Is this Japanese SSW support organization in ISA's list? Hosted; tracks list changes. Relay only.
Scored across 4 tools
The two domain tools (support_org_lookup vs support_org_changes) are clearly separated: one is a point/attribute query, the other a time-based diff feed. The two meta tools (catalog, get_receipt) are also distinct, though the boundary between a paid-call receipt retrieval and a general catalog listing could momentarily blur for a new agent.
The domain tools follow a clean, namespaced entity_action pattern (support_org_lookup, support_org_changes), but the meta tools break the convention: 'catalog' is a bare noun while 'get_receipt' is verb_noun. Readable overall, but three different conventions are mixed in a four-tool set.
Four tools is lean but each earns its place: two domain queries, one discovery tool and one payment-recovery utility. For a narrow, read-only directory service this scope is reasonable, though it sits at the thin end of the range.
Lookup covers registration number, name fragment, prefecture and language, and changes covers history since a date, so the core query workflows exist. However, there is no way to enumerate or page through the full current list (no list-all or count), which is a notable gap for a registry-browsing service.

Which registered support organizations were added to, changed in, dropped from or returned to Japan's official ISA list since a date? From this service's own record of list versions (ISA publishes only the current list).

Free window: last 30 days (see history_window).
Inputs: since (required), limit, prefecture, change_type. Returns: query, terms, changes, coverage, +9 more
