    - **HTTP Basic Auth**: Use your token as the username with empty password

    - **Bearer Token**: Include token in Authorization header

    - **Query Parameter**: Pass token as `?token=YOUR_TOKEN`

    ## IPinfo API Tiers


    IPinfo offers three main API tiers with different feature sets:


    ### IPinfo Lite

    Lightweight IP geolocation with essential information including ASN details, country, and continent data. Perfect for basic geolocation needs with fast response times. Unlimited requests on paid plans.

    - Endpoints: `/lite/me`, `/lite/{ip}`, `/lite/{ip}/{field}`

    - Base URL: `https://api.ipinfo.io/`

    - [Documentation](https://ipinfo.io/developers/lite-api)


    ### IPinfo Core

    Comprehensive IP information with detailed geolocation data (city, region, coordinates, postal code, timezone), ASN information, and classification boolean flags (anycast, hosting, mobile, satellite).

    - Endpoints: `/lookup/me`, `/lookup/{ip}`, `/lookup/{ip}/{field}`

    - Base URL: `https://api.ipinfo.io/`

    - [Documentation](https://ipinfo.io/developers/core-api)


    ### IPinfo Plus

    All Core features plus mobile/carrier detection, anonymity analysis (VPN, proxy, Tor, relay detection), service identification, and extended geographic metadata. Ideal for security, fraud prevention, and advanced analytics.

    - Endpoints: `/plus/me`, `/plus/{ip}`, `/plus/{ip}/{field}`

    - Base URL: `https://api.ipinfo.io/`

    - [Documentation](https://ipinfo.io/developers/plus-api)


    ## Specialized Detection APIs


    ### Residential Proxy Detection

    Detect residential, mobile, and datacenter proxy IPs with activity insights, last seen dates, and proxy service identification.

    - Endpoints: `/{ip}/resproxy`

    - [Documentation](https://ipinfo.io/developers/residential-proxy-api)


    ### Privacy Detection Standard

    Detect VPNs, proxies, Tor exit nodes, relays, and hosting providers associated with an IP address. Returns core privacy signals including service provider identification.

    - Endpoints: `/{ip}/privacy`

    - [Documentation](https://ipinfo.io/developers/privacy-standard-api)


    ### Privacy Detection Extended

    Advanced anonymous IP detection with detailed methodologies, confidence metrics, and metadata for VPNs, proxies, Tor, hosting providers, and relays.

    - Endpoints: `/{ip}/privacy_extended`

    - [Documentation](https://ipinfo.io/developers/privacy-extended-api)


    ## Legacy API Products


    For backwards compatibility, legacy endpoints remain available:

    - [IP to Geolocation API](https://ipinfo.io/products/ip-geolocation-api) - Use Core or Plus instead

    - [IP to Privacy Detection API](https://ipinfo.io/products/proxy-vpn-detection-api) - Use Plus instead

    - [ASN API](https://ipinfo.io/products/asn-api) - `/AS{asn}` endpoint

    - [IP to Company API](https://ipinfo.io/products/ip-company-api) - `/{ip}/company` endpoint

    - [IP to Abuse Contact API](https://ipinfo.io/products/ip-abuse-contact-api) - `/{ip}/abuse` endpoint

    - [IP WHOIS API](https://ipinfo.io/products/whois-api) - `/whois/*` endpoints


    ## Special Endpoints


    - **Token Info**: `/me` - View request limits and API access for your token

    - **Batch Requests**: `/batch` - Enrich multiple IPs in a single request

    - **IP Summarization**: `/tools/summarize-ips` - Analyze up to 500,000 IPs

    - **IP Mapping**: `/tools/map` - Visualize up to 500,000 IPs on an interactive map

    - **Single Field**: `/{ip}/{field}` - Get specific field values as plaintext


    ## Rate Limits
