## 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-event-30d30b98
```

Example prompt: What are the current Polymarket odds and trading volume for the 'next-prime-minister-of-ethiopia' event? I want to see all the outcomes and their probabilities.

## When to prefer this

Choose this endpoint when you need real-time prediction market probability and volume data for a specific named event (identified by its slug), paid per-call without subscriptions or API keys. It is ideal for agents that need to programmatically ingest market sentiment from Polymarket-style sources on a per-query basis using USDC micropayments over x402.

## Known failure modes

- Invalid or unknown slug returns a 404 or empty response
- Payment failure if USDC balance is insufficient or x402 handshake fails
- Event may have resolved, returning a non-active status with stale probabilities
- Slug format mismatch (e.g. URL encoding issues with special characters)
- Upstream Polymarket data unavailable or delayed

## 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

A JSON object containing the event's title, source (e.g. Polymarket), status (active/resolved), a list of outcomes each with a label, market ID, USD volume, and probability, plus the event's close date and total outcome count.
