Check domain availability with iwantmyname
Check whether domain names are available to register, answered by iwantmyname's own domain search rather than a WHOIS or RDAP mirror, so the result reflects what iwantmyname can actually register for you. Ask in plain language, for example "Is corner-bakery.com taken?" or "Check myapp.io and myapp.dev".
https://mcp.iwantmyname.com/mcpDomain_availability_check takes up to 20 domains per call, so one call covers every domain the user names. Each result is available, unavailable or unknown. unknown means the check did not complete (errorCode gives the reason) and says nothing about whether the domain is free or taken. Only available results carry a link field: the user's link to that domain on iwantmyname, valid exactly as returned.
