Bot signals — AI crawler & agent
Google-Agent IP addresses
Google-hosted user-directed agents only; excludes common crawlers and generic/customer-controlled fetcher feeds.
01 — Verification
How IPAPI.GR verifies Google-Agent.
Only from what Google-Agent 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 Google-Agent address sets risk.is_ai. 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 Google-Agent but doesn't match is unverified.

About Google-Agent.
Where does Google-Agent publish its IP addresses?
Google-Agent publishes its addresses at https://developers.google.com/static/crawling/ipranges/user-triggered-agents.json. IPAPI.GR reads that publication directly, not a third-party copy.
How often is the Google-Agent list refreshed?
IPAPI.GR re-fetches it every hour. If a refresh fails, the previous entries expire after at most 24 hours instead of being trusted forever.
Which risk flag does Google-Agent set?
A matching address sets risk.is_ai in the lookup response. The risk flags are returned for Pro API keys.
