What it is
An API is a contract: send a request in a specific format, get a predictable response back. It is how apps share data and trigger actions.
Why it matters
- Decouples frontends from backends
- Lets tools and services plug into each other
- Makes automation and AI integrations possible
Friendly habits
- Use clear versioning and consistent responses
- Return helpful errors when something goes wrong
- Rate-limit and secure keys from the start
