Data
Open dataset
The encyclopedia's 290 compounds as JSON and CSV, and a static JSON API with one file per compound. Free to reuse, including commercially, with attribution under CC BY 4.0.
Version 2026-10-02.cc01c521: the date of the newest review in the records and a fingerprint of their content, so the version changes whenever the data does, and only then. These files are rebuilt from the same data as the pages, and a release check fails if they drift apart.

Typical doses are reported with their source (prescribing label, human study or community report), as on the site; they describe what a source states and are not recommendations.
Static API
/data/v1/index.json lists every compound with its page and its API file. Each compound is at /data/v1/compounds/<id>.json, for example bpc-157.json. The files are static, need no key, and can be read from any site.
Schema v1 is stable: new fields may be added, and anything that would break a reader would go to /data/v2/, with v1 left in place.
