VPNAPI.io
by
API3FreeAirnode v0.1.0
VPNAPI.io answers, for one IP address, whether it belongs to a VPN, a proxy, a Tor node or a private relay, and returns the address's approximate location and the network it sits in alongside. This Airnode wraps the single lookup the API offers, so a consumer receives the verdict with a signature saying this Airnode obtained it from VPNAPI.io at this time. Detection is a judgement rather than a measurement, and VPNAPI.io revises it as its own data changes, so what a signature binds is what the provider said about the address at that instant.
Every response carries an EIP-191 signature from the Airnode that served it, so the data can be attributed back to its source rather than trusted on reputation.
