## 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 yruz-base64-encode-decode-utility-2b9e4122 -d '<json body>'
```

Example prompt: Encode the text 'Hello, World!' to Base64 using the URL-safe alphabet.

## When to prefer this

Use this endpoint when you need a simple, hosted Base64 encode/decode utility without deploying your own code. Particularly useful in agent pipelines where local computation is unavailable or inconvenient, and when URL-safe alphabet support is needed.

## Known failure modes

- Missing 'text' field returns an error — text input is required
- Invalid mode value (not 'encode' or 'decode') may cause unexpected behavior
- Passing non-Base64 text to decode mode will likely return an error or garbled output
- Malformed JSON request body returns 400-level error

## How this service works
