## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability gocreative-bmi-calculator-ffc74208
```

Example prompt: Can you calculate the BMI for someone who is 5 feet 10 inches tall and weighs 185 pounds, and tell me what category that falls into?

## When to prefer this

Choose this endpoint when an AI agent needs a quick, pay-per-call BMI computation without requiring API keys or signup — ideal for health, fitness, or medical workflow agents that need on-demand body mass index calculations for individual users, with payment handled automatically via USDC on Base (x402).

## Known failure modes

- Missing or malformed input argument returns an error
- Input not parseable as height/weight combination returns bad request
- Payment of $0.005 USDC not provided or fails causes 402 Payment Required
- Unsupported unit format (e.g. ambiguous metric vs imperial) may return error or unexpected result

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns the computed BMI numerical value along with a classification category such as underweight, normal weight, overweight, or obese based on standard WHO/CDC BMI thresholds.
