How this service works
IP risk check (beta) for logins and checkouts: is a public IPv4 address on the Spamhaus ZEN blocklist (spam, botnets, hijacked networks) or a Tor exit node? Includes the network owner. Returns a low, medium or high risk level.
Output
Returns a risk assessment for the given IPv4 address, likely including risk score, flags for VPN/proxy/Tor usage, abuse history, geolocation signals, and an overall risk verdict indicating whether the IP is safe or suspicious.
Example use cases
Block high-risk signups at registration
“Before letting this user create an account, check whether their IP address 198.51.100.77 shows any fraud or proxy signals that should block them.”
Flag suspicious checkout traffic
“A purchase just came in from IP 203.0.113.15 — can you screen that IP for risk to decide whether to hold the transaction for review?”
Audit login attempt from unusual IP
“We got a login from 192.0.2.88 that seems unusual. Can you do an IP risk check on it to see if it's a VPN, Tor exit node, or otherwise flagged?”
Technical details
Endpoint
GEThttps://api.payperscreen.com/screen-ip?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call IP reputation check without a subscription, especially in fraud prevention, user onboarding, or transaction monitoring flows where you only need to screen occasional or high-value IPs. It complements PayPerScreen's other screening tools (email trust, sanctions, crypto address) for a multi-signal risk picture.
Side effects
- Invalid or private IP address provided — endpoint expects a public IPv4 address
- Missing required 'ip' query parameter returns an error
- IPv6 addresses may not be supported (IPv4 only per schema)
- Unknown or unresolvable IP may return low-confidence results
- Beta status means output schema and reliability may change without notice
- Rate limits or payment failures may cause 402/429 errors
