VRP quickstart

Welcome to the VRP solver API! You can test our API in just one command:

curl https://api.solvice.io/v2/vrp/demo -H "Authorization: <<apiKey>>" |  \
curl https://api.solvice.io/v2/vrp/solve -H "Authorization: <<apiKey>>" \
     -X POST -H "Content-Type: application/json" -d @-

This will fetch a demo instance and solve it.
You can also solve your own instance by replacing the demo instance with your own instance.
Most of the time, you will want to solve your own instance.
In this case, you will need to create a VRP request payload and send it to the /v2/solve endpoint. You can find the
schema of the request in the Schemas section.

A VRP request will consist of resources (schema:resources) and
jobs (schema:jobs).
