## 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 financial-data-x402-prediction-market-data-e507e836
```

Example prompt: What are the current Polymarket odds for 'fed-rate-hike-in-2026'? Pull the live probabilities, volume, and status for that market.

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, political, or crypto events from prediction markets like Polymarket, without needing an API key or subscription — especially when paying programmatically per call via x402 USDC on Base or Solana.

## Known failure modes

- Invalid source name returns an error or empty result
- Unknown market_id returns 404 or empty response
- Payment failure via x402 if USDC balance is insufficient
- Market may be resolved/closed — status field indicates this
- Network latency from upstream prediction market data provider

## How this service works

Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.

## Output

Returns a JSON object containing the market ID, title, data source, current status (active/resolved), outcome names with their current probabilities, closing date, total USD volume, and 24-hour USD trading volume.
