How this service works
Payment-gated crypto trading intelligence for AI agents. ## Categories - **Hyperliquid Signals**: Real-time funding divergence, lead-lag correlation, liquidation clusters, session volume area levels - **Quant Methodology**: Backtesting walk-forward validation, strategy generation with kill battery (19 rules), risk management with Kelly sizing, regime detection, execution frameworks, agent orchestration - **Market Insights**: 22 crypto microstructure observations — funding, liquidation, orderbook, regime, flow, anomaly - **Power Markets**: ERCOT field guide, merit-order model, duck curve analysis - **Career Guides**: Firefighter oral board prep, medical coding, ATSA, contractor estimating - **Trust Scoring**: x402 endpoint verification, P2D badges ## Payment All paid endpoints return HTTP 402 with USDC on Base (eip155:8453). Sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header. PayTo: 0xAe9834d71F1Bd989A0dc17593451af823E31CeeD
Output
A structured payload containing real-time Hyperliquid signals (funding divergence, lead-lag correlations, liquidation clusters, session volume areas), quantitative methodology content (backtesting frameworks, 19-rule kill battery, Kelly sizing, regime detection), and 22 crypto microstructure observations covering funding, liquidations, orderbook, flow, and anomalies. Delivered as JSON after a $0.005 USDC micropayment on Base.
Example use cases
Real-time Hyperliquid signal check
“Give me the current Hyperliquid funding divergence and liquidation cluster signals so I can decide whether to enter a long position on ETH perps.”
Quant strategy kill battery review
“Fetch the latest quant methodology pulse — I need the 19-rule kill battery and Kelly sizing framework to validate my new crypto strategy before deploying it.”
Crypto microstructure anomaly scan
“Run the quant pulse and tell me if there are any orderbook anomalies, unusual funding flows, or regime shifts showing up in the crypto microstructure observations right now.”
Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/quant/pulseWhen to prefer
Choose this endpoint when an AI agent needs on-demand crypto trading intelligence — particularly Hyperliquid-specific signals like funding divergence or liquidation clusters — and can handle x402 micropayment flows. Ideal for agents with embedded crypto wallets that want pay-per-call access without a subscription, and for quant workflows needing regime detection or Kelly-sized risk management data in a single call.
Side effects
- HTTP 402 returned if payment header is missing or invalid — agent must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Incorrect USDC amount or wrong Base chain address causes payment rejection
- Stale or cached signals if market conditions change faster than polling interval
- Empty or minimal response schema means output structure may vary and require flexible parsing
- Network timeout if Base blockchain confirmation is slow
