## 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 avedaris-base64-decode-95a7453a -d '<json body>'
```

Example prompt: Can you decode this base64 string for me: aGVsbG8gd29ybGQ=?

## When to prefer this

Use this endpoint when you need a simple, reliable, pay-per-call Base64 decode without setting up your own infrastructure, especially inside an autonomous agent pipeline that already uses x402 micropayments for other AveDaris utility endpoints.

## Known failure modes

- Invalid or malformed base64 input returns an error
- Input string shorter than minLength of 1 is rejected
- Input exceeding maxLength of 200,000 characters is rejected
- Non-base64 characters in input may cause decoding failure

## How this service works

Decode bounded Base64 into UTF-8 text with validation.

## Output

A JSON object containing a 'result' field with a 'text' property holding the decoded plaintext string corresponding to the input Base64 value.
