If the date of the last update to the Zestimate is \nnewer than the last date in the file, a message is published to an \nSNS topic with the new value and the full Zestimate response is \nappended to the CSV.\n\nZestimates API documentation: https://bridgedataoutput.com/docs/explorer/zestimates#listZestimates\n\nExpected Environment Variables\n------------------------------\n\n+ zaddress - Address to track\n+ zwsid - Bridge Interactive API Server Token (for server-to-server communication)\n+ bucket_name - S3 bucket name to store Zestimate history\n+ bucket_key - S3 object name to store Zestimate history\n+ sns_topic_arn - SNS topic to publish to when new updates available\n\nDeployment\n----------\n\nContinuous Deployment is done via the GitHub Actions workflow. Alternatively, \nthe included [Makefile](./Makefile) will build a ZIP file which can be \ndeployed to AWS Lambda. This ZIP file will include all dependencies \n(including Pandas, and therefore rather large).\n\nContributing\n============\n\nThis project is governed by a [Code of Conduct](./CODE_OF_CONDUCT.md).
