One of the eight trigrams by exactly one identifier: binary (e.g. 010), english (e.g. Fire), chinese (pinyin, e.g. Li), symbolic (e.g. Radiance), or element (Chinese character, e.g. 火). This returns a single trigram; list_trigrams returns all eight. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms.
