Gartner estimates that by 2023, infrastructure service providers (another name for cloud providers) will generate 65 percent of their revenue from APIs, up from 15 percent in 2018.
The OpenAPI specification is language and platform agnostic and, largely because of this, has been widely adopted by API-driven companies such as Atlassian, MuleSoft, Netflix and PayPal.
Average salary which is being paid to the employee who knows API and can work on it easily is USD 24,662 and increases as the profile in the work function develops.
