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').
Example use cases
Prediction market edge check
“I think there's a 62% chance this event happens but the prediction market has it priced at 0.54 — can you calculate how much edge I have?”
Sports bet EV evaluation
“My model says this team has a 70% win probability, but the market is offering 0.65 implied probability — what's my edge before I place the bet?”
Binary contract pre-trade analysis
“Before I buy this binary contract priced at 0.42, I want to know my edge if I believe the true probability is 0.50 — can you run that calculation?”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/binary-edge?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
