## How to call it through Zero

```sh
zero fetch --capability api-strale-io-245977f0
```

Example prompt: Can you add Google-style docstrings to this Python function: `def calculate_tax(income, rate): return income * rate`?

## When to prefer this

Use this endpoint when you need automated, style-consistent Python docstrings generated for functions or classes and want to choose between Google, NumPy, or Sphinx documentation formats. Ideal for CI/CD pipelines, code review automation, or IDE plugins that need per-function documentation on demand.

## Known failure modes

- Missing required 'code' query parameter returns error
- Invalid or non-Python code may produce malformed or empty docstrings
- Unsupported style value falls back to default or returns error
- Very long code snippets may hit size limits
- Network timeout for complex multi-class inputs

## How this service works

Add Python docstrings to functions and classes. Supports Google, NumPy, and Sphinx styles.

## Output

Returns generated Python docstring(s) for the submitted code, formatted in the requested style (Google, NumPy, or Sphinx), covering parameters, return values, and descriptions.
