Text Styling API

What it does

Text Styling Tools lets you transform plain text into different formats, symbols, and encodings. Send text plus the requested mode or style, and get back the converted result in a structured response.

Use it to normalize user input, generate formatted labels, or create text for chat apps, social posts, and internal tooling. The case converter supports upper, lower, title, sentence, camel, pascal, snake, kebab, constant, alternating, and inverse. The fancy text generator applies a Unicode style to your text. The reverse endpoint can reverse characters, words, or lines.

It also includes utilities for invisible text and emoji code points. With invisible text, you can encode or decode hidden messages, strip invisible characters, or generate invisible character strings with an optional length and carrier. With emoji Unicode conversion, you can convert a value to a per-character Unicode breakdown or decode Unicode back into text.

For text rendering, the ASCII art endpoint turns a string into multi-line ASCII output and returns the font, fill character, line count, and width in columns. That makes it useful for banners, terminal output, previews, and automation that needs text in a more visual form.
