Same I'm also not able to get clear idea

In the tech development world, APIs are used to call certain features or services offered by API creators (often giant tech companies such as Google) for use in their products. This is because one often needs easy access to specific features or is unable to create them independently or to the same quality. As a result, they pay these creators to access their API service. The number one example is Google Maps API, which has become a monopoly. Many apps rely on Google Maps for precise location services, which are crucial for ride-hailing, food delivery, and tourism. Some big names dependent on it include Amazon, Uber, Zomato, Swiggy, Blinkit, Airbnb, Snapchat, Starbucks, and over 8,000 other companies. Google Maps initially started as a free service but moved to a paid model as demand grew. It is now expensive, especially for Indian developers, and no new startup can afford such APIs. We plan to build these APIs and initially offer them for free, generating revenue from our own apps created from those APIs—such as a competitor for BookMyShow that uses interactive maps to sell event tickets. Nowadays, every startup is using these APIs rather than building anything on its own, leading to a decline in innovation. Our aim is to make India a hub for providing these APIs globally and to help support startups, solo developers, and innovators. Most startups and devs cannot afford these APIs and it takes a lot of effort and time to build them. So we do the work for them, intially providing it for free and then charging at very affordable rates. And at initial phases generating revenue from the apps created using those APIs and our own also.
