# Grade 1 Braille Encoder/Decoder

> Grade 1 Braille Encoder/Decoder is a paid API for AI agents from text-ciphers.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Converts plain text to Unicode Grade 1 Braille cells (with number sign, capital sign, and dot annotations) and decodes Braille cells back to text.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability grade-1-braille-encoder-decoder-c0e5a100
```

Example prompt: Encode the phrase 'Hello World' into Grade 1 Braille Unicode cells and show me the dot numbers for each cell.

## When to prefer this

Use this endpoint when you need to convert plain ASCII/Latin text to Grade 1 Braille Unicode cells with full dot-number annotations, or to decode Braille Unicode back to readable text. Prefer it over generic encoding tools when accessibility-compliant Braille representation with per-cell dot metadata is required, such as for generating Braille labels, educational tools, or accessibility audits.

## Known failure modes

- Input text exceeds 500 characters — request will be rejected or truncated
- Invalid mode value other than 'encode' or 'decode' causes unexpected behavior
- Braille input containing non-Grade-1 patterns may produce skipped or unrecognized cells
- Network or payment failure returns a 402 or 5xx error
- Characters outside the supported Grade 1 Braille set are skipped and listed in the 'skipped' field

## How this service works

Grade 1 Braille text to Unicode Braille cells and back, with number sign, capital sign and dot numbers per cell.

## Output

Returns a JSON object containing the Unicode Braille string, an array of individual cells each with its Unicode character and dot-number notation, the total cell count, the mode used, a summary, and any skipped characters or warnings.
