Example prompt: Can you convert the text 'Hello World! 123' into Unicode Braille characters using Grade 1 uncontracted Braille?

## When to prefer this

Choose this endpoint when you need a deterministic, CPU-side conversion between plain text and Unicode Braille (Grade 1 / uncontracted). Ideal for accessibility tooling, generating Braille-encoded content, or decoding Braille Unicode strings back to human-readable text without any AI inference or ambiguity.

## Known failure modes

- Input text contains unsupported characters not in Grade 1 Braille mapping — may return partial result or error
- Input is empty string — likely returns empty output or validation error
- decode flag set to true but input is not valid Braille Unicode — may return garbled output or error
- Request body malformed or missing required 'text' field — returns 400 or similar error

## How this service works

Convert text to Unicode Braille characters (Grade 1 / uncontracted) or decode Braille back to text. Supports letters, digits, and common punctuation. Deterministic, pure CPU.

## Output

Returns the input text encoded as Unicode Braille characters (or decoded plain text if decode mode is enabled). The output is deterministic and CPU-based, covering letters, digits, and common punctuation.
