Bot signals — Internet scanner
Microsoft Internet-Wide Scanning is an internet scanning project in the IPAPI.GR scanner catalogue. Addresses it publishes or verifiably identifies as its own set risk.is_scanner.
01 — Verification
Only from what Microsoft Internet-Wide Scanning 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.
risk.is_scanner
02 — In the response
A lookup of a Microsoft Internet-Wide Scanning address sets risk.is_scanner. 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 Microsoft Internet-Wide Scanning but doesn't match is unverified.

03 — Questions
Yes. Microsoft Internet-Wide Scanning publishes a list at https://internetscans.microsoft.com/, which IPAPI.GR imports directly.
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.
A matching address sets risk.is_scanner in the lookup response. The risk flags are returned for Pro API keys.
