Biomedical Skills
A collection of Claude Skills for querying public biomedical APIs without paywalls.
Biomedical Skills
Claude Skills for querying public FDA, NIH, and NLM APIs. Every skill uses a free public API. No subscriptions, no paywalls. MIT licensed.
Disclaimer
These skills were built by a federal contracting officer, not a biomedical professional. They query public APIs and return raw data. They do not provide clinical, diagnostic, therapeutic, regulatory, or research advice. Anyone using this data for clinical, pharmacovigilance, regulatory, or research purposes must verify all findings with domain experts and follow applicable standards of practice.
See AI-BOUNDARIES.md for what these tools will not do.
Skills
| Skill | Version | Key | Description |

| PubChem PUG-REST | v1.0 | No key | Chemical compound data. Molecular properties, structures, synonyms, safety/hazard data, bioassay results, cross-references. |
API Keys
Six of the seven skills require no API key. PubMed eUtils accepts an optional NCBI key for higher rate limits (10 requests/sec with a key, 3 requests/sec without). Register at ncbi.nlm.nih.gov/account.
