Zestimate Tracker (a/k/a update-zestimate)

==========================================

Python based AWS Lambda function for checking the Zillow Zestimate of a 

given property value.

When triggered, this function pulls a CSV from a configured S3 location 

and the current Zillow Zestimate (including rental estimates) for a 

specified property. If the date of the last update to the Zestimate is 

newer than the last date in the file, a message is published to an 

SNS topic with the new value and the full Zestimate response is 

appended to the CSV.

Zestimates API documentation: https://bridgedataoutput.com/docs/explorer/zestimates#listZestimates

Expected Environment Variables

------------------------------

+ zaddress - Address to track

+ zwsid - Bridge Interactive API Server Token (for server-to-server communication)

+ bucket_name - S3 bucket name to store Zestimate history

+ bucket_key - S3 object name to store Zestimate history

+ sns_topic_arn - SNS topic to publish to when new updates available

Deployment

----------

Continuous Deployment is done via the GitHub Actions workflow. Alternatively, 

the included [Makefile](./Makefile) will build a ZIP file which can be 

deployed to AWS Lambda. This ZIP file will include all dependencies 

(including Pandas, and therefore rather large).
