# AgentFeed Orderbook Imbalance

> AgentFeed Orderbook Imbalance is a paid API for AI agents from x402.ochinimus.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).

Returns resting bid/ask liquidity in USD within a configurable BPS window around mid-price for any USDT perpetual, plus the imbalance ratio and a directional skew label.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-imbalance-9e71daf2
```

Example prompt: What's the orderbook imbalance on SOLUSDT right now — check within 50 bps of mid and tell me if it's bid-heavy or ask-heavy and by how much.

## When to prefer this

Use this endpoint when you need a fast, quantified snapshot of resting orderbook liquidity imbalance for a specific USDT perpetual — particularly when assessing directional bias, support/resistance context, or pre-trade market structure. Prefer it over raw exchange APIs when you want a normalized, multi-field summary (ratio + skew label + USD amounts) in a single call, paid per-use with no subscription required.

## Known failure modes

- Invalid or unsupported symbol returns an error — only USDT perp pairs are supported
- BPS value outside the 5–500 range may be rejected or clamped
- Payment not settled (402 response) if x402 payment header is missing or rejected
- Stale or missing exchange data may reduce accuracy of liquidity figures
- Network timeouts possible during high-volatility periods

## How this service works

Orderbook imbalance for any USDT perp: resting bid and ask liquidity in USD within ±N bps of mid, the ratio between the two sides, and a skew read. Use when you need to answer: Which side of the book holds more resting liquidity?

## Output

Returns a JSON object with: the symbol, mid price, window in BPS, total bid-side USD and ask-side USD within that window, the ratio of bid to ask (imbalance_ratio), and a human-readable skew label (e.g. 'bid_heavy (support below)'). Includes a caveat that data reflects visible resting orders only and may be spoofed.
