Check an IP

Is this IP really Ahrefs crawlers?

Checks the address against what Ahrefs crawlers publishes, the same evidence behind risk.is_crawler.

01 — Verification

How IPAPI.GR verifies Ahrefs crawlers.

Only from what Ahrefs crawlers publishes about itself. No third-party blocklists, no behavioural guesses. Live address counts change with every publication, so check the official file for the current list.

02 — In the response

What a match looks like.

A lookup of a Ahrefs crawlers address sets risk.is_crawler. The flags come with geolocation and network data in the same response, for Pro API keys.

The response says which kind of bot an address belongs to, not which operator. Pair it with the user agent: a request that claims to be Ahrefs crawlers but doesn't match is unverified.

GET /api/lookup/{ip}?key=PRO_KEY
{
  // … location and network fields …
  "risk": {
    "is_ai": false,
    "is_crawler": true,
    "is_scanner": false
  }
}
