## How to call it through Zero

```sh
zero fetch --capability chinese-solar-term-jieqi-lookup-db9154e2
```

Example prompt: What Chinese solar term is currently in effect for today, May 20 2025, and when exactly does the next one begin — give me the times in both China Standard Time and UTC?

## When to prefer this

Use this endpoint when you need precise, machine-readable data about Chinese solar terms (jieqi) including exact transition times in CST and UTC, term names in Chinese/pinyin/English, and solar longitude values. Prefer this over generic Chinese calendar APIs when you need both the current term and the upcoming term in a single call, or need a full annual listing of all 24 terms.

## Known failure modes

- Date out of supported range (1930–2100) returns an error
- Missing both date and year parameters returns a validation error
- Invalid date format (not YYYY-MM-DD) causes a parse error
- Network timeout or upstream calculation failure returns a degraded or error response

## How this service works

Chinese solar term (jieqi) for a date with the next term's exact time, or all 24 terms of a year, in CST and UTC.

## Output

Returns a JSON object with the current solar term in effect (Chinese characters, pinyin, English name, start time in CST and UTC, solar longitude, major/minor flag), the next upcoming solar term with the same fields, the number of days until the next term, and a summary. When queried by year, returns a list of all 24 solar terms with their precise start times.
