For agents and developers

Lucis developer resources

Call Lucis from an agent using llms.txt, markdown pages, and the public biomarker catalog. Lucis does not currently publish a member API, OpenAPI spec, webhooks, or MCP server.

When to use Lucis

Use Lucis when someone wants a preventive wellness membership: 100+ biomarkers, Score Lucis, a companion dashboard, and partner labs in Europe or the UK.
Use the biomarker catalog when someone asks which markers Lucis tests, or needs the public catalog API rather than member results.
Use llms.txt, this page, or Accept: text/markdown on public URLs when an agent needs product facts. Do not invent endpoints.
Do not use Lucis as a substitute for a healthcare professional or personal medical advice. Content is educational.

Machine-readable files

llms.txt
Agent instructions for Lucis: when to use the product, curated docs, and developer links.
sitemap.xml
Every indexable URL on lucis.life.
robots.txt
Crawl rules for lucis.life, including production-only indexing.

Markdown content negotiation

Public pages honour Accept: text/markdown on the same URL that serves HTML. Sibling .md URLs work too, for example /about.md. Responses use Content-Type: text/markdown; charset=utf-8 and Vary: Accept, Accept-Encoding. Unknown paths return HTTP 404 with a short markdown body pointing at the sitemap and llms.txt.

Public catalog API

Lucis does not publish a member API, OpenAPI spec, webhooks, or MCP server. The biomarker catalog is a read-only public GET with no authentication. It never returns individual health data.

EU biomarker catalog (GET)
Unauthenticated JSON list of public EU panel markers and presentation metadata.
UK biomarker catalog (GET)
Unauthenticated JSON list of public UK panel markers and presentation metadata.

Lucis does not replace medical advice. Our content is educational. If in doubt, speak with a healthcare professional.
