## 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 api-strale-io-e462a41f
```

Example prompt: Can you check if the username 'aurora' is available across GitHub, Twitter, Instagram, TikTok, LinkedIn, YouTube, and Reddit all at once?

## When to prefer this

Use this endpoint when you need to check a single username string against multiple social platforms simultaneously, particularly for brand creation, product launches, or personal identity setup across the web. Prefer this over manual per-platform checks or scraping when you need fast, structured multi-platform results in one call.

## Known failure modes

- Username parameter missing — returns validation error
- Rate limiting or platform-side unavailability may cause partial results
- Very new or obscure platforms may not be included in the 11-platform sweep
- Username with special characters may behave differently per platform

## How this service works

Check username availability across 7 platforms: GitHub, YouTube, TikTok, Reddit, Pinterest, npm, PyPI.

## Output

Returns availability status for a given username across 11 social platforms, indicating whether each platform's handle is taken or free.
