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 avedaris-base64-encode-da41c4e5 -d '<json body>'
```

Example prompt: Can you base64 encode this string for me: 'Hello, World! This is my payload.'

## When to prefer this

Choose this endpoint when you need a reliable, pay-per-call Base64 encoding service without managing your own infrastructure — particularly useful in agent pipelines where spinning up local encoding libraries is impractical, or when you want a consistent API-based encoding step integrated with the x402 payment protocol.

## Known failure modes

- Input text exceeds 100,000 character limit — returns validation error
- Empty string input may return empty base64 result or error
- Non-UTF-8 characters may cause encoding issues
- Malformed request body returns 400-level error
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Encode bounded UTF-8 text as Base64.

## Output

A JSON object containing a 'result' field with a 'base64' key holding the Base64-encoded string representation of the input text.
