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-unicode-block-art-converter-f0a8659e -d '<json body>'
```

Example prompt: Convert this image to Unicode block art with an output width of 80 characters — here's the base64-encoded PNG: [base64data]

## When to prefer this

Choose this endpoint when you need to render an image as Unicode block art specifically (using ▀▄█ block characters) rather than ASCII or Braille art. Ideal for terminal display, chat interfaces, or any context where Unicode characters are supported and you want a compact, character-based visual representation of an image.

## Known failure modes

- Invalid or missing base64 image data — returns error or success:false
- Unsupported image format (not PNG, JPEG, or WEBP) — returns processing error
- Malformed base64 encoding — returns parse error
- Payment not included or insufficient — returns HTTP 402 requiring x402 micropayment
- Width value out of acceptable range — may return validation error
- Image too large or corrupted — may return processing failure

## 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 with a `blockArt` string containing the Unicode block art representation of the image, plus the output dimensions (width and height in characters). The `success` boolean indicates whether the conversion succeeded.
