## 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 agent-data-tools-base64-decode-1357e77b
```

Example prompt: Can you decode this base64 string for me: 'aGVsbG8gd29ybGQ='? I need the original plain text.

## When to prefer this

Choose this endpoint when you need a simple, pay-per-call Base64 decoding utility without setting up API keys or accounts. Useful for AI agents that occasionally need to decode Base64 values as part of a larger workflow, especially when already using other Agent Data Tools endpoints on the same platform.

## Known failure modes

- Invalid base64 input returns an error or garbled output
- Missing required 'text' query parameter causes a 400-level error
- Padding issues in base64 string may cause decode failure
- Non-UTF8 binary data decoded to text may produce unreadable characters

## How this service works

Decode standard or URL-safe base64 to UTF-8 text. Missing padding is tolerated. Use to read encoded headers, tokens and data URLs.

## Output

A JSON object with a single 'text' field containing the decoded plain-text string that was originally encoded in Base64. Example: {"text": "hello world"}
