Domain Checker Brazil (.com.br, .com, .net)

FREE domain availability checker -- real-time RDAP lookups, no API key needed.

Check if your desired domain name is available across .com.br, .com, and .net extensions instantly using the official RDAP protocol.

What is RDAP?

RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. It provides structured, reliable domain registration data directly from official registries:

• .com / .net -- Verisign RDAP servers
• .com.br -- Registro.br RDAP server

Use Cases

• Startup naming -- Check if your brand name is available across Brazilian and international domains
• Brand protection -- Monitor domain registrations for your brand
• Bulk domain check -- Verify availability of up to 50 domains per run
• Domain investing -- Quickly scan for available domain names

Input

Field	Type	Default	Description
domains	string[]	-	List of domain names to check (max 50)
domain	string	-	Single domain name to check
checkCom	boolean	true	Check .com availability
checkComBr	boolean	true	Check .com.br availability
checkNet	boolean	false	Check .net availability
delayMs	integer	200	Delay between domain checks (ms)

You can provide just the base name (e.g., google) or a full domain (e.g., google.com.br) -- the actor will extract the base name automatically.

Output

Each result contains:

{
    "domain": "example",
    "com": true,
    "com_br": false,
    "net": true,
    "checkedAt": "2025-01-15T10:30:00.000Z"
}

• true = domain is available (not registered)
• false = domain is registered (taken)
• null = error or timeout during check

Limits

• Maximum 50 domains per run
• 8-second timeout per RDAP request
• Configurable delay between domains to respect rate limits

Cost

This actor is completely FREE to use. RDAP is an open protocol and requires no API keys or subscriptions.

Example

{
    "domains": ["meusite", "minhaempresa", "lojaonline"],
    "checkCom": true,
    "checkComBr": true,
    "checkNet": false
}
