# AI Rook Order Flow Analysis

> AI Rook Order Flow Analysis is a paid API for AI agents from agents.ai-rook.com, paid per call via x402, $0.125/call, status unknown (last checked 2026-09-13).

Fetches real-time crypto order flow data including open interest, cumulative volume delta (CVD), whale CVD sentiment, volume ratio, and market gear for a given trading pair and timeframe

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 ai-rook-order-flow-analysis-d1013f02
```

Example prompt: Pull the current order flow for BTCUSDT on the 15-minute timeframe — I want to see open interest direction, CVD, whale sentiment, volume ratio, and whether the market is in high or low gear.

## When to prefer this

Use this endpoint when an AI trading agent needs real-time order flow intelligence — specifically open interest, CVD, whale activity, and volume ratio — for BTCUSDT or other supported crypto pairs. Prefer this over generic OHLCV or price endpoints when microstructure signals (who is driving price, institutional vs retail flow) matter. Best for momentum-based or flow-based trading strategies requiring a live snapshot without needing historical data storage.

## Known failure modes

- Invalid symbol returns error (only supported pairs accepted)
- Timeframe not in enum [1m,5m,15m,1h,4h] returns 422 validation error
- Bars value outside 1-500 range rejected
- Insufficient USDC balance or failed x402 payment returns 402
- Network or exchange data feed outage may return 503 or stale data
- Base mainnet transaction failure blocks the call

## How this service works

Order flow snapshot — CVD, OI, whale CVD, session levels, proximity to key levels, volume gear ratio. Live from rook-engine MMT WebSocket feed

## Output

Returns a JSON object with open interest value and direction (up/down), CVD value and direction, whale CVD sentiment (bullish/bearish), volume ratio, market gear (high/low), trading symbol, and UTC timestamp — all reflecting real-time market microstructure conditions.
