How this service works
Look up an I Ching hexagram by number or lines, or cast one from a question and date with changing lines.
Output
Returns a structured I Ching reading including: the primary hexagram's number, Chinese name, pinyin, Unicode symbol, upper and lower trigrams (name, nature, Chinese), the six-line pattern, an English name, a summary interpretation, a verdict, and optionally a relating (transformed) hexagram when changing lines are present, plus data source and timestamp.
Example use cases
Career decision I Ching reading
“I'm wondering whether to start my own business — can you cast an I Ching hexagram for the question 'Is now the right time to launch my startup?' using the date 2025-07-15 and tell me what it says including any changing lines?”
Look up specific hexagram by number
“Can you look up I Ching hexagram 42 — Yi, Increase — and give me its Chinese name, pinyin, symbol, upper and lower trigrams, and the line pattern?”
Identify hexagram from a line reading
“I drew six lines in an I Ching reading and got solid, solid, broken, solid, broken, broken from bottom to top — that's 110110 — can you tell me which hexagram that is and what it means?”
Technical details
Endpoint
GEThttps://chinese-culture.x402tookit.com/i-ching?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable I Ching hexagram data — either by direct lookup (number or line pattern) or deterministic casting from a question. Prefer it over generic text-based divination if you need parsed trigram data, symbols, and changing-line analysis. The cast function is deterministic (same question + date always returns the same hexagram), making it suitable for reproducible readings.
Side effects
- Invalid hexagram number (outside 1-64) returns an error
- Ambiguous or conflicting query parameters (e.g. both number and lines provided with mismatch) may return an error or default behavior
- Lines string not exactly 6 characters of 0s and 1s returns a validation error
- Missing required cast text when using cast mode returns an error
- Network timeout or upstream service unavailability
