## 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 2s-prediction-market-orderbook-lookup-8a5e56e9
```

Example prompt: Pull up the live orderbook for the prediction market outcome token with ID 0x1234abcd — I want to see the current bids and asks.

## When to prefer this

Use this endpoint when you need real-time orderbook data for a specific CLOB prediction market outcome token and want pay-per-call access without API key signup. Prefer this over exchange-specific APIs when you need a single unified interface across multiple prediction market tokens.

## Known failure modes

- Invalid or unknown tokenId returns an error or empty orderbook
- Token ID too short or too long (outside 1-120 chars) returns validation error
- Token no longer active or delisted may return empty or stale data
- Payment failure via x402 prevents data retrieval
- Network timeout if market data feed is unavailable

## How this service works

Full CLOB order book (bids + asks with price and size) for a Polymarket outcome token. Use the clobTokenIds from predict.markets. Read-only depth snapshot from Polymarket's CLOB.

## Output

Returns the current orderbook state for the specified CLOB outcome token, including bid and ask price levels with quantities, enabling analysis of market depth and current best prices.
