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 number of legs (n), the input probability array (probs), a schema identifier (delx/util-parlay-prob-indep/v1), and the computed parlay probability (parlay_prob) as a decimal between 0 and 1, representing the product of all independent leg probabilities.
Example use cases
Sports parlay bet probability check
“I'm thinking of betting a 3-leg parlay — the first team has a 60% win probability, the second has 55%, and the third has 70%. Assuming these are independent, what's the overall probability all three legs hit?”
Multi-event risk assessment
“I have four independent risk events each with probabilities 0.1, 0.2, 0.15, and 0.05. What's the probability that all four of them occur simultaneously?”
Combined likelihood for independent model outputs
“My three classifiers independently predict positive outcomes with probabilities 0.8, 0.75, and 0.9. What's the joint probability all three classifiers agree and are correct?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/parlay-prob-indep?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, cheap, verifiable computation of the joint probability of multiple independent events — especially in betting, risk modeling, or multi-classifier scenarios. It is ideal when you have already determined individual leg probabilities and want the combined parlay probability without writing custom code. Prefer this over a general-purpose computation tool when you want pay-per-result pricing with no signup overhead and cryptographic verifiability via USDC on Base or Solana.
Side effects
- Invalid or missing probs array returns an error
- Probabilities outside [0, 1] range may produce unexpected results
- Empty array may return an error or undefined result
- Non-numeric values in the probs array will likely cause a validation error
- Payment failure via x402 prevents the call from being processed
