Technical details
Endpoint
GEThttps://api.cn402.com/geo/cn/provinceWhen to prefer
Use this endpoint when you need structured geographic or demographic data about Chinese provinces, such as capital cities, area, population, or regional classification. Ideal for enriching datasets with China administrative info, building China-focused geographic features, or answering user questions about specific provinces. Prefer over a general web search when structured, reliable, machine-readable province data is needed.
Side effects
- Province name or code not recognized — returns error or empty result
- Ambiguous province name input causing incorrect match
- Non-mainland China regions (e.g. Hong Kong, Macau, Taiwan) may not be included
- Network or payment (x402) authorization failure returns HTTP 402 or 5xx
- Incorrect encoding of Chinese characters in input causing lookup failure
