## 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 filename-sanitizer-237b3cef
```

Example prompt: Can you sanitize this text so it's safe to use as a filename on any operating system: "Report: Q1/2024 Results (Final*Draft)?"

## When to prefer this

Use this endpoint when you need a quick, reliable, server-side filename sanitization without implementing your own character-replacement logic. Ideal for agents that accept user-generated text as file names or need to store files programmatically across multiple operating systems.

## Known failure modes

- Missing required 'filename' query parameter returns an error
- Extremely long filenames may be truncated or cause unexpected behavior
- Edge cases with only illegal characters may produce an empty or minimal result

## How this service works

Convert arbitrary filename text into a safe cross-platform filename by replacing illegal characters.

## Output

Returns a sanitized version of the input filename string with illegal or unsafe characters replaced, making it safe for use across Windows, macOS, and Linux file systems.
