## 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 predict-polymarket-event-odds-order-book-trades-by-event-id-46935b25
```

Example prompt: What are the current Polymarket odds and order book for the 2024 US presidential election event? Pull the live YES/NO probabilities and recent trades for that market.

## When to prefer this

Use this endpoint when an agent needs live, per-event prediction-market data from Polymarket — including current odds, order-book depth, and trade history — for a specific known event ID or slug. Prefer this over a keyword search endpoint when you already have the event identifier. Ideal for forecasting agents, trading bots, and research pipelines that need real-time market-implied probabilities without requiring API key management.

## Known failure modes

- Invalid or unknown event ID/slug returns 404 or empty result
- Payment failure (insufficient USDC balance) returns 402 Payment Required
- Network timeout if Polymarket data feed is slow
- Malformed query parameter returns 400 Bad Request
- Event has been resolved/closed — may return stale or no active order book data

## How this service works

Predict gives AI agents live prediction-market odds, order-book depth and recent trades across thousands of markets (Polymarket) in one keyless call. Pay per call in USDC — no demo, no API key. For forecasting, trading and research agents.

## Output

Returns live prediction-market data for the specified event including current YES/NO odds (implied probabilities), order-book bid/ask depth across outcome tokens, and a feed of recent trades — sourced in real time from Polymarket's CLOB.
