## 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 wickedapi-order-book-endpoint-d3220e56
```

Example prompt: Pull the current order book for BTC/USDC so I can see the bid and ask depth right now.

## When to prefer this

Choose this endpoint when you need real-time bid/ask depth (order book snapshot) for a specific trading pair, especially in an agent context where per-call micropayments via x402/USDC are preferred over a subscription. It is part of a broader 23-endpoint trading data platform covering crypto and stock data, so it integrates naturally with sibling endpoints for prices, OHLCV, indicators, and AI momentum scores.

## Known failure modes

- Missing or invalid symbol parameter returns an error or empty data object
- Unsupported trading pair returns 404 or empty result
- Rate limit exceeded returns 429 or payment required response
- x402 payment failure if USDC balance is insufficient
- Network timeout if exchange data feed is slow
- Stale data if the upstream exchange feed is delayed

## How this service works

Agent-ready trading & market-data API: prices, indicators, prediction markets, macro, and an AI momentum score. Pay per call with x402 (USDC) or an API key.

## Output

Returns a JSON object with order book data including arrays of bids and asks (price levels and quantities) for the requested trading pair, along with a metadata timestamp indicating when the snapshot was taken.
