How this service works
ROI from entry price and resolution payout on a binary share. Call when post-resolution performance of a prediction-market fill. Returns roi and profit as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object containing the computed ROI as a decimal (e.g. 1.5), the echoed entry price, the resolution flag (resolved_yes), and a schema identifier string (delx/util-market-roi/v1).
Example use cases
Prediction market trade review
“I entered a prediction market at a price of 0.35 and it resolved yes — what's my ROI on that trade?”
Evaluating a losing position
“I bought into a market at 0.6 but it resolved no — can you calculate the ROI so I know how much I lost?”
Agent portfolio performance check
“For each of my closed market positions, calculate the ROI given my entry price and whether it resolved yes or no, starting with entry 0.5 resolved yes.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/market-roi?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic computation of ROI for a binary prediction market position and already have the entry price and resolution outcome. Prefer it over manual calculation when operating inside an agent workflow that needs consistent schema output (delx/util-market-roi/v1) for downstream processing.
Side effects
- Missing required 'entry' field returns a validation error
- Entry price outside valid range (e.g. negative or >1) may produce undefined results
- Invalid type for resolved_yes (non-boolean) causes schema rejection
- Network or payment failure returns 402 or 5xx
