VPNAPI.io

API3FreeAirnode v0.1.4
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.

Served at https://airnode-vpnapi.fly.dev/. Each operation is reached the way the provider documents it, under https://airnode-vpnapi.fly.dev/api, and answers with the provider's own response and the attestation in headers, so a client built against the provider works unchanged. The same operations are also served as one JSON envelope on POST /, which the HTTP interface covers. Every request below can be sent from this page, and what comes back is verified right here in the browser.
ANY /api/…
The provider's own requests, one per operation, forwarded as they are. The provider's response comes back untouched, with the attestation in the X-Airnode headers.
Whether one IP address is a VPN, proxy, Tor node or private relay, with its location and network alongside.
Verify the response
Paste a response to verify it originates from the current Airnode: the JSON a POST / answers with, or a passthrough response with its headers, as curl --include prints it.
