Endpoint

A specific URL where your API listens for requests, like /api/posts or /api/users.

Detailed Explanation

An endpoint is a specific URL where your API receives requests. Think of endpoints as doors into your backend — each door handles specific operations. A /users endpoint returns user data; a /posts endpoint returns posts.

Each endpoint handles specific HTTP methods: GET (read), POST (create), PUT (update), DELETE (remove). Endpoints are routes for your API. They process payloads, validate authentication via tokens, return JSON responses with status codes, and connect to databases.

In the Network Tab of DevTools, you can see every request to every endpoint — including the Status Code, response body, and headers. Loaders call GET endpoints to fetch data, actions call POST/PUT/DELETE endpoints to mutate data. Edge Functions are deployed as endpoints. REST APIs are collections of endpoints. Webhooks send data to endpoints automatically. Middleware processes requests before they reach endpoints. Claude Code helps design and implement endpoint logic.
