Use Signup Risk Score API to detect burner emails, suspicious seller details, risky infrastructure, and low-quality onboarding patterns before sellers create listings or contact buyers.
Seller onboarding is one of the most important checkpoints in a marketplace. Risky sellers can create fake listings, abuse promotions, contact buyers, evade bans, or damage marketplace trust before your team has enough context to react.
Disposable emails and low-quality account details make it easier for bad actors to create repeat seller profiles.
Risky sellers can damage buyer confidence before moderation or support teams detect the issue.
Without a consistent risk score, teams must manually inspect seller applications with limited context.
Send seller signup context during onboarding and receive a clear recommendation your marketplace can use immediately.
Pass the seller email, optional name, optional IP address, and marketplace industry context during onboarding.
The API evaluates disposable email evidence, domain infrastructure, provider classification, identity details, name match, and optional IP reputation.
Allow low-risk sellers, review uncertain sellers, or block very high-risk attempts before listings, messaging, or payouts are enabled.
Identify confirmed or likely burner domains often used for fake seller accounts and ban evasion.
Compare supplied seller 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 seller email uses a free provider, business domain, disposable provider, or unknown provider.
Check DNS, MX, SPF, and DMARC posture to understand whether a seller domain appears established or risky.
Reuse recent results to reduce repeated analysis and recognize recurring signup patterns across seller onboarding.
Let low-risk sellers continue onboarding when the checks show no major concerns.
Send uncertain sellers to manual review, document checks, payout holds, or reduced-permission onboarding.
Stop very high-risk seller attempts before listings, buyer contact, or marketplace access are enabled.
Use the recommendation directly for a simple onboarding gate, or inspect the check breakdown to route sellers into custom review workflows.
Catch suspicious seller signups before they create listings or interact with buyers.
Add a risk checkpoint before high-impact marketplace actions are enabled.
Use risk details to focus manual review on the seller applications that need attention most.
Scale seller onboarding without treating every new seller like a manual investigation.
Use Signup Risk Score API to evaluate seller signups in real time and route each attempt with an allow, review, or block recommendation.
