# RX_API_Call

## Objective
Create a very basic API using tools and languages of your choice. The API will have a single endpoint/method
with a single function.
### API Input
1. User Location - The API will receive a latitude and longitude value which describes the current location of a
user.
### API Output
1. The API will return a simple response packet with the name and address of the pharmacy chosen by the
application.
2. The distance between: the input latitude/longitude and the location of the pharmacy.
### Business Requirements
1. The API will receive a latitude/longitude, using the provided list in pharmacies.csv the API will calculate the
closest pharmacy to the input latitude/longitude.
2. The API will return the closest pharmacy (with name and address) in a consumable response packet. 
3. The API will include the distance (in miles) between the input latitude/longitude and the selected closest pharmacy
in the response packet.

Table Schema

```

	Zip TEXT,
	Latitude REAL not null,
	Longitude REAL not null
);
```

Call: https://rhays.us/Examples/RX_API_Call/RX.php?K=RLH1234&Latitude=39.1030&Longitude=-95.3222

This is a basic lookup system to find the closest pharmacy to a given Lat/Lon

My assumptions:
1. No clear request for distance, options are drive distance or straight line distance, I chose: straight line distance.
2. No request for trap errors, I added a few, validation, key check, request check, and a basic DB check.
3. Output was requested as a packet but not the type, so I just passed the requested data back as text and not JSON.
