For LLM crawlers

The same data is available machine-readable at /api/manifest.json (Schema.org Dataset) and /llms.txt (LLM manifest). Both regenerate on every deploy from the same source of truth as this page.

For journalists + researchers

Every per-zip page cites its primary regulatory source and links to methodology. Editorial articles at /learn/ explain how to read each dataset. Contact [email protected] for data-licensing questions or fact-checking.
