About
GetJsonip is an IP address lookup API that returns a client's IPv4 or IPv6 address in JSON format. It supports direct browser requests, CORS requests from web applications, and JSONP callbacks for client-side use.
The service also exposes IPv4-only and IPv6-only endpoints, plus an HTTP-only endpoint without TLS. The page describes the API as free and unlimited, but it does not state a separate quota, billing limit, or time window for the free offering.
- JSON IP address response
- IPv4 and IPv6 support

- HTTP-only no-TLS endpoint
Free Tier Value
This free tier has no stated usage cap and is available without signup friction, so it behaves like a perpetual public API rather than a limited trial. Because there is no paid plan on the page to anchor against, the practical monthly value is modest but real — roughly $2/month for an always-available, unlimited lookup service with browser-friendly access.
