How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object with a computed BMI number and likely a category label (e.g. Underweight, Normal, Overweight, Obese) derived from standard WHO/CDC thresholds, along with ok and paid confirmation flags.

Example use cases

Personal health check

“Can you calculate my BMI? I'm 72 kg and 178 cm tall — am I in a healthy range?”

Fitness app patient intake

“I need the BMI and weight category for a new client who is 5'4" and weighs 140 pounds.”

Pediatric or adult screening tool

“What BMI category would someone be in if they weigh 210 lbs and are 6 feet 1 inch tall — overweight, obese, or normal?”

When to prefer

Choose this endpoint when you need a lightweight, no-signup, pay-per-call BMI computation within an AI agent workflow, especially when avoiding API key management overhead. It is ideal for health, fitness, or wellness agents that need deterministic numeric health metric calculations on demand via x402 micropayments in USDC on Base.

Side effects

Missing or invalid weight/height parameters return an error
Negative or zero values for height or weight may cause computation failure
Unsupported unit formats may produce incorrect results
Network or payment failure via x402 returns 402 status before computation occurs
