months. The plan's features and monthly usage capacity remain the same.
No. Request and explanation allowances continue to operate as monthly limits even when the subscription is billed annually. Annual billing changes how you pay, not how usage capacity is allocated.
Use Free to evaluate the API. Developer is designed for smaller production applications, Growth for increasing registration volume, Scale for high-volume automated workflows, and Business for large production workloads. You can choose Enterprise when your organization requires custom volume, throughput, integrations, security requirements, or support arrangements.
Enterprise is intended for organizations whose requirements do not fit the standard self-service plans, including custom request volume, throughput, integration, security, or support needs.
