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 glyphforge-braille-art-converter-a1650a43 -d '<json body>'
```

Example prompt: Convert this image to braille art at 80 characters wide with a brightness threshold of 128 — here's the base64-encoded PNG: [base64data].

## When to prefer this

Choose this endpoint when you specifically need Braille-style Unicode dot-matrix text art from an image, rather than ASCII or block art. It is ideal for creative applications, artistic renderings, or accessibility-themed outputs where Braille character aesthetics are desired. Use when you need fine-grained control over output width and dot threshold.

## Known failure modes

- Missing or invalid base64 image data returns an error response
- Unsupported image format (non-PNG/JPEG/WEBP) may cause decoding failure
- Payment failure via x402 micropayment results in 402 response before processing
- Width or threshold values out of range may produce unexpected output or errors
- Very large images may time out or produce oversized responses

## How this service works

Convert images to ASCII, Braille, Unicode block art, and more. Paid API with x402 micropayments on Base.

## Output

A JSON object containing a `braille` string of Unicode Braille characters representing the image, along with the output `width` and `height` dimensions in braille character units, and a `success` boolean flag.
