## 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-11fb5302
```

Example prompt: Can you check if 'Luminary' is available as a startup name — I want to know if the .com, .io, and .ai domains are free, plus whether the Twitter handle, GitHub org, npm package, and PyPI package are taken?

## When to prefer this

Use this endpoint when you need a one-shot multi-platform availability check for a startup or product name, covering both domain registrars and developer/social handles simultaneously, rather than querying each registry separately.

## Known failure modes

- Invalid or missing company_name parameter returns a 400-level error
- External registry timeouts may cause partial results for some platforms
- Rate limiting from downstream services (Twitter, GitHub, npm, PyPI) may reduce freshness
- Very long or special-character names may return unexpected results

## How this service works

Check domain and handle availability for a startup name. Checks .com/.io/.ai/.co/.dev domains, Twitter, GitHub, npm, PyPI.

## Output

Returns availability status for .com, .io, .ai, .co, and .dev domains, plus Twitter handle, GitHub username, npm package name, and PyPI package name — all keyed to the queried company name or keyword.
