Example use cases
Example prompt
“Can you pull the liquidity summary for the 'us-election-2024' prediction market and estimate slippage for a $5,000 notional trade — I want to see depth within 1 and 5 cents of the touch and the 24h volume profile across Kalshi and Polymarket?”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/liquidity/:slugWhen to prefer
Use this endpoint when you need execution-quality liquidity analytics — depth, spread, and volume profile — for a specific prediction market. Prefer this over the per-venue implied odds endpoint when your primary concern is trading execution (slippage, fill quality) rather than probability comparison. This is the right choice when sizing a trade and needing to estimate market impact.
