Examples of code samples for common class API calls in life: Postcode query, today's top news query, area code query, etc.

The following sample code applies to the API under the Www.apishop.net Web site, and you need to request the appropriate API service before invoking the code sample using the interface mentioned in this article.

1. Postcode inquiry: Through the postcode inquires the place name, through the place name inquires the ZIP code
2. Today's top news inquiries: To provide the latest and most timely news information, including headlines, news, finance, sports, entertainment, military, education, science and technology, NBA, stock, constellation, women, health, childcare and other channels, 20 minutes update; Due to the large amount of data, if the request time-out, please request more.
3. Area code query: Area code query (search area code by place name, check place name by area code)
4. Simplified and traditional conversion: simple and traditional conversion
5. Jokes Daquan: The latest and most timely joke jokes
6. Zhou Gong solution dream: Zhou Gong Solution Dream Encyclopedia, Zhou Gong Solution Dream Query, free Zhou Gong dream
7. Coodination query: Coodination time, origin, customs and health
8. Standard Weight calculator: BMI (Body Mass Index, BMI), calculates whether your body is standard by height and weight
9. Express Logistics query: Automatic identification of courier companies, providing including Shentong, Shun Fung, Yuantong, Yun Tatsu, in-Pass, Huitong, EMS, Daily, Guo Tong, darbond, home emergency delivery, such as hundreds of express logistics company tracking interface
10. Exchange rate Query: Provide exchange rate conversion, a single currency corresponding to the popular currency exchange rate, including RMB, USD, EUR, GBP and other more than 100 currencies real-time exchange rate query.

**api Shop (apishop.net) offers up to 50 common third-party APIs that can be downloaded from GitHub on a collection of code samples: https://github.com/apishop/all-apis**

The above interfaces contain code examples in four languages, such as PHP, Python, C #, and Java , to query the exchange rate API for a given currency, for example:
