Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/searchWhen to prefer
Choose this endpoint when an AI agent needs ready-made, curated prompts or financial market data gated via x402 micropayment, and the agent has USDC payment capability. Particularly useful when building trading or DeFi agents that need pre-built prompt packs without constructing datasets from scratch.
Side effects
- Payment failure or insufficient USDC balance results in 402 Payment Required with no content returned
- Empty or overly broad query string returns no matching results
- Invalid or unrecognized pack identifier returns empty result set or error
- Unspecified response schema means content structure may be inconsistent or undocumented
- Service unavailability results in timeout or 5xx error
