How this service works
Real-time multi-DEX aggregated crypto market data. Pay per request with USDC on Base via x402 protocol.
Output
Returns a JSON object containing the queried symbol, the current market price, a cascade_risk classification string (e.g. low/medium/high), and an array of liquidation_clusters representing price levels where leveraged positions are concentrated and at risk of being liquidated.
Example use cases
Pre-trade liquidation zone check
“Before I open a long position on ETH, can you pull up the current liquidation heatmap so I can see where the big liquidation clusters are and whether there's a cascade risk near the current price?”
Monitoring SOL for cascade risk
“Keep an eye on SOL's liquidation heatmap and let me know if the cascade risk level changes — I want to know if we're building up dangerous liquidation clusters.”
DeFi risk assessment for portfolio hedging
“I'm trying to hedge my BTC position — can you get me the liquidation cluster data across DEXes so I can see which price levels have the most concentrated liquidation risk?”
Technical details
Endpoint
GEThttps://api.foursec.xyz/liquidation/heatmap/%7Bsymbol%7DWhen to prefer
Choose this endpoint when you need real-time, multi-DEX aggregated liquidation heatmap data for a specific crypto asset, particularly when assessing cascade liquidation risk before entering or exiting a leveraged position. Prefer this over generic price feeds when liquidation cluster density and cascade risk are the primary concern. The pay-per-request x402 model makes it suitable for on-demand queries without subscription overhead.
Side effects
- Invalid or unsupported symbol returns an error or empty response
- Payment failure via x402/USDC results in 402 Payment Required
- Symbol path parameter missing causes a 404 or 400 error
- Network latency or DEX data feed delays may result in stale data
- Rate limiting if too many requests are sent in quick succession
