## 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 shell-script-review-via-bash-n-and-shellcheck-d0e985a6 -d '<json body>'
```

Example prompt: Can you run a full shellcheck and bash syntax check on this script and show me any issues with line numbers and SC codes?

## When to prefer this

Choose this endpoint when you need deterministic, LLM-free shell script linting that combines both bash -n syntax validation and ShellCheck static analysis in a single call, returning structured findings with line numbers and official SC codes suitable for automated CI pipelines or agent-driven code review workflows.

## Known failure modes

- Empty or missing script body returns an error
- Non-shell content submitted may produce misleading results
- Network timeout for very large scripts
- Payment failure returns HTTP 402 before analysis runs
- Malformed JSON body returns 400 Bad Request
