How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the schema identifier, the overround (as a decimal representing the bookmaker's total margin), and an array of two fair implied probabilities for side A and side B after the vig has been removed.
Example use cases
Sports betting edge analysis
“I've got odds of 2.10 for the home team and 1.80 for the away team on this soccer match — can you strip the vig and tell me what the true fair probabilities are and how much overround the bookmaker is charging?”
Comparing books for best value
“The odds at one sportsbook are 1.91 and 1.91 for a coin-flip line. Strip the vig and give me the fair probabilities so I can see how much margin they're taking.”
Arbitrage opportunity check
“I have decimal odds of 2.05 for side A and 2.00 for side B — what's the overround here, and what are the fair no-vig implied probabilities for each side?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/odds-vig-strip?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, single-call computation to strip bookmaker vig from a two-outcome market expressed in decimal odds. It is ideal for agents doing real-time betting analysis, value-hunting, or arbitrage screening where you need the fair probability quickly without building the math yourself. Prefer this over manual calculation when operating in an automated agent pipeline that already supports x402 micropayments on Base or Solana.
Side effects
- Missing odds_a or odds_b fields returns a validation error
- Odds values of 1.0 or below (invalid decimal odds) may produce division errors or nonsensical results
- Odds implying negative overround (odds too generous) may return unexpected values
- Payment failure or insufficient USDC balance returns 402 Payment Required
