# Delx Commerce — Binary Edge Calculator

> Delx Commerce — Binary Edge 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 edge (expected value advantage) for a binary market given a true probability and a market price

## Facts

- Price: $0.001/call
- Payment: x402

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-binary-edge-calculator-f08ea0fe -d '<json body>'
```

Example prompt: I think this binary market has a true probability of 55% but it's currently priced at 48% — what's my edge?

## When to prefer this

Use this endpoint when you need a fast, cheap, single-call computation of binary market edge — particularly in agentic trading or analysis pipelines where you have your own probability estimate and want to compare it against a market price. At $0.001 USDC per call with no signup required and verifiable delivery via x402, it's ideal for high-frequency automated checks before placing binary contract positions.

## Known failure modes

- Missing required fields (true_prob or market_price) returns a validation error
- Values outside [0,1] range for probabilities may produce nonsensical or error responses
- Payment failure via x402 protocol prevents the call from being processed
- Network timeout if the endpoint is temporarily unavailable

## 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 computed edge (a float representing the probability-weighted advantage over the market price), along with the input true_prob and market_price echoed back, and a schema version identifier (e.g. 'delx/util-binary-edge/v1').
