Validate an address, work out a subnet's range, or check whether an address falls inside it.

Validate and classify IPv4/IPv6 addresses, expand CIDR ranges and test membership.

Response

The result carries your remaining balance alongside it, so you can track spend without a second call.

Cost

1 credit per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.

A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.

Parameters

Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
