## 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 lukka-prediction-markets-total-volume-e2a6896e
```

Example prompt: Pull the total prediction market trading volume from Lukka from January 1, 2025 to June 1, 2025 in daily buckets (86400000 ms intervals) so I can see how activity trended across exchanges like Polymarket.

## When to prefer this

Use this endpoint when you need aggregated historical trading volume for prediction market exchanges over a custom time range with configurable bucket granularity. Prefer this over individual contract-level data when you want exchange-wide or platform-wide volume trends.

## Known failure modes

- Missing required query params (from, to, interval) returns a 400 error
- Invalid ISO-8601 timestamps cause parsing errors
- Interval value not a valid millisecond bucket size may return empty or malformed data
- Date range too large may result in timeout or rate limiting
- Payment not completed (x402) returns 402 Payment Required

## How this service works

Time-bucketed total prediction-market volume across all exchanges.

## Output

A JSON array of time-bucketed volume records, each containing a UTC timestamp, source ID, exchange entity code (e.g. POLYMARK), exchange name (e.g. Polymarket), and total volume in USD for that bucket. Also includes a total count of records and a dataType identifier.
