Responses are cached for 24 hours (Cache-Control: public, max-age=86400, stale-while-revalidate=604800). If you need the whole dataset, please pull /bulk/all-districts.json once rather than looping over the 33,559 per-ZIP endpoints.

ZIP-code-to-district assignment is a geographic approximation: ZIP codes and school district boundaries do not align exactly, and a single ZIP code can be split across more than one district. Each record names the district covering the largest share of the ZIP code. Verify enrollment eligibility with the district itself.
