How It Works
JSON
JavaScript Object Notation: a plain-text format for structured data, written as labeled fields in curly braces — {"name": "Ada", "age": 36}. It is the most common way software systems, including AI APIs, send requests and answers to each other.
Origin
Specified and popularized by Douglas Crockford in the early 2000s; he has said he discovered rather than invented it, since it is a subset of JavaScript. Standardized as ECMA-404 and RFC 8259.
