Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 minia2a-base64-encoder-decoder-4fa41c58
```

Example prompt: Can you base64-encode this string for me: 'Hello, World! This is my secret payload' — I need the encoded output to embed in an API request.

## When to prefer this

Use this endpoint when you need a quick, reliable Base64 encode or decode operation accessible via a simple HTTP GET call with x402 micropayment, especially in agentic workflows that already handle x402 payment flows and need a lightweight utility without standing up their own encoding library.

## Known failure modes

- Invalid or malformed input data returns an error response
- Missing required 'input' field causes a 400-style error
- Payment failure or insufficient funds blocks the request via x402 protocol
- Extremely large payloads may be rejected or time out
- Incorrectly formatted Base64 input when decoding may return a decoding error
