# Delx Commerce — Independent Parlay Probability Calculator

> Delx Commerce — Independent Parlay Probability Calculator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Computes the combined probability of a parlay (multi-leg) bet assuming all legs are statistically independent

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-independent-parlay-probability-calculator-7e442ac7 -d '<json body>'
```

Example prompt: Calculate the combined parlay probability for three independent legs with probabilities 0.5, 0.4, and 0.6 — assuming they're all independent of each other.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
