What is an API? Explained in Plain Nepali (and English)

Have you ever wondered how your phone apps talk to each other? How does your food delivery app know your location using Google Maps, or how does your bank app send money instantly? The answer lies in something called an API.

This blog by Codeed Labs is here to explain what an API is in Plain English and Nepali, so even if you’re new to tech, you’ll understand it clearly.

What is an API?

Simple English Definition

An API (Application Programming Interface) is a set of rules that allows one software application to communicate with another. Think of it as a messenger that carries requests and delivers responses between two systems.

Simple Nepali Definition (साधारण नेपालीमा व्याख्या)

API भनेको एउटा बीचवाला हो जसले एउटा सफ्टवेयरलाई अर्को सफ्टवेयरसँग कुरा गर्न सजिलो बनाइदिन्छ। उदाहरणका लागि, तपाईँले मोबाइलबाट खाना अर्डर गर्दा, त्यो एपले रेस्टुरेन्टसँग सिधै कुरा गर्दैन, API बाटै कुरा गर्छ।

Breaking Down the Term “API”

• Application – The software you’re using (like an app or website).
• Programming – The code and logic behind it.
• Interface – The bridge that allows communication.

So, API is literally the bridge between two applications.

How Does an API Work?

The Restaurant Analogy

Imagine you’re at a restaurant. You sit at a table with a menu, but you don’t go into the kitchen yourself. Instead, a waiter (API) takes your order to the kitchen (system) and brings back your food (response).

That’s exactly how APIs work — they act as the middleman.

Everyday Examples of APIs

Mobile Apps and APIs

Your weather app fetches real-time weather updates from servers using APIs.

Social Media and APIs

When you log into a game using your Facebook account, that’s an API at work.

Online Payments and APIs

When you pay via Khalti or eSewa inside a food delivery app, APIs handle the secure transfer of information.

Why Are APIs Important?

Connecting Applications Seamlessly

APIs allow apps to work together smoothly without you noticing.

Saving Time and Effort for Developers

Instead of building everything from scratch, developers use APIs to save months of work.

Powering Modern Technology

From AI tools to self-driving cars, APIs are the backbone.

Types of APIs

• Open APIs (Public APIs): Available to anyone, like Twitter API.
• Internal APIs (Private APIs): Used inside a company.
• Partner APIs: Shared between business partners.
• Composite APIs: Combine multiple APIs into one.

Examples of APIs in Real Life

• Weather Apps: Collect weather data from global servers.
• Google Maps: Lets apps access maps and navigation.
• E-commerce Platforms: Payment gateways like PayPal or eSewa.
• Banking and Payments: Secure transactions between apps and banks.

APIs in Nepali Context

Nepali tech is growing, and APIs are everywhere.

• eSewa / Khalti: APIs connect merchants, banks, and users.
• Food Delivery Apps: Use Google Maps API to track locations.
• Ride-sharing apps: Use payment and location APIs.

How Developers Use APIs

• API Documentation: Guides developers on how to use an API.
• Testing and Integration: Developers test APIs before launching.
• Common API Tools: Postman, Swagger, RapidAPI.

Benefits of Using APIs

• Faster Development
• Scalability for growing apps
• Built-in Security features

Challenges of APIs

• Security Concerns: Hackers may target poorly secured APIs.
• Versioning Issues: New updates can break old systems.
• Dependency on Third-Party APIs: If they fail, your app may fail too.

Future of APIs

• Artificial Intelligence: APIs let apps use AI services.
• IoT (Internet of Things): Smart homes rely on APIs.
• Startups: APIs allow small businesses to scale quickly.

Conclusion

APIs may sound technical, but in reality, they are just the middlemen that make apps and software talk to each other. Whether it’s in Nepal’s digital wallets, global e-commerce, or AI-driven apps, APIs are the invisible force behind the smooth experience.

So, next time you order food online, pay with Khalti, or check Google Maps, remember: an API just made it possible!
