Endpoint
POSThttps://omni-api-cyan.vercel.app/api/health/body-fatWhen to prefer
Use this endpoint when you need a quick, pay-per-call body fat percentage estimation without setting up a dedicated health API account. It is suitable for fitness apps, wellness agents, or personal health tracking workflows that occasionally need body composition calculations and prefer USDC micropayment billing over subscription models.
Side effects
- Missing required query/input field returns validation error
- Malformed or non-numeric measurement values may cause computation errors
- Out-of-range values (e.g. negative weight) may return error or implausible results
- Payment failure via x402 results in 402 response before computation occurs
