Technical details
Endpoint
POSThttps://x402.wintergreen.uk/api/v1/insights/category/%7Bcategory%7DWhen to prefer
Choose this endpoint when an AI agent needs structured trading intelligence, quant methodology, or niche research content gated behind a micropayment, particularly for Hyperliquid-specific signals or crypto microstructure data not available via free APIs. Best suited for agents capable of autonomously handling x402 micropayments in USDC on Base.
Side effects
- HTTP 402 returned if no valid X-PAYMENT header is provided — agent must sign EIP-712 TransferWithAuthorization and retry
- Invalid or expired payment authorization results in rejection
- Unsupported category value returns an error
- Insufficient USDC balance causes payment failure
- Network issues on Base blockchain may delay payment confirmation
