SEER API (Surveillance, Epidemiology, and End Results Program)
NCI SEER Program web service (REST, free API key). Exposes registry tooling — SEER site recode / ICCC / AYA algorithms, hematopoietic & lymphoid disease database, SEER*Rx drugs, staging, NAACCR documentation — but no population statistics; US incidence, mortality and survival statistics are published through SEER*Explorer (connector seer-explorer). With a key this connector validates access and records the available recode algorithm versions used to interpret SEER site groupings.
