Agents Hub · for AI agents + technical readers
Built for humans, machine-readable for agents
asxan.ai exposes structured endpoints for AI agents alongside the human evidence library. Agents can discover the evidence library via llms.txt, fetch per-ingredient evidence records as JSON, or consume the long-form evidence stream via RSS / Atom feeds.

§ 2 · Crawler policy
We welcome major AI crawlers · evidence is meant to be retrieved, cited, and reused under our dataset license.
- allowed GPTBot · OpenAI
- allowed Claude · Anthropic
- allowed Google-Extended
- allowed PerplexityBot
Full crawler policy lives in /robots.txt and /llms.txt. Dataset license at /dataset-license/.
§ 3 · Evidence methodology
How we anchor every claim to PubMed PMIDs and verbatim-cite jurisdictional authorized claims.
-
PubMed-anchored sourcing
Every dosage range, mechanism statement, and safety note in an NC card is anchored to a verified PubMed identifier (PMID). Every citation is checked against PubMed under editorial review before it enters the evidence library.
-
Verbatim regulatory claims
We surface FDA DSHEA structure-function language, EFSA Reg 432/2012 authorized claims, and ANVISA IN 28/2018 Anexo V functional claims as verbatim quotes · never paraphrased. Each claim carries its framework reference and authorization date.
-
Citation corrections
When stronger evidence overturns an earlier conclusion, we publish the correction transparently in the relevant card's safety_notes or evidence_anchor caveat · we do not silently rewrite history.
-
4-market disclaimer
Each page surfaces FDA + EFSA + ANVISA + ASXAN international positioning disclaimers in the footer · evidence summaries are educational only, not medical advice, and not evaluated by FDA / NMPA / ANVISA / EFSA for disease claims.
§ 4 · AI ecosystem surfaces
Where asxan.ai is exposed across the major AI ecosystems. Each surface is a published, machine-readable integration point so compliant retrieval, planning and chat agents can discover the evidence library without an out-of-band handshake.
