Evidence-cited synthesis. Condition-specific.
One API call returns a risk level, synthesis paragraph, cited recommendations, 10 peer-reviewed papers, and the full environmental snapshot — grounded in 400,000+ PubMed articles. For digital health apps and employee wellbeing platforms.
For integration evaluation and prototyping only. Not for production use. Tell us your use case when you request access — we'll issue a key and a quick-start guide the same day.
For startups building a single-condition integration. A migraine tracker. An asthma diary. A pollen allergy app. Build, ship, and validate with real users.

Why sensitivity gating — not call volume gating?
A migraine tracker doesn't need cardiovascular scoring. An asthma app doesn't need sleep synthesis. Sensitivity gating means you pay for what you actually use — and it reflects who your product is for, not just how many calls you make.
Need more than 3 sensitivities? That's Enterprise — talk to us.
What no one else provides.
