Use Signup Risk API to evaluate registrations before granting free trials, AI credits, API usage, storage, compute, or other costly account benefits. Get an explainable allow, review, or block recommendation from one server-side API.

Free trials and free tiers reduce friction for legitimate buyers, but every new account can also consume credits, inference, API capacity, storage, compute, support time, or other product resources. Repeated or low-quality registrations can create meaningful cost long before a payment is ever attempted.
Users may create multiple accounts to continue receiving free access after trial limits are reached. Signup Risk API helps your application evaluate each new registration before benefits are granted.
Disposable and temporary inboxes can make repeated account creation inexpensive and difficult to manage.
Datacenter, VPN, proxy, or Tor infrastructure may justify additional review when combined with other signup evidence.
Add Signup Risk API to the registration flow before your application issues trial credits, enables premium features, or grants other costly account benefits.
Send the email address and optionally include the user’s name and signup IP for additional context.
Signup Risk API evaluates disposable-email usage, domain infrastructure, provider type, role addresses, typo domains, synthetic identity patterns, name alignment, and optional IP reputation.
Use the allow, review, or block recommendation to grant normal access, introduce additional verification or limits, or stop very-high-risk attempts before valuable trial resources are consumed.
Detect confirmed, likely, and suspicious disposable-email usage that may make repeated account creation inexpensive.
When a name is supplied, evaluate how well it aligns with the email address and whether the supplied identity appears plausible.
When IP context is available, evaluate network characteristics such as datacenter, VPN, proxy, or Tor usage as one part of the broader signup decision. Raw signup IPs are not returned in the API response.
Classify common consumer, business, education, government, and unknown providers without treating provider type alone as proof of abuse.
Evaluate domain existence and mail-related DNS infrastructure (such as MX, SPF, DMARC, and reserved or special-use domains) while distinguishing authoritative findings from temporary lookup failures.
Detect known provider-domain typos and guarded near-match domains that may represent mistyped or suspicious registration addresses.
Grant normal trial or free-tier access when the available evidence shows few meaningful risk factors.
Add friction selectively with email confirmation, lower initial limits, additional verification, or manual review when the evidence is uncertain.
Stop very-high-risk attempts before granting trial credits, free-tier resources, or other valuable account benefits.
Use the recommendation directly for a simple integration, or inspect the check-level evidence to apply custom trial-access rules.
The goal is not to eliminate every questionable registration. It is to prevent expensive account benefits from being granted blindly when the signup evidence justifies additional friction. A free signup is only free to the user. For the product, it may consume inference, API capacity, storage, compute, support time, onboarding resources, or promotional value. Signup Risk API helps you make the access decision before those costs are incurred.
Evaluate registrations before issuing AI credits, API credits, compute, storage, or other resources with a real marginal cost.
Keep lower-risk registrations moving while reserving additional verification, reduced limits, or review for signups with stronger risk factors.
Reduce the number of low-quality registrations entering activation, retention, and conversion reporting so product metrics better reflect the users you actually want to measure.
Signup Risk API recommends allow, review, or block; your application decides what each action means for your product.
Use Signup Risk API alongside Clerk, Auth0, Supabase, Firebase, Cognito, or a custom authentication system. Call it from your backend before granting costly trial or free-tier benefits.
Add Signup Risk API before trial activation and start making explainable allow, review, or block decisions before granting credits, compute, storage, or other valuable account benefits.
