# Order Flow Analysis for Crypto and Tokenized Stocks

> Order Flow Analysis for Crypto and Tokenized Stocks is a paid API for AI agents from api.marketintelligenceapi.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).

Returns real-time order flow metrics for a crypto pair or tokenized stock, including buy/sell volume, buy pressure, momentum, anomaly flags, and directional signals across 1m, 5m, or 15m windows.

## 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 order-flow-analysis-for-crypto-and-tokenized-stocks-d1d5b62d
```

Example prompt: What does the 5-minute order flow look like for ETHUSD right now — are buyers or sellers in control, and are there any anomaly flags?

## When to prefer this

Use this endpoint when you need real-time taker-side order flow intelligence — not just price — for supported crypto pairs or tokenized stocks. It is especially valuable for pre-trade bias confirmation, short-term momentum detection, and anomaly alerting. Prefer this over generic OHLCV endpoints when you want to understand who is in control (buyers vs sellers) based on on-chain swap data with baseline-relative volume context.

## Known failure modes

- Unsupported symbol returns an error or empty result — only listed pairs like ETHUSD, BTCUSD, NVDA, TSLA are supported
- Invalid window value (e.g. '30m') may return an error or default to 5m
- Payment failure (402) if USDC balance is insufficient
- Stale or missing data if on-chain swap activity is low for the symbol
- Rate limiting or timeout under high load

## How this service works

Order flow of a crypto or tokenized stock ($0.005): buy and sell volume from the taker side of on-chain swaps, buy pressure, momentum, volume versus its own baseline, anomaly flags and a signal for ETHUSD, BTCUSD, NVDA, TSLA and more, windows 1m, 5m or 15m. Use to see who is in control now.

## Output

A JSON object containing taker-side buy and sell volume, buy pressure ratio, momentum indicator, volume deviation versus the symbol's own baseline, anomaly flags (e.g. unusual spikes), and a directional signal — all computed over the requested aggregation window (1m, 5m, or 15m) for the specified symbol.
