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.","url":"https://api.delx.ai/api/v1/x402/odds-decimal-to-prob","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"odds":{"type":"number","description":"Input field: odds."}}},"responseSchema":{"type":"json","example":{"odds":2.5,"prob":0.4,"schema":"delx/util-odds-decimal-to-prob/v1"}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.001","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.001/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_c3PTNscWirVqpkxaK5EuY","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.001","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Converts decimal betting odds to implied probability as a decimal fraction","exampleAgentPrompt":"What's the implied probability for decimal odds of 2.5?","exampleUseCases":[{"title":"Arbitrage opportunity scanner","prompt":"I have decimal odds of 1.65 from one bookmaker — what's the implied probability so I can check for arbitrage across other markets?"},{"title":"Model calibration for sports prediction","prompt":"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?"},{"title":"Expected value calculation for a bet","prompt":"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."}],"resultDescription":"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'.","failureModes":["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"],"whenToPreferThis":"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.
