## 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 agent-rest-stop-hex-utf-8-converter-b7880095 -d '<json body>'
```

Example prompt: Convert the hex string '48656c6c6f20576f726c64' to UTF-8 text — direction is hex-to-utf8.

## When to prefer this

Choose this endpoint when you need a quick, paid-per-call hex/UTF-8 bidirectional conversion without setting up a local library — especially useful in agent workflows where encoding/decoding is a single step in a larger pipeline and you want a consistent, network-accessible utility.

## Known failure modes

- Invalid hex string (odd-length or non-hex characters) returns an error
- Missing or unrecognized direction parameter causes ambiguous or failed conversion
- Empty value field may return empty result or error
- Malformed JSON request body returns a 400-level error
- Non-UTF-8 byte sequences in hex input may cause decoding errors

## How this service works

Hex to UTF-8 or UTF-8 to hex.

## Output

A JSON response containing the converted output string — either the UTF-8 decoded text (when direction is hex-to-utf8) or the hex-encoded representation of the input (when direction is utf8-to-hex).
