# Chicago Cityscape API
The Chicago Cityscape API returns data about an address in Illinois or a Property Index Number (PIN) in Cook County, Illinois. Returned data can including information about elected officials, TIF districts, nearby CTA & Metra stations, and potential financial incentives for that address or PIN. The most information is returned for Chicago addresses.
Using the API requires a `key` which is available to certain members and can be found on your [My Account](http://chicagocityscape.com/account.php) page. API usage is available to
## Three API services (endpoints)
### 1. Property Report API
[Property Report API documentation](API%20-%20Property%20Report.md)
The Property Report API returns the same information that you get in an [Property Report](http://chicagocityscape.com/address.php).

#### Sample API calls
Get a response for an address in Chicago. If the API call doesn't have coordinates, the API will automatically geocode the address. Provide coordinates using `lat` and `lng` parameters (this will also marginally speed up the response).
````
https://www.chicagocityscape.com/api/index.php?address=333 N Michigan Ave&city=Chicago&state=IL&key=your_key_here
````
Get a response for a PIN in Cook County. If the PIN is found but doesn't have a record in the Cook County Parcel 2019 GIS layer, then the PIN is geocoded.

### 2. Parcels API
[Parcels API documentation](API%20-%20Parcels.md).
This API returns a GeoJSON dataset of Cook County parcels within a radius (in feet) of a WGS84 geographic coordinate, inside a bounding box passed to the API as a GeoJSON polygon, or inside or within a radius (in feet) of one of our thousands of Place Snapshots (using the `slug` parameter).

### 3. Places API

Download boundaries for wards, community areas, neighborhoods, Chicago Public Schools attendance areas, and other kinds of boundaries in GeoJSON format.
## Troubleshooting
- If you are using cURL to access the API and you are receiving results but unexpected results, try sending the parameters as a JSON payload, or "-d" properties, rather then encoding them in the URL.
