Prefer the compact GET /amcas/data/summary?cycle=2026-27 endpoint. Omit cycle for the configured current cycle. Unsupported or duplicate/array cycles return 404; unavailable stored data returns retryable 503. Average n counts reporting dates, not applicants. Transcript values are aggregate voluntary reports, not representative of all applicants.
Check freshness and average.end before describing observations as current. Historical cycle summaries retain original dates. Official queue observations are not individual wait guarantees.
Public reading requires no account. User entry routes change records and are not data-discovery endpoints.
