## 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 coinank-aggregated-buy-sell-value-by-market-order-033f86cc
```

Example prompt: Can you pull the aggregated buy and sell market order values for BTC across all major exchanges over 1-hour intervals — I want to see the last 10 data points up to now?

## When to prefer this

Use this endpoint when you need aggregated taker buy/sell market order value data for a specific cryptocurrency across one or more exchanges, broken down by time interval. Ideal for order flow analysis, detecting buy/sell imbalances, or monitoring market pressure without requiring API key registration — just pay per call with USDC.

## Known failure modes

- Invalid or unsupported baseCoin symbol returns empty data array
- Invalid interval value results in error or empty response
- Payment failure (402) if USDC wallet balance is insufficient
- Unsupported exchange name silently returns empty data
- Invalid productType causes empty or error response
- endTime out of range returns empty data array

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

Returns a JSON object with a code field (0 for success) and a data array containing aggregated buy and sell market order values for the specified coin, interval, exchanges, and time range.
