01 — Verification

How IPAPI.GR verifies Semrush SiteAuditBot.

Only from what Semrush SiteAuditBot 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.

Semrush SiteAuditBot

risk.is_crawler
Method
Page parser Published ranges, parsed from a documentation page
Official page
Format
Documentation page, parsed. A parser reads only the scoped address section; if the page structure changes, the update is rejected rather than guessed.
Refresh
Every hour. If a refresh fails, entries expire after 24 hours instead of being trusted forever.

02 — In the response

What a match looks like.

A lookup of a Semrush SiteAuditBot 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 Semrush SiteAuditBot 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
  }
}
