How this service works
Check names, crypto wallets, emails and IP addresses against official sanctions lists and risk signals. 2 cents a check, no contract, no account. Built so your software, or your AI agent, can run it on every customer and every payment.
Output
Returns a trust assessment for the submitted email address, likely including risk signals such as whether the email is from a known disposable or temporary domain, spam reputation, fraud history, and an overall trust or risk score to help decide whether to approve or reject an interaction with that email.
Example use cases
Pre-onboarding email fraud check
“Before I approve this new user signup, can you screen the email address they registered with — registrant@quickmail.biz — and tell me if it looks risky or disposable?”
Payment recipient email screening
“I'm about to send a large transfer to client@freeemailprovider.net — can you do a trust check on that email first to make sure it's not flagged for fraud?”
Fraud triage for support tickets
“We've got a suspicious support ticket from user99@yopmail.com claiming a refund — can you run an email trust check on that address to see if it looks like a bad actor?”
Technical details
Endpoint
GEThttps://api.payperscreen.com/screen-email?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.02) per-email risk signal during user onboarding, payment flows, or fraud triage — especially when you want to complement crypto/sanctions screening with email-layer trust signals. Ideal for platforms that need lightweight email reputation checks without building their own email intelligence pipeline. Works well alongside PayPerScreen's IP risk check and sanctions screening for multi-signal fraud prevention.
Side effects
- Missing or malformed email address returns a 400 or validation error
- Invalid email format rejected before screening
- Unknown or unresolvable domain may reduce confidence in result
- Payment not completed results in 402 Payment Required response
- Rate limiting or quota exceeded returns 429 error
