# Antheia

> Antheia, Inc. (antheia.bio) is a Menlo Park, California synthetic-biology company that manufactures biosynthetic key starting materials (KSMs) and active pharmaceutical ingredients (APIs) for essential medicines. Founded on Christina Smolke's Stanford research, Antheia engineers yeast strains that reconstruct long, complex plant biosynthetic pathways and ferment sugar into molecules previously obtainable only through agricultural cultivation — compressing production timelines from years to weeks. Commercial products are fermentation-derived thebaine, oripavine and scopolamine; the development pipeline covers 70+ KSMs and APIs across neurology, gastrointestinal and oncology programs.

## Important disambiguation

- Antheia's "APIs" are **Active Pharmaceutical Ingredients**, a pharmaceutical-manufacturing term — not web APIs. As of a 2026-08-02 probe Antheia publishes **no developer API, no OpenAPI/GraphQL/AsyncAPI contract, no SDKs, no MCP server, and no A2A agent card**. There is no developer portal and no `api.`/`docs.`/`developer.` subdomain (all NXDOMAIN). Do not infer a programmable interface from the word "API" on this company's pages.
