How this service works
Convert decimal odds into implied probability (1/odds). Call when normalizing book odds into agent probability space. Returns implied probability from decimal odds 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 decimal odds, the computed implied probability as a decimal (e.g. 0.4 for odds of 2.5), and a schema identifier string 'delx/util-odds-decimal-to-prob/v1'.
Example use cases
Arbitrage opportunity scanner
“I have decimal odds of 1.65 from one bookmaker — what's the implied probability so I can check for arbitrage across other markets?”
Model calibration for sports prediction
“My sports model outputs win probabilities, but the exchange shows decimal odds of 3.2 — can you convert that to an implied probability so I can compare it to my model's output?”
Expected value calculation for a bet
“The odds on this match are 2.1 in decimal format — convert that to an implied probability so I can figure out if the bet has positive expected value given my estimated 55% chance of winning.”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/odds-decimal-to-probWhen to prefer
Use this endpoint when you need a fast, reliable micro-computation to convert a single decimal odds value to implied probability within an agent workflow — for example, before computing expected value, comparing markets, or calibrating a prediction model. It is ideal when you want a governed, auditable service call rather than computing 1/odds inline, ensuring consistent handling and schema-versioned output.
Side effects
- Missing or non-numeric odds value returns a validation error
- Odds value of zero or below one would produce mathematically invalid probabilities
- Malformed request body or wrong content type may return a 400 error
