The ASN WHOIS API provides detailed information about Autonomous System Numbers (ASNs), including the AS number, name, organization details, country, domain, allocation status, and associated IPv4 and IPv6 routes. It also returns upstream and downstream providers, peers, administrative and technical contacts, abuse contacts, and raw WHOIS data, all available in JSON or XML format.
Authorization
You can make authorized requests to our API by passing API key
as a query parameter. To get your API key, login to our billing
dashboard and get your API key! If your API key has been
compromised, you can change it by clicking on reset button in
billing dashboard.
