# Cryptyx Taker Flow – Buy/Sell Volume & Aggressor Ratio

> Cryptyx Taker Flow – Buy/Sell Volume & Aggressor Ratio is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns aggregated taker buy and sell volume in USD plus buy-sell ratio for a given crypto asset, enabling aggressor-side pressure analysis independent of price.

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 cryptyx-taker-flow-buy-sell-volume-aggressor-ratio-95327973
```

Example prompt: What's the taker buy/sell flow and aggressor ratio for BTC right now — is there more buying pressure or selling pressure driving the tape?

## When to prefer this

Use this endpoint when you need real-time aggressor-side order flow analysis for a specific crypto asset — particularly for high-frequency entry timing, tape reading, or when you want a leading indicator that may precede price moves by hours. Prefer this over price-only or OHLCV endpoints when flow imbalance and buy-sell pressure are the signals of interest.

## Known failure modes

- Unknown or unsupported asset symbol returns empty flows array or 404
- Missing asset query parameter may return all assets or an error depending on API behavior
- Service unavailable or rate limit exceeded returns 402/429 or 5xx
- Stale data if upstream exchange feeds are delayed

## How this service works

CRYPTYX | institutional-grade crypto intelligence: 150+ signals, 440+ metrics, 200+ assets. | Last N days (default 30, max 365) of taker aggressor flow per asset, split into spot and futures arrays of recent rows with asof_day, asset, taker_buy_usd, taker_sell_usd, bs_ratio - pass-through of compat.spot_taker_bs_1d and compat.fut_takerbs_1d with no z-score, FLOW factor t-score, regime label, or signal context. Feeds custom flow models on CRYPTYX cleaned spot and perp taker tape

## Output

A JSON array of flow objects, each containing asset symbol, taker buy volume in USD, taker sell volume in USD, and the buy-sell ratio (bs_ratio). For example: BTC with $500M buy volume, $480M sell volume, and a bs_ratio of 1.04 indicating net buying aggression.
