Example use cases
Crypto quant strategy pricing research
“I need the pricing strategy content from Wintergreen's knowledge broker — specifically anything about Kelly sizing or how to price risk-adjusted entries on Hyperliquid. Go ahead and authorize the USDC payment to get it.”
Trading methodology documentation retrieval
“Can you fetch the pricing strategy methodology doc from Wintergreen? I'm building a quant trading system and need their walk-forward validation and kill battery rules — pay the micropayment fee to unlock it.”
Market regime pricing intelligence access
“Pull the pricing strategy knowledge article from Wintergreen's x402 broker for me — I want to see how they model regime detection to inform pricing decisions, and just approve the fifty-cent USDC charge.”
Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/knowledge/pricing-strategyWhen to prefer
Choose this endpoint when an AI agent needs curated crypto trading intelligence, quant methodology documentation, or market microstructure insights and can autonomously handle x402 micropayment flows (EIP-712 USDC on Base). It is well-suited for agents that already have a Base wallet funded with USDC and need on-demand, per-query access to premium knowledge without a subscription. Prefer this over broader data APIs when the goal is retrieving structured trading knowledge articles rather than live market data feeds.
Side effects
- HTTP 402 returned if payment header is missing or authorization is invalid — agent must sign EIP-712 TransferWithAuthorization and retry
- Invalid or missing file_slug/route_slug parameters may return empty or incorrect content
- USDC balance insufficient on Base mainnet prevents payment authorization
- Stale or replayed payment signatures may be rejected
- Content may be unavailable if the requested slug does not map to an existing article
