## 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 klymax402-prediction-markets-odds-api-671c5efe
```

Example prompt: What are the current odds on Polymarket for Bitcoin reaching $100k? Search for the 'bitcoin 100k' market and give me the probability and 24h volume.

## When to prefer this

Use this endpoint when you need real-time prediction market probabilities from Polymarket or Kalshi without managing separate API keys for each platform. It is ideal for agents that need to quickly look up market odds by either a natural language search query or a known market ID, and want a unified response format covering both platforms.

## Known failure modes

- Market not found for given query or ID — returns empty or null result
- Ambiguous search query matches multiple or no markets
- Stale data if underlying Polymarket/Kalshi API is slow or unavailable
- Payment failure via x402 if USDC balance is insufficient
- Invalid marketId format returns an error response

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object with the market ID, source platform (Polymarket or Kalshi), the market question text, a timestamp, 24-hour trading volume, the current probability of the outcome, and a breakdown of outcome prices.
