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-market-roi-calculator-79b097c4 -d '<json body>'
```

Example prompt: I entered a prediction market at 0.4 and it resolved yes — what's my ROI?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.001 USDC), verifiable computation of prediction market ROI for a binary (yes/no) resolved market, especially in an agent workflow where no signup or API key is required and payment is handled via x402 on Base or Solana.

## Known failure modes

- Missing required fields (entry or resolved_yes) returns a validation error
- Entry price of 0 or negative may cause division errors or undefined ROI
- resolved_yes set to false may return ROI of 0 or negative depending on market mechanics
- Network or payment failure via x402 protocol prevents call from completing

## 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 with the computed ROI multiplier (e.g. 1.5 meaning 150% return), the echoed entry price, the resolution status (yes/no), and a schema identifier string (delx/util-market-roi/v1).
