JSON

json is the default data format learners inspect in Brevvie Python + AI — Section 4: APIs, Postman & Calling the Web. The source frames it as close to a Python dict: quoted keys, primitive values, lists, and nested objects.

Role in the source

• API responses are usually returned as JSON
• Postman displays JSON visually
• httpx parses JSON into Python objects with .json()

Why it matters

Reading nested JSON is a practical skill for working with almost any external API.
