Check whether a subdomain label is free before claiming it. Requires no API key. Returns { label, domain, fqdn, available, reason } where reason is 'available', 'taken', or 'invalid' (with a 'detail' explaining why the label is not usable).
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
| domain | string | no | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
