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
Returns weather calibration metrics for the specified station, likely including calibrated atmospheric or temperature parameters used for energy market or quantitative modeling. The response schema is not formally defined, so the exact fields may vary by station.
Example use cases
ERCOT power market weather calibration
“Fetch weather calibration data for station 'KHOU' from Wintergreen — I need it to calibrate my ERCOT merit-order model for Houston-area load forecasting.”
Quant model station data enrichment
“Get the weather calibration output for station 'KORD' from Wintergreen's calibration endpoint so I can enrich my regime-detection model with local atmospheric baselines.”
Duck curve analysis weather input
“Pull the weather calibration data for station 'KSFO' from the Wintergreen x402 weather-calibration API — I'm building a duck curve analysis and need calibrated solar irradiance and temperature baselines for that station.”
Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/quant/weather-calibration?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need weather calibration data for a specific station and are operating in an x402 micropayment-enabled agent environment with USDC on Base. Particularly suited for power market modeling (ERCOT), duck curve analysis, or quant models that require calibrated weather inputs. Prefer this over general weather APIs when you need calibration-specific outputs rather than raw forecasts or observations.
Side effects
- HTTP 402 returned if payment header is missing or invalid — agent must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Invalid or unknown station identifier may return an error or empty response
- USDC balance insufficient on Base (eip155:8453) prevents successful payment
- Payment to wrong address (not 0xAe9834d71F1Bd989A0dc17593451af823E31CeeD) results in failed authorization
- Undefined response schema means output structure may be unpredictable or sparse
