`check_availability`

Pack: domains · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/check_availability for the schema, then POST the same URL with its arguments for the data.

Check whether a name is available to register across MULTIPLE TLDs at once — the domain-hunting tool. Pass a base name (“acme”) and get .com/.io/.ai/.co/.net/.org/.app/.dev checked in one call (or pass your own tlds list). For each: available true/false (+ expiration if taken). Use for “is X available”, “find an open domain for my project”, “which TLDs is X free on”. Single-domain detail is domain_status; this is the bulk/brainstorm version.

Parameters

Name	Type	Required	Description
`name`	string	yes	Base name to check, e.g. “acme” (a full “acme.com” is also accepted — the label before the first dot is used).
`tlds`	array	no	TLDs to check (without the dot), e.g. [“com”,“io”,“ai”]. Default: com, io, ai, co, net, org, app, dev. Max 15.
`items`	string	no
