Output
The agent receives the content payload associated with the requested slug — which may be a detailed trading signal report, quantitative methodology document, crypto microstructure observation set, power market analysis, or other intelligence product. The response schema is open-ended, so content format varies by slug. A 402 response with payment details is returned first if the USDC authorization header is missing or invalid.
Example use cases
Retrieve Hyperliquid liquidation cluster signals
“Fetch the Hyperliquid liquidation cluster analysis from Wintergreen using the slug 'liquidation-clusters' — go ahead and handle the micropayment on Base.”
Access Kelly sizing risk management guide
“Get me the Kelly criterion sizing methodology guide from Wintergreen — the slug should be 'kelly-sizing-risk-management' — and pay the fee with USDC on Base.”
Pull ERCOT power market field guide
“I need the ERCOT merit-order and duck curve analysis content from Wintergreen, slug 'ercot-field-guide', with the x402 payment handled automatically.”
Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/pm/market-oddsWhen to prefer
Choose this endpoint when an AI agent needs on-demand access to specialized crypto trading intelligence, quantitative methodology, or niche market content gated behind a per-call USDC micropayment. It is ideal for agents with x402-capable payment infrastructure on Base that need to fetch specific content by slug without a subscription. Prefer this over subscription APIs when call volume is low or content needs are ad hoc.
Side effects
- Missing or invalid slug returns an error or empty response
- Missing X-PAYMENT header triggers HTTP 402 with payment instructions
- Insufficient USDC balance or invalid EIP-712 signature causes payment rejection
- Unknown slug with no matching content returns empty or 404-style response
- Base network congestion may delay payment confirmation
- Stale or replayed payment authorization rejected by facilitator
