"API Economy"
The Core Concept
The API Economy refers to the shift in business models where companies expose their digital services via APIs for others to build upon.
Uber is a classic example: it doesn't build its own maps (it uses Google Maps API) or its own payments (it uses Stripe API). It is a business built by stitching together other APIs. Conversely, companies like Twilio or Stripe exist entirely to sell their API as a product.
Why It Matters
Speed of Innovation: Developers don't have to reinvent the wheel; they just plug in an existing solution.
New Revenue Streams: Companies can monetize their data or functionality by charging for API access.
Ecosystem Lock-in: If everyone builds on your API, you become an indispensable platform.
Key Components
Microservices: Breaking big apps into small, connected API services.
Documentation: The manual that tells developers how to use the API (critical for adoption).
