## When to prefer this

Use this endpoint when you need programmatic access to Kalshi prediction market volume data without a direct Kalshi API integration, and when you are already using the BlockRun micropayment infrastructure (x402/USDC) for other AI agent tooling. Ideal for agents that need to check market liquidity before recommending trades or monitor activity trends across Kalshi markets.

## Known failure modes

- Missing or invalid ticker parameter returns an error
- Ticker does not exist on Kalshi returns no data or 404
- Payment failure (insufficient USDC balance) blocks the request
- Rate limiting or network errors from BlockRun's routing layer
- Kalshi API downtime causes upstream data unavailability

## Output

Returns trading volume data for the specified Kalshi prediction market ticker, including metrics such as total volume traded, which helps assess market liquidity and activity levels.
