              Usage

              Example commands for calling this service from scripts and tools.

              Most simple way to get your IP address is to call: 

              
curl ip.syrc.io    # dual-stack (either IPv4 or IPv6)
curl -4 ip.syrc.io # IPv4 only
curl ipv4.syrc.io  # IPv4 only   
curl -6 ip.syrc.io # IPv6 only
curl ipv6.syrc.io  # IPv6 only

              Output format: Plain-text (raw)

              Returns your IP address as a single line of plain text. 

              
curl https://ip.syrc.io/raw    # dual-stack (either IPv4 or IPv6)
curl -4 https://ip.syrc.io/raw # IPv4 only   
curl https://ipv4.syrc.io/raw  # IPv4 only   
curl -6 https://ip.syrc.io/raw # IPv6 only
curl https://ipv6.syrc.io/raw  # IPv6 only

              Output format: JSON

              Returns full request metadata as JSON, identical across all hosts. 

              
curl https://ip.syrc.io/json   # dual-stack (either IPv4 or IPv6)
curl https://ipv4.syrc.io/json # IPv4 only
curl https://ipv6.syrc.io/json # IPv6 only

              Extracting only the IP address from JSON using jq: 

              
curl -s https://ip.syrc.io/json | jq -r '.requesting_ip'   # dual-stack (either IPv4 or IPv6)
curl -s https://ipv4.syrc.io/json | jq -r '.requesting_ip' # IPv4 only
curl -s https://ipv6.syrc.io/json | jq -r '.requesting_ip' # IPv6 only

              Output format: JSONP (requesting IP only)

              Returns only the requesting IP as JSON. Optional: ?callback=functionName for JSONP (e.g. for cross-origin script tags). 

              
curl "https://ip.syrc.io/jsonp"                      # JSON: {"ip":"1.2.3.4"}
curl "https://ip.syrc.io/jsonp?callback=myCallback"  # JSONP: myCallback({"ip":"1.2.3.4"});
curl "https://ipv4.syrc.io/jsonp?callback=cb"        # IPv4 only
curl "https://ipv6.syrc.io/jsonp?callback=cb"        # IPv6 only

              Output format: Via Accept header

              Set the format via Accept header, available on all 3 endpoints (ip.syrc.io, ipv4.syrc.io, ipv6.syrc.io) 

              
curl -H "Accept: text/plain" https://ip.syrc.io        # prefer raw (dual-stack)
curl -H "Accept: application/json" https://ip.syrc.io  # prefer JSON (dual-stack)
curl -H "Accept: text/html" https://ip.syrc.io         # prefer HTML (dual-stack)
