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 correlation matrix showing pairwise statistical correlations between the requested crypto symbols, likely as a JSON object with symbol-keyed coefficients or a nested matrix structure. Exact response schema is undocumented but expected to reflect quantitative cross-asset relationships derived from Hyperliquid microstructure data.
Example use cases
Crypto portfolio diversification check
“Get me the correlation matrix for BTC, ETH, SOL, AVAX, and ARB — I want to see which of these are too correlated to hold together in my portfolio.”
Pairs trading signal identification
“Pull the correlation data for ETH and SOL — I'm trying to set up a pairs trade and need to confirm they're historically correlated enough to be worth the spread.”
Regime-aware strategy validation
“Give me the cross-asset correlation matrix for BTC, ETH, and BNB so I can check whether my multi-asset quant strategy assumptions still hold in the current market regime.”
Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/quant/correlation-matrixWhen to prefer
Choose this endpoint when you need quantitative cross-asset correlation data for crypto symbols, particularly from Hyperliquid microstructure sources, and you are operating in an x402 micropayment-capable agent environment. Prefer this over generic market data APIs when you need low-cost per-call pricing ($0.001 USDC) and the correlation is specifically needed for quant strategy validation, pairs trading, or portfolio diversification analysis in the crypto domain.
Side effects
- HTTP 402 returned if payment header is missing or malformed — agent must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Invalid or unsupported symbol names may return an error or empty matrix
- Empty symbols parameter likely returns a 400 or empty result
- Network latency or endpoint downtime on the x402.wintergreen.uk domain
- Undocumented response schema means parsing failures are possible if structure changes
