Versioning

Each release is stamped with dataset_version (the build date) and generated_at; monthly snapshots under /reports/ are frozen forever. Cite a version, and the citation stays checkable: “GLP-1 Price Compare Dataset v2026-08-31”.

Integrity checks

Before a release ships, the build fails on any of: a 12-month rate higher than the same provider’s monthly rate flagged as cheapest; flat-dose = yes alongside multiple dose prices; membership $0 while the page mentions a fee; a source older than 60 days feeding a headline statistic; a price with no source URL; annual ÷ 12 disagreeing with the stated monthly equivalent; 28-day billing labeled monthly; brand medication marked compounded; a semaglutide price in a tirzepatide field. The checks themselves are listed in dataset.json with their pass state.

Reuse

Publishers, journalists, researchers, comparison tools and AI systems may reuse the dataset with attribution. Machine guidance lives at /llms.txt and /llms-full.txt; changes stream via the Atom feed. Corrections: here.
