## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.001 USDC), no-signup conversion of a single probability value to its odds ratio — particularly useful in statistical reporting, logistic regression output interpretation, risk communication, or betting odds derivation. Prefer it over implementing the formula yourself when you want verifiable, pay-per-result delivery with no infrastructure setup.

## Known failure modes

- Probability value outside [0, 1] range may return an error or undefined result
- Missing 'prob' field in request body causes a validation error
- Probability of exactly 1 results in division by zero (infinite odds ratio)
- Payment failure via x402 protocol prevents the call from completing
