ZipCodeGPT

• Get Zipcode Profile — Get demographic and housing profile data for one or more US zipcodes, aggregated by census study year: population, households, median income, home values, rent, race/ethnicity breakdown, housing stock age, and more.
• Find Nearby Zipcodes — Find zipcodes adjacent to or within a radius of a center zipcode, ordered nearest first. Use this to build a zipcode list for an area before fetching profiles or generating insights.
• List Available Metrics — List census metrics available for trend analysis, grouped by category. Call without arguments to see category names, then call again with a category to get its metric column names (usable with get_metric_trend).
• Get Metric Trend — Get the multi-year time series of a census metric for a set of zipcodes, optionally compared against a second set of zipcodes.
• Generate Ai Insights — Generate an AI-written analysis report of census trends for one or more zipcodes (comparison analysis when multiple zipcodes are given). Costs 1 credit per zipcode from the user's ZipcodeGPT account; repeat requests for the same zipcodes are free (cached). May take 30-60 seconds.
• Ask Census Question — Ask the ZipcodeGPT census AI a free-form question about specific zipcodes, e.g. "Which of these areas is most family friendly and why?". Starting a new conversation costs 1 credit per zipcode; follow-up messages in the same conversation are free (pass the returned session_id).
