VPN detection is common; identifying residential proxies — the ones that look like ordinary home connections and are sold specifically to evade detection — is harder and more valuable. Having it as a separate tool means an agent can ask the precise question. ipinfo_quota is the well-mannered companion: an agent can check what it has left before working through a list, and the free-versus-detailed split is stated in each tool's own description.
IPinfo's endpoint, which listed six tools to our probe as ipinfo 3.1.1. Most take a list of IPs with paging, so a batch is one call rather than many.
- ipinfo_lookup — geolocation, network and metadata for one or many IPs, using the free lite API by default
- ipinfo_geolocate and ipinfo_asn — location, and autonomous-system network ownership
- ipinfo_check_privacy — whether an IP is behind a VPN, proxy, relay, Tor, anycast, hosting or mobile network
- ipinfo_check_residential_proxy — whether it is a known residential proxy
- ipinfo_quota — daily and monthly request counts and what is left
A free token, sent on each request. The detailed=true option is a paid feature; without it the tools use the free lite data.
