Example prompt: What's the live trading volume right now for Polymarket event ID 12345? Show me the total and a breakdown by market.

## When to prefer this

Use this endpoint when you need real-time, per-event trading volume data from Polymarket, especially when you want a breakdown of volume across individual markets within an event. Prefer this over open interest (Oi) when you want to measure trading activity rather than outstanding positions.

## Known failure modes

- Missing or invalid event ID returns a validation error
- Non-existent event ID may return empty array or error
- Event ID below minimum (1) is rejected by schema validation
- Network or upstream Polymarket API downtime may cause request failure

## How this service works

Get live volume for an event.

## Output

Returns an array containing a total volume figure and an array of individual market objects, each with a market address (0x-prefixed 64-hex string) and its corresponding volume value. This gives a complete picture of live trading activity across all markets within the event.
