## 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 prediction-market-volume-trade-count-by-exchange-time-bucketed-c35f067e
```

Example prompt: Show me the hourly prediction market trading volume and trade counts broken down by exchange from January 1, 2025 at 00:00 UTC to January 7, 2025 at 00:00 UTC, using 1-hour buckets (3600000 ms intervals).

## When to prefer this

Use this endpoint when you need per-exchange granularity of prediction market volume and trade activity over a custom time range. Prefer this over the total-volume endpoint when you need to compare exchanges head-to-head or identify which platform is driving market activity. Best for analytics, dashboards, and monitoring trading concentration across prediction market venues.

## Known failure modes

- Missing required query params (from, to, interval) returns a 400 error
- Invalid ISO-8601 timestamp format causes a parsing error
- Interval value not in milliseconds or set to zero/negative causes bad request
- Time range too large or interval too small may result in timeout or truncated response
- Payment not attached or insufficient USDC balance returns 402 Payment Required
- Future timestamps may return empty buckets

## How this service works

Time-bucketed prediction market volume and trade-count by exchange.

## Output

A time-series dataset of prediction market activity segmented by exchange, where each bucket contains the trading volume (USD) and trade count for that exchange during the interval. Data is organized by time bucket and exchange identifier, enabling cross-platform volume comparisons over the requested period.
