ETAs as a service. Provides single-pickup and multi-dropoff routes. Takes into account time and traffic.

# ETAs Service

Add accurate estimated time of arrival to apps for delivery tracking, routing directions and much more.

Current limitations:
• Only supports "Driving" (not walking, cycling)
• Does not optimize route

## Usage

The ETA service depends on the Google Maps API. Ensure you set the "google.maps.apikey" config value to your API key.

```shell
micro config set google.maps.apikey YOUR_API_KEY
```

Once set, run the service using `micro run github.com/micro/services/etas`.

```shell
$ micro call etas ETAs.Calculate $(cat example-req.json)
