## 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 signaldesk-ai-base64-decode-3c4c9662 -d '<json body>'
```

Example prompt: Can you decode this Base64 string for me: SGVsbG8sIFdvcmxkIQ== — I need to see what the original text says.

## When to prefer this

Use this endpoint when you need a quick, paid, reliable Base64 decoding step inside an automated agent workflow, especially when chaining with other SignalDesk AI tools on the same platform. Suitable for lightweight single-string decoding tasks where consistency and API availability matter more than running local decode logic.

## Known failure modes

- Invalid Base64 input (non-Base64 characters) may return an error or garbled output
- Input exceeding 4096 characters will be rejected
- Empty string input may return empty decoded output
- Padded vs unpadded Base64 variants may cause parsing issues

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object with a 'decoded' field containing the original plaintext string recovered from the Base64-encoded input, e.g. {"decoded": "Hello"}.
