# Gkmex API authentication

The public Gkmex crane inventory API and MCP tools require no authentication. They are read-only and expose the same commercial listing fields shown on public Gkmex pages.

No credentials, account, cookie, bearer token, or sign-up is required. Enquiries, condition-report requests, transport questions, financing questions, and quotations continue through the public Gkmex contact page or info@gkmex.com.

## Verify zero-auth access

Run this request exactly as shown, without an Authorization header, account, cookie or API key:

```bash
curl --fail --show-error https://gkmex.com/api/health
```

The live production endpoint returns HTTP 200 and a JSON status document. You can then call `GET https://gkmex.com/api/v1/cranes` or connect to `https://gkmex.com/mcp`; both are safe, read-only ways to evaluate the current public integration, so no separate sandbox is required.
