Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/methodology/bundleWhen to prefer
Choose this endpoint when an AI agent or quant developer needs a self-contained, authoritative methodology bundle covering the full lifecycle of crypto strategy development — from backtesting validation to live execution and agent orchestration — and is willing to pay $15 USDC per retrieval. Prefer this over free resources when reproducibility, structured rule sets (kill battery), and agent-ready frameworks are required. Not suitable for real-time signal streaming or live market data lookups.
Side effects
- HTTP 402 returned if payment header is missing or invalid — must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Payment to wrong address or wrong chain (must be USDC on Base eip155:8453) causes payment failure
- Malformed X-PAYMENT header results in rejection
- Service unavailability or upstream content errors return 5xx
- Incorrect format parameter value may result in unexpected response structure
