Most api interfaces in the market need to be called for a fee, but some api interfaces can be called for free.

These api interfaces can be called for free. These free api interfaces are usually used to attract traffic, expand business and improve platform visibility.
What can benefit the api interface platform is those api interfaces that need to be charged. The cost of api interfaces has always been a point that enterprises can't ignore when choosing some interfaces. Generally speaking, different api interface platforms have different charging standards. Some api interface platforms will charge according to the number of calls to api interfaces, and will also give some free calls according to whether they are members or not. There are also interface platforms that provide annual or monthly services. After purchasing this service, enterprises can call an api interface for a certain period of time.
Even for the same interface platform, different api interfaces will have different charging standards. This is because the investment in developing these api interfaces is different, that is, the cost of api interfaces may be affected by the cost of developing this api interface. Specifically, this cost may include the amount of data needed by the enterprise or what the specific business needs of the enterprise are, and so on.
