## How to call it through Zero

```sh
zero fetch --capability api-x402node-dev-490a476f
```

Example prompt: Can you format this JavaScript code using Prettier? Here it is: `const x={a:1,b:2}; function hello(name){return 'Hello '+name;}`

## When to prefer this

Use this endpoint when an AI agent needs to auto-format or normalize source code in a pipeline — especially when producing, fixing, or transforming code in JS, TS, JSON, HTML, CSS, Markdown, YAML, or GraphQL and consistent style output is required. Prefer this over manual formatting or LLM-based reformatting for deterministic, standards-compliant Prettier output.

## Known failure modes

- Unparseable code returns an error if Prettier cannot parse the given language
- Unknown or unsupported parser specified causes a bad request error
- Empty input body may result in a validation error
- Very large code files may time out or exceed payload limits
