This is a primer. Jit-API shows practical skills, small examples, and job-ready patterns.
API stands for Application Programming Interface.
An API allows different programs to communicate with each other.
Instead of rebuilding everything yourself, an API lets you ask another system for information or actions.
You at a restaurant:
You = application
Waiter = API
Kitchen = server
You tell the waiter what you want.
The waiter delivers the request.
The kitchen sends back the result.
APIs usually work like:
Request → Processing → Response
Application asks:
"Give me weather data."
API returns:
temperature
city
forecast
conditions
Endpoint
The URL where the request goes.
Request
What you ask for.
Response
The information returned.
JSON
Often used to carry the data.
APIs help applications work together.
payments
maps
weather
chat systems
login systems
social media
AI services
APIs let software borrow capabilities instead of rebuilding them.
The real skills of 2025-2030 are: Can you make systems talk to each other clearly and safely?
APIs are how websites, apps, tools, and AI services exchange work.
Requests, responses, endpoints, authentication, JSON, errors, rate limits, webhooks, and documentation all matter when software has to cooperate.
This is a primer. Jit-API shows the practical skills behind system communication, not just terms copied from a list.

Each card has one lecture and one worksheet. In trial.php, the whole card opens the lecture, and the old buttons are hidden automatically.
