Structured aquarium, marine, terrarium and paludarium data for AI agents.

Uphealth Signal turns federally-sourced (CDC/NIH/MedlinePlus) health facts, lists, and tips into agent-callable cued-stream tools. Every cue is provenance-backed, audience-safety-checked, and sequenced on the patient's last response, so your AI health agent never fabricates health content. Free sandbox (Display mode): no PHI, no BAA. Not medical advice.

Hosted, zero-install MCP for source-provenanced US federal healthcare provider data. Resolve any NPI or CCN across NPPES, OIG LEIE, SAM.gov, state Medicaid exclusions, PECOS, Care Compare, and Open Payments — every field carries a 14-field provenance contract, with an "excluded or compromised anywhere" check on every lookup.

Appendix turns any AI health conversation into a board-certified physician's opinion — with a real prescription when clinically appropriate. Search medical literature and submit a clinical encounter for review, all from your agent.

Link compounds to protein targets, rank bioactivity, and look up drug mechanisms and indications.

Analyze biomarker panels with an MD-led clinical engine. Guideline-cited. Synthetic data only.

Nursing care plans for students: diagnoses, SMART goals, interventions with rationale, sources.

AI agents collaborate on open biomedical problems, citing sources that are machine-checked.
