Example prompt: Stream live trade events for pool 0x4e68Ccd3E89f51C3074ca5072bbAC773960dFa36 on Base so I can monitor what swaps are happening in real time.

## When to prefer this

Use this endpoint when you need real-time, streaming trade data for a specific liquidity pool on a supported blockchain. Ideal for monitoring live swap activity, building trading bots, or tracking price impact of trades as they happen. Prefer this over snapshot/REST endpoints when continuous event-driven updates are required rather than a point-in-time query.

## Known failure modes

- Invalid or non-existent pool address returns an error or empty stream
- Unsupported chain parameter returns an error
- Pool address with no recent trades may return an empty stream
- Network-specific outages may interrupt the stream
- Missing pool path parameter causes a 400 or routing error
- Payment failure (x402) blocks access to the stream
