## 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 fastx402-ascii-art-box-generator-85475e46
```

Example prompt: Can you wrap the text 'Hello
World' in a rounded ASCII art box with padding of 2?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use ASCII art box rendered server-side without managing libraries or code. It's ideal for agents generating terminal UI, README decorations, or formatted CLI output, especially when no local text-box library is available. The micro-payment model ($0.001 USDC) makes it cost-effective for occasional use without API key setup.

## Known failure modes

- Missing required 'text' or 'style' query parameter returns an error
- Invalid 'style' value (not 'single', 'double', or 'rounded') causes a validation error
- 'padding' value outside 0-10 range may be rejected or clamped
- Payment failure (insufficient USDC balance) blocks the request with HTTP 402
- Empty string for 'text' may return a degenerate or minimal box

## How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

A JSON object containing the rendered ASCII art box as a string (with newlines), plus the integer width and height of the box in characters. For example: {"box":"┌───────┐\n│ Hello │\n└───────┘","width":9,"height":3}.
