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 echoed input probability, the schema identifier ('delx/util-binary-fair-price/v1'), and the computed fair price (a decimal number equal to the probability, representing the expected value of the binary outcome in USDC terms).
Example use cases
Prediction market settlement pricing
“I need to calculate the fair price for a binary prediction market contract where the event has a 65% chance of happening — what should the settlement price be?”
Probabilistic bet fair value
“Before I place a bet on a binary outcome, can you tell me the fair price I should pay given the event has a 0.82 probability of occurring?”
Agent decision weighting
“I'm building an automated decision pipeline — can you compute the fair price for a binary outcome with probability 0.15 so I can weight my options correctly?”

Use this endpoint when you need a quick, verifiable, mathematically grounded fair price for a binary (yes/no) outcome given a known probability — particularly in agent workflows involving prediction markets, probabilistic decision-making, or automated betting/settlement. It is pay-per-result with no signup and verifiable delivery via x402, making it ideal for trustless agent pipelines.
Side effects
- Missing 'prob' field returns a validation error
- Probability outside [0, 1] range may return an error or undefined behavior
- Payment not provided or insufficient USDC results in x402 payment required response
- Network timeout if the service is temporarily unavailable
