How it works

One API call. Every signal you need.

/01

Send the IP

Curl, fetch, or our SDK. Zero setup. The IP can come from your server, your edge, or your client. Wherever you have it.

/02

Get the verdict

Country, city, ASN, ISP, datacenter detection, VPN/Tor/proxy classification, abuse history, fraud score 0–100. Edge-cached.

/03

Act on it

Block, challenge, allow, or just log. We tell you what we know. What you do with it is your call.

Quickstart

No SDK.
No build step.
Just a curl.

  • Public endpoint, no auth, no signup
  • Edge-cached for 5 minutes
  • 100 calls per day, then sign up for 10,000

Where it's used

One IP call. Six places it pays for itself.

Drop a single fetch into your signup, login, checkout, or API gateway. Every signal you need to decide block / challenge / allow / log.

Signups

Block bad signups before they cost you anything.

Score the IP at registration. Disposable + datacenter + Tor signals catch 80% of fake accounts before they touch your DB.

"action": "block"
Logins

Challenge. Don't reject. VPN users.

Real customers use NordVPN. Real attackers use NordVPN. The fraud_score + abuse history tells them apart so you know when to step up auth instead of locking out.

"action": "challenge"
Checkout

Hold orders from server farms.

No legitimate human shops from a bare datacenter IP. Catch the BIN-test bots before they validate your refund processor at scale.

"action": "hold"
Comments / UGC

Stop spam at the network layer.

Known abusers, recently active scrapers, hijacked subnets. All flagged with confidence levels so you can tune how aggressive your filter wants to be.

"is_abuser": true
API rate limits

Throttle by reputation, not just rate.

A trusted residential ASN gets your full RPS. A flagged subnet gets soft-throttled before it can hammer your gateway. Same endpoint, smarter limits.

"shared_connection": true
Geo enrichment

Free, accurate, every visitor.

Country, region, city, lat/lon, timezone, ASN, ISP. The same dataset Cloudflare and Stripe pay for. Yours for free at every tier.

"city": "Mountain View"
