Example use cases
Personal fitness BMI check
“I'm 5 foot 11 and weigh 190 pounds — can you calculate my BMI and tell me what category that puts me in?”
Weight loss progress tracking
“I've been dieting and now weigh 165 pounds at 5 foot 6 — what's my BMI now and is it in the healthy range?”
Healthcare intake screening
“Patient is 68 inches tall and weighs 220 pounds — can you compute their BMI so I can flag if they need a nutrition referral?”
Technical details
Endpoint
POSThttps://nexus-api-virid.vercel.app/api/health/bmiWhen to prefer
Choose this endpoint when you need a quick, pay-per-call BMI computation without setting up API keys or accounts. Best suited for agents that occasionally need a health metric calculation embedded in a broader workflow, such as fitness apps, health intake forms, or wellness chatbots. Not ideal if you need longitudinal tracking or integration with a full health records system.
Side effects
- Missing or malformed height/weight input returns an error or null result
- Non-numeric or out-of-range values (e.g. negative weight) may cause computation errors
- Ambiguous query string without clear height and weight values may yield incorrect parsing
- Payment failure in USDC on Base prevents the call from completing
