# Query Parameters for Probes

You can filter on most of the fields of the probe, directly, in the same vein as you would with measurements. The list of all filter query parameters is here.

A few interesting filters are those that do location based filtering.

There is a latitude and a longitude filter that can also be combined with a __gte and __lte suffix. You could form a bounding box where you want to look for probes:

GET /api/v2/probes/?latitude__lte=40.0&latitude__gte=20.0&longitude__lte=70&longitude__gte=60

It's also possible to combine the latitude, longitude and radius into one single radius= query parameter that searches probes within the defined circle. It has the following syntax:

GET /api/v2/probes/?radius=51.5,0.12:10
