Site24x7- API flag
risk.is_crawler
A user agent alone never sets a flag. Anyone can claim to be Site24x7; the flag follows the address the request comes from.
02 · In the response
What a match looks like.
A lookup of a Site24x7 address sets risk.is_crawler. The flags come with geolocation and network data in the same response, for API keys on every paid plan.
The response says which kind of bot an address belongs to, not which operator. A request that claims to be Site24x7 while risk.is_crawler is false should not be trusted as Site24x7.

03 · Control
Allow or block Site24x7.
Your options
- robots.txt works only for crawlers that choose to follow it. Check the operator’s documentation for the token it reads.
- Firewall, WAF or CDN. Many offer bot rules you can allow or deny by category. Use them to enforce what robots.txt only asks for.
- In your app. Look up the client address and allow or deny on
risk.is_crawler, alongside the user agent. - Never on the user agent alone. Blocking the name stops only honest clients; allowing it lets anyone in who borrows it.
