## 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-unicode-block-art-converter-ab412dfa -d '<json body>'
```

Example prompt: Can you convert this image (attached as base64 PNG) into Unicode block art at 80 characters wide?

## When to prefer this

Choose this endpoint when you specifically need Unicode block art (▀▄█ style characters) output from an image, as opposed to ASCII art or Braille art. It is ideal for terminal displays, README files, or any context where Unicode block characters render correctly. Prefer this over ASCII endpoints when you want higher visual fidelity using block characters rather than punctuation-based ASCII.

## Known failure modes

- Invalid or malformed base64 string returns an error
- Unsupported image format (non-PNG/JPEG/WEBP) may cause processing failure
- Width value of 0 or negative integer may cause unexpected behavior
- Very large images or width values may cause timeout or memory errors
- Missing required 'image' field returns a validation error
- Payment failure via x402 micropayment protocol blocks the request

## How this service works

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

## Output

Returns a JSON object containing a success boolean and a data object with the Unicode block art string (blockArt), along with the output width and height in characters. The blockArt field is a multi-line string of Unicode block characters representing the input image.
