## 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 nexusapi-base64-encode-a5b25650 -d '<json body>'
```

Example prompt: Encode the string 'Hello, World!' into Base64 format for me.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call Base64 encoding operation without managing API keys or infrastructure. Ideal for AI agent workflows that occasionally need Base64 encoding as a step in a larger pipeline and want a simple HTTP call rather than running local code. Less appropriate if you are encoding large volumes of data where per-call pricing would be expensive.

## Known failure modes

- Empty input string returns an error or empty encoded output
- Malformed JSON body causes a 400 bad request
- Network timeout if the service is unavailable
- Payment failure if USDC balance is insufficient on Base network
- Very large inputs may exceed request size limits

## How this service works

## Output

Returns a Base64-encoded string representation of the provided input text or data, suitable for use in HTTP headers, data URIs, or any protocol requiring Base64-encoded content.
