Data Source Atlas
data_source_atlasGiven a real question about a local market or a specific property, returns a source-first RESEARCH PLAN: which public record actually settles the question, how to reach it directly (county parcel GIS, Census CBP/ACS/permits, BLS series, state registries, licences, inspections), what the answer will be worth, and what the public record cannot answer at all. Use it before researching a local market, to find the administrative record that settles the question.
Example invocations:
"Where would I actually find what 1420 Grand Ave in Saint Paul last sold for?"
"I want to know if Wichita has room for another dog daycare — what should I pull?"
"How do I find out who really owns this building and what else they own?"
"What public data would tell me if this neighborhood is actually growing?"
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| place | Yes | The specific geography — 'Hennepin County, MN', 'Wichita, KS', 'the 78704 ZIP'. State matters more than people expect: it decides whether sale prices exist at all. | |
| question | Yes | The real question, in plain words — e.g. 'is there room for another coffee shop in Bend' or 'what did the building at 412 Main last sell for'. Not a dataset name; the point of this tool is to work out which records answer a question you can only phrase in English. | |
| already_tried | No | What you already looked at and what it failed to answer, if anything. Keeps the plan from re-recommending a dead end. |
