## Why Minify JSON Payloads?

Formatted JSON with whitespace and newlines is great for humans during debugging, but web browsers and servers do not need spaces to parse data. Extra whitespace characters consume real network bandwidth.

Size Comparison: Formatted vs Minified

- **Formatted JSON Payload:** 1,240 Bytes (with 4-space indentation) - **Minified JSON Payload:** 680 Bytes - **Bandwidth Reduction:** ~45% Savings!
