Use Signup Risk Score API to detect burner emails, suspicious account details, risky infrastructure, and low-quality signup patterns before users create repeat accounts or abuse free-tier access.
SaaS trials reduce friction for legitimate buyers, but they can also attract repeat abusers, disposable inboxes, suspicious account details, and risky infrastructure. Signup risk scoring gives your product a checkpoint before fake users consume product resources.
Users create multiple accounts to keep accessing trial or free-tier features without converting.
Disposable domains and temporary inboxes make it easy to create low-commitment or abusive accounts.
Datacenter, VPN, proxy, Tor, or other high-risk network context can indicate attempts to hide signup behavior.
Send the signup context your app already collects and get back a risk decision your product can use immediately.
Pass the email, optional name, optional IP address, and SaaS industry context during account creation.
The API evaluates disposable email evidence, domain infrastructure, provider classification, identity details, name match, and optional IP reputation.
Allow trusted users, review uncertain signups, or block very high-risk attempts before they consume product resources.
Identify confirmed or likely burner domains commonly used for fake accounts and repeat trials.
Compare supplied name details with the email local part and flag mismatches or low-quality account details.
Classify contextual infrastructure risk such as datacenter, VPN, proxy, and Tor usage without returning raw IPs.
Understand whether the email appears to use a free provider, business domain, disposable provider, or unknown provider.
Check DNS, MX, SPF, and DMARC posture while separating non-existent domains from temporary lookup failures.
Reuse recent risk results to reduce repeated analysis and recognize recurring signup patterns.
Let low-risk users create accounts normally when the checks show no major concerns.
Challenge uncertain signups with email confirmation, extra verification, manual review, or usage limits.
Stop very high-risk attempts before they create accounts, consume trial resources, or enter your product database.
Use the recommendation directly for a low-maintenance integration, or inspect the check breakdown for custom trial access rules.
Reduce repeat account creation from users trying to avoid trial limits.
Keep fake users and low-quality signups from distorting trial metrics.
Stop suspicious accounts before they create moderation, billing, abuse, or support issues.
Apply extra friction only when risk details justify it instead of challenging every user.
Use Signup Risk Score API to evaluate SaaS signups in real time and route each attempt with an allow, review, or block recommendation.
