Some Websites for hosting and fetching JSON

There are several ways to host JSON data for free and here are the ones which are commonly used:

1. GitHub: You can create a GitHub repository and push your JSON data to it. You can then access the data using the GitHub API.

2. Firebase: Firebase offers a free plan that allows you to store and retrieve JSON data. You can access the data using the Firebase Realtime Database API.

3. JSONbin: JSONbin is a free service that allows you to store and retrieve JSON data. You can access the data using the JSONbin API.

4. Myjson: Myjson is a free and simple service for storing JSON data. You can create, read, update and delete JSON data with simple HTTP requests and easily share it with others.

5. Once you have hosted your JSON data, you can fetch it by making an HTTP request to the URL where it is hosted. If you are using an API, you will need to read the documentation for that API to learn how to make requests to it.

In general, you will need to use a programming language like Python, JavaScript, or Java to fetch the JSON data, as it can't be fetched by simply visiting the URL, you will need to make a GET request to that URL to fetch the data.

You can use the libraries like axios, fetch, request etc in javascript or python to fetch the json from the url.
