How this service works
Convert American odds into implied probability. Call when US sportsbook-style odds into probability for models. Returns implied probability from American 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
A JSON object containing the original American odds integer, the computed implied probability as a decimal between 0 and 1, and a schema identifier string (e.g. {"odds": -150, "prob": 0.6, "schema": "delx/util-odds-american-to-prob/v1"}).
Example use cases
Betting model feature engineering
“I need to feed implied win probabilities into my model — can you convert these American odds to probabilities: -110, +230, and -300?”
Arbitrage break-even check
“My sportsbook is showing -180 on one side and +155 on the other — what are the implied probabilities so I can check for an arb?”
Expected value calculation for a wager
“I'm looking at a bet with odds of +275 — what's the implied probability so I can compare it to my estimated true probability?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/odds-american-to-probWhen to prefer
Use this endpoint when you need a fast, cheap ($0.001 USDC), deterministic conversion of American (moneyline) odds to implied probability inside an automated agent workflow — particularly when you want a standardized output schema rather than implementing the formula yourself. Prefer this over manual calculation when building pipelines that process many odds values reliably and need auditability via the schema field.
Side effects
- Missing or non-integer odds field returns a validation error
- Odds value of 0 or between -99 and +99 may be invalid American odds and could return an error or unexpected result
- Network timeout or service unavailability returns a 5xx error
- Malformed JSON request body returns a 400 error
