Capabilities

Tools 4

get_registrar

Everything this register holds for one IANA registrar ID: accreditation status, RDAP base URL, and any ICANN breach, suspension or termination notice with the date and the notice PDF — each with its source page and a verbatim quote. Returns a LIST: ten IDs today carry two records because ICANN and IANA spell the registrar's name differently, and both are returned rather than one being chosen.

Discovered
list_enforcement_actions

Which registrars has ICANN acted against? Lists the Contractual Compliance notices in this register — breach, suspension and termination — newest first, with the registrar, the date as ICANN prints it, the notice PDF and a verbatim quote of the notice line. Filter by action type or by date to see recent enforcement.

Discovered
resolve_registrar

Which registrar is this? Search ICANN's accredited-registrar register by registrar name (or part of one, e.g. "GoDaddy", "Tucows", "namecheap") or by IANA registrar ID. Returns the matching registrars with their accreditation status and any ICANN enforcement action, each with the page and verbatim quote it was read from. Use this first when you have a name; use get_registrar when you already have the IANA ID.

Discovered
verify_quote

Is this right? Check a claim about a registrar — its accreditation status, its name, an enforcement date — against the register instead of trusting it. Says whether the claim matches a stored value, appears only in the verbatim source quote, or differs (and then what the register says instead), and returns the source page and quote so the claim can be traced upstream.
