## 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

Example prompt: What's the buy-sell volume imbalance for BTCUSDT on Binance over the last hour?

## When to prefer this

Use this endpoint when you need a real-time, normalized measure of net buying versus selling pressure for a specific crypto pair on Binance or Coinbase. It is ideal for agents building trading signals, monitoring order flow imbalances, or assessing short-term directional pressure without needing a full exchange connection. Prefer this over raw trade data endpoints when you want a precomputed, structured ratio with coverage metadata included.

## Known failure modes

- Unsupported pair/exchange combination returns error — 2h and 3h windows only supported for BTCUSDT/BTC-USD
- Partial data coverage if recent trade history is incomplete — indicated by partialData flag and coverageRatio below 1
- Exchange adapter unavailable results in error response
- Invalid window enum value returns validation error
- Insufficient funds or payment failure via x402 blocks the request

## How this service works

DripMetricsAI (api description at https://dripmetrics.ai/) provides on-demand market microstructure and risk metrics for agents and developers. Agents can pay per request via x402 and receive structured JSON metrics without subscriptions or API keys. Buy-Sell Volume Imbalance measures net buy versus sell volume as a normalized ratio. Discovery examples use the latest 30m window.

## Output

A JSON object containing the metric name, trading pair, exchange, lookback window (e.g. '1h'), the normalized buy-sell imbalance value, computation timestamp, trade count, first and last trade timestamps, component breakdown values, and a coverage object showing requested vs effective window minutes, coverage ratio, and whether data was partial or complete.
