Rate limits & caching

• Responses are cached publicly for 5 minutes with stale-while-revalidate of 15 minutes.
• No per-key rate limit at this stage. Hammer it lightly and we'll add one before it becomes a problem.
• Endpoints respond with permissive CORS so you can call them directly from a browser app.

Attribution

When you display data sourced from this API, please include a visible attribution link. Suggested wording:

Data caveats

The risk index is a composite signal, not a clinical case-rate forecast — see methodology for the formula and limitations. For public-health decisions, consult the underlying authoritative sources directly: WHO, CDC, PAHO, ProMED-mail.
