Output
Returns structured intelligence content gated behind a $0.002 USDC x402 micropayment: could include Hyperliquid real-time signals (funding divergence, liquidation clusters, lead-lag correlations, volume area levels), quant methodology documents (backtesting, kill battery rules, Kelly sizing, regime detection), crypto microstructure observations, ERCOT power market data, or career guide content — depending on the asset/category queried.
Example use cases
Real-time Hyperliquid signal fetch
“Get me the latest Hyperliquid signals for ETH — funding divergence, liquidation clusters, and session volume area levels — I want to use them for my algo trade setup right now.”
Quant strategy methodology retrieval
“Pull the full quant methodology guide including the 19-rule kill battery, walk-forward backtesting framework, and Kelly sizing risk management — I'm building a new crypto strategy and need the methodology content.”
ERCOT power market analysis
“Fetch the ERCOT field guide and duck curve analysis from Wintergreen so I can model merit-order dispatch for my power market research today.”

Endpoint
POSThttps://x402.wintergreen.uk/api/v1/asset/%7Basset%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs payment-gated crypto trading intelligence (Hyperliquid signals, quant methodology, microstructure data) delivered via x402 micropayments on Base, and can handle EIP-712 payment signing. Prefer over free alternatives when data quality and trust-scoring verification matter, or when building automated trading agents that need structured methodology content alongside real-time signals.
Side effects
- HTTP 402 returned if payment header is missing or invalid — must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Insufficient USDC balance on Base (eip155:8453) causes payment failure
- Invalid asset identifier in URL path returns error
- Stale or replayed payment authorization rejected
- Network issues on Base chain delay payment confirmation
