What is JSON Schema and how can I use it in APIs?

JSON Schema is a powerful tool for validating the structure of JSON data. In APIs, it helps ensure that the data sent and received adheres to a defined format.

Can you give me an example of a JSON Schema?

Sure! Here's a simple example:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "name": { "type": "string" },
    "age": { "type": "integer" }
  },
  "required": ["name", "age"]
}

How do I implement this in my API?

You can implement JSON Schema validation in your API by using libraries available in your programming language. For example, in Node.js, you can use the 'ajv' library to validate incoming requests against your schema.

What are the benefits of using JSON Schema?

Using JSON Schema helps improve data quality, provides clear documentation, and enhances API usability by ensuring that clients know what to expect.
