## 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 httpay-base64-encode-api-e8abc44f -d '<json body>'
```

Example prompt: Can you base64 encode this text for me: 'Hello, World! This is my API payload' and also give me the URL-safe version?

## When to prefer this

Choose this endpoint when you need a quick, no-setup Base64 encoding utility without managing API keys or subscriptions — ideal for agents that need one-off encoding operations and can pay $0.001 USDC per call via x402 on Base. Prefer this over self-hosted solutions when avoiding infrastructure overhead matters.

## Known failure modes

- Missing or empty text field in POST body returns error
- Malformed JSON body causes parse error
- Oversized payload may be rejected
- Network timeout on slow connections
- Payment failure via x402 prevents access
