This is the common background service implementation for ZeroTier One, the VPN-like OS-level network virtualization service.
It provides a ready-made core I/O loop and a local HTTP-based JSON control bus for controlling the service. This control bus HTTP server can also serve the files in ui/ if this folder's contents are installed in the ZeroTier home folder. The ui/ implements a React-based HTML5 user interface which is then wrappered for various platforms via MacGap, Windows .NET WebControl, etc. It can also be used locally from scripts or via *curl*.
Values POSTed to the JSON API are *extremely* type sensitive. Things *must* be of the indicated type, otherwise they will be ignored or will generate an error. Anything quoted is a string so booleans and integers must lack quotes. Booleans must be *true* or *false* and nothing else. Integers cannot contain decimal points or they are floats (and vice versa). If something seems to be getting ignored or set to a strange value, or if you receive errors, check the type of all JSON fields you are submitting against the types listed below. Unrecognized fields in JSON objects are also ignored.
API requests must be authenticated via an authentication token. ZeroTier One saves this token in the *authtoken.secret* file in its working directory. This token may be supplied via the *auth* URL parameter (e.g. '?auth=...') or via the *X-ZT1-Auth* HTTP request header. Static UI pages are the only thing the server will allow without authentication.
A *jsonp* URL argument may be supplied to request JSONP encapsulation. A JSONP response is sent as a script with its JSON response payload wrapped in a call to the function name supplied as the argument to *jsonp*.
To join a network, POST to it. Since networks have no mandatory writable parameters, POST data is optional and may be omitted. Example: POST to /network/8056c2e21c000001 to join the public "Earth" network. To leave a network, DELETE it e.g. DELETE /network/8056c2e21c000001.

Path objects describe direct physical paths to peer. If no path objects are listed, peer is only reachable via indirect relay fallback. Path object format is:
