Quirks & gotchas

Salesforce SPA — JS-rendered, not scrapeable; TLS chain also fails strict verification. Underlying machine-readable catalog is HealthData.gov (already polled) — treat this page as human-facing frontend only.

This catalog describes where public health data lives and how to access it. It is not medical advice, and it does not host or redistribute the data itself — always read each source's own documentation, licence, and suppression rules before using it. Access details drift; entries carry the date we last verified them. Sources marked RESTRICTED are listed for reference only — they require an application or data-use agreement and we never automate access to them.
