mcaapi 0.1.1

A Python wrapper for the Maricopa County Assessor API.

API Token

Use of this library requires obtaining an API Key from The Maricopa County Assessor's Office. This can be done by visiting https://preview.mcassessor.maricopa.gov/contact/ and filling out the form.

Change the "Subject" Field to "API Token/Question", provide your name, number, and a brief note. Then click "Send Message". MCA's web developer will send you an email shortly after with the API Key.

Once you have the token, all you need to do is import mcaapi. The first time this is run, it will prompt you for the API token. Simply paste the token into the prompt, and it will store it in a file located in the source directory of the library.

Quick Examples

To query an address, name, parcel number (apn), city, street, subdivision, etc, use the Search.all() method as follows:

import mcaapi
resp0 = mcaapi.Search.all('301 W Jefferson, Phoenix') #The Assessor Office's Address
resp1 = mcaapi.Search.all('Phoenix')
resp2 = mcaapi.Search.all('11219038A') #The Assessor Office's own APN

This will return a JSON object with limited information to your variable containing a maximum number of items (I believe up to 100). Unfortunately, the limit and offset parameters are currently not working as per the Maricopa County Assessor API docs, which can be found here [PDF]. I have coded in the logic to support this when it is working, and will do my best to keep it updated as things change.

You can get more details for each APN, by using the Parcel.details() method as follows:

import mcaapi
resp3 = mcaapi.Parcel.details('11219038A')

This will provide a substantial number of details about the parcel, its location, ownership, zoning, physical features, and more.

For educational purposes, I have engineered a toy dataset of approximately ten-thousand unique parcels which can be found in the mcaapi/datasets directory.

Classes

The structure of the wrapper follows the same structure as the API documentation which can be downloaded here: https://preview.mcassessor.maricopa.gov/file/home/MC-Assessor-2021-API-Documentation.pdf

Not all API calls are supported at this time, per the documentation. I have still written methods for all of these, but they will only be functional after they fix the API.

Here is the documentation for each Class, which defines the inputs and outputs of each method, as well as examples.
