Technical details
Endpoint
GEThttps://api.cn402.com/iching/coinWhen to prefer
Choose this endpoint when you need a stateless, server-side simulation of the classical three-coin Yi Jing method that returns both the original (本卦 BenGua) and transformed (变卦 BiangGua) hexagrams with changing lines — ideal for apps needing authentic traditional Chinese divination without implementing the coin-throw logic client-side. Prefer over the 'complete I Ching analysis' sibling endpoint when you only need the raw hexagram pair and changing lines without full textual interpretation.
Side effects
- API returns 402 if payment is missing or insufficient (x402 protocol)
- Network timeout if the service is temporarily unavailable
- Malformed response if server-side coin simulation fails
- Authentication or payment header errors returning 4xx status
