## 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 agentfeed-orderbook-walls-950def13
```

Example prompt: What are the top 5 bid and ask walls on the SOLUSDT perp right now — show me the USD size of each wall and how far each is from the mid price?

## When to prefer this

Use this endpoint when you need to identify large resting orders (walls) on a specific USDT perpetual orderbook — particularly useful for detecting support/resistance liquidity levels, sizing trades around thick orders, or understanding near-term price barriers. Prefer this over a generic price feed when you need depth and wall structure rather than just a spot or mid price.

## Known failure modes

- Missing or invalid symbol parameter returns an error
- Symbol not a USDT perp (e.g. spot pair) may return empty or error
- top parameter outside 1-15 range may be rejected or clamped
- Payment not sent or x402 payment failure causes 402 response
- Exchange API unavailability causes no data returned

## How this service works

Orderbook walls for any Hyperliquid perp: the largest resting orders on each side of the book, with USD size and distance from mid. Use when you need to answer: Where are the big resting orders?

## Output

Returns a JSON object containing the symbol, current mid price, depth levels scanned, and arrays of bid_walls and ask_walls — each wall entry includes the price level, USD size, and distance from mid. Also includes a paid flag and tool identifier.
