How this service works
Odds ratio p/(1−p) from a probability. Call when classic odds-ratio features and diagnostics. Returns odds ratio as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object containing the original probability value (prob), the computed odds ratio (odds_ratio = prob / (1 - prob)), and the schema identifier (delx/util-odds-ratio/v1). For example, prob=0.75 yields odds_ratio=3.
Example use cases
Betting model odds conversion
“My sports prediction model outputs a win probability of 0.6 — convert that to an odds ratio so I can compare it against bookmaker lines.”
Logistic regression output transform
“I have a logistic regression confidence score of 0.85 and need it expressed as an odds ratio for my risk report.”
Clinical trial probability conversion
“The treatment success probability from our study is 0.4 — what's the odds ratio so I can include it in the statistical summary?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/odds-ratioWhen to prefer
Use this endpoint when you need a fast, single-call conversion from a decimal probability to an odds ratio — ideal for agents processing model confidence scores, betting probabilities, or statistical outputs that need to be expressed in odds form. Prefer it over writing inline math when you want a governed, auditable microservice call within a workflow.
Side effects
- Probability value of 1.0 causes division by zero (odds would be infinite)
- Probability value of 0.0 yields odds ratio of 0
- Values outside [0, 1] are not valid probabilities and may return an error or undefined result
- Missing 'prob' field returns a validation error
