Technical details
Endpoint
POSThttps://prime-api-seven.vercel.app/api/health/body-fatWhen to prefer
Use this endpoint when you need a quick, no-setup body fat percentage estimate without integrating a full fitness platform API. Ideal for health-focused agents that need pay-per-call computation without managing API keys. Best for single-query body composition lookups rather than longitudinal tracking.
Side effects
- Missing required body measurements returns a 400 error
- Out-of-range values (e.g. negative weight) may return a validation error
- Ambiguous or incomplete query string may return a generic or null result
- Service unavailability returns a 500 or payment-gated 402 error
