Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (7)

`asn-lookup`read-only	Look up normalized RDAP data (holder, country, status, registration dates) for an autonomous system number.
`bulk-domain-lookup`read-only	Look up normalized RDAP registration data for several domain names in one pooled call. Requires a Pro or Business plan; every domain in the batch counts against the quota.
`domain-lookup`read-only	Look up normalized RDAP registration data (registrar, status, dates, nameservers, contacts) for a domain name.
`entity-lookup`read-only	Look up normalized RDAP data for an RIR entity handle — an organization or contact identifier such as "GOGL" or "ORG-RIEN1-RIPE". Only ARIN, RIPE, APNIC, LACNIC and AFRINIC handles resolve; a domain's registrar or registrant comes from domain-lookup instead.
`ip-lookup`read-only	Look up normalized RDAP allocation data (network range, holder, country, status, geofeed URL) for an IP address or CIDR block.
`nameserver-lookup`read-only	Look up normalized RDAP data (IP addresses, status, sponsoring registrar) for a nameserver hostname.
`tlds`read-only	List the TLDs this API can query, or describe one: which RDAP server answers for it, since when it has been supported, and how often that server fills each field. Metadata, so it never counts against the monthly quota.
