Example use cases
Real-time liquidation cluster signal
“Get me the liquidation clusters insight from Wintergreen right now — I want to see where the major liquidation levels are sitting on Hyperliquid so I can plan my entries.”
Quant strategy backtesting methodology
“Fetch Wintergreen's walk-forward backtesting methodology insight for me, including the 19-rule kill battery — I'm building a new systematic strategy and need the full framework.”

POSThttps://x402.wintergreen.uk/api/v1/insights/%7Binsight_title%7DWhen to prefer
Choose this endpoint when an AI agent needs on-demand, low-cost ($0.05) access to curated crypto trading intelligence — specifically Hyperliquid signals, quantitative methodology, or crypto microstructure observations — without a subscription. Ideal for agents that need pay-per-use access to specialized trading research that isn't available through free market data APIs. Prefer over general market data APIs when the agent needs interpreted, actionable signals rather than raw price data.
Side effects
- HTTP 402 returned when payment header is missing or invalid — agent must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Invalid or unknown insight_title path parameter returns 404 — agent must use exact title slug
- Insufficient USDC balance on Base chain causes payment failure
- Network latency or Base chain congestion may delay payment confirmation
- insight_title URL encoding issues if title contains special characters
