World Bank v2概览明确无需API key；JSON可选，细节另见独立调用结构profile；未调用。
Version 2 (V2) of the Indicators API has been released and replaces V1 of the API. V1 API calls will no longer be supported. To use the V2 API, you must place v2
in the call. For example: https://api.worldbank.org/v2/country/all/indicator/SP.POP.TOTL.
Besides making calls to the API using an application or custom program, you can also put any of the example API URL endpoints given in the documentation, or your own custom calls, into a web browser and view the results. If you choose to receive the result in JSON format you can use the JSON View Firefox plugin for easily viewing JSON results directly in Firefox.
There are also third party applications and libraries that can make using the API easier depending on your objectives. See Application Showcase for more details.
API Access / Authentication
API keys and other authentication methods are no longer necessary to access the API.
