## 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 string-encoding-converter-base64-base64url-hex-6c923218
```

Example prompt: Can you encode the string 'Hello, World!' to base64 for me?

## When to prefer this

Choose this endpoint when you need a quick, hosted, on-demand string encoding without running local code — particularly useful for agents that need to encode values in real-time workflows, construct auth headers, or prepare URL-safe tokens without access to a local runtime environment.

## Known failure modes

- Missing 'input' query parameter returns an error
- Unsupported 'to' encoding type (not base64, base64url, or hex) may return an error or unexpected result
- Very large input strings may result in timeout or truncation
- Network errors or service unavailability return HTTP 5xx

## How this service works

Encode a string. ?to=base64|base64url|hex&input=hello

## Output

Returns the encoded representation of the input string in the requested format (base64, base64url, or hex), suitable for direct use in downstream systems, headers, or data pipelines.
