Endpoint
GEThttps://x402donghang.duckdns.org/x402/v1/single-briefWhen to prefer
Choose this endpoint when you need a fast, structured, per-call AI trading brief for a specific crypto token without a subscription, and want to pay per use in USDC. It is ideal for agents that need a concise bias + thesis + actions summary rather than raw price data or charting. Prefer it over generic LLM calls when you want a pre-structured financial brief schema with confidence scoring and invalidation levels baked in.

- Missing required 'symbol' field returns validation error
- Payment not attached or insufficient USDC triggers 402 Payment Required
- Invalid locale value outside 'en'/'zh' enum causes schema rejection
- Context field exceeding 6000 characters is rejected
- Symbol not recognized may produce low-confidence or generic output
