How do I construct a REST query for ArcGIS to obtain the nearest SSA field office?

Question

I am trying to use one of the US Social Security Administration's APIs, which is an ArcGIS REST service API. It looks extremely powerful, but overwhelming with how complex it is. I am hoping for an example for a simple query.

I am using Python but might just construct the API using the Requests module rather than learning a new library, so I don't need Python specific info.

Here is the endpoint: http://services6.arcgis.com/zFiipv75rloRP5N4/ArcGIS/rest/services/Office_Points/FeatureServer/1

My goal is to be able to tell an SSA recipient where the nearest 2-3 offices are, based on their address, which can be geocoded to latitude/longitude if necessary (it would be great to use the ArcGIS API for that too. Otherwise, I'm within the free tier of Google's geocoding API). I successfully queried to obtain the office matching a zip code, but it looks like I can provide a Geometry of type Point (lat/lng?) and find offices within a set distance. I'm just not understanding how to provide the information to the API nor where to find this in the documentation.

replace your lat and long values here &geometry=-96.915919%2C32.693022&geometryType=esriGeometryPoint&inSR=4326
