A\nclient has to linear-scan (or pre-index) this list; there is no `/dns.json?tld=com`\nquery form. 592 entries at the 2026-09-30 publication. Sample lookups pulled\nout of the live body:\n\n| TLD | Base URL in the file |\n|---|---|\n| `com` | `https://rdap.verisign.com/com/v1/` |\n| (no `org` seen at top -- PIR entry is `[\"org\"]` further down, same shape) | `https://rdap.publicinterestregistry.org/rdap/` |\n| `uk` | `https://rdap.nominet.uk/uk/` |\n\n**`de` does not appear anywhere in this file** -- confirmed by scanning all\n592 entries for `[\"de\"]`; none exists. See the companion DENIC record: DENIC\nruns a real RDAP server anyway, just not one IANA's bootstrap file points to,\nso any client that trusts only this file concludes (wrongly) that `.de` has\nno RDAP service at all.\n\nSome base URLs are plain `http://` (e.g. the `kg` entry above), not `https://`\n-- a client that upgrades-to-TLS by default should still check, not assume.\n\nThe `services` array is unsorted by TLD (`kg`, `mg`, the punycode form of a\nChinese ccTLD, `tw`, `na` appear consecutively in that order near the top of\nthe live file) -- a client cannot binary-search it and has to build its own\nindex (dict keyed by TLD) to make repeated lookups cheap, which is presumably\nwhy every real client (including `rdap.org`) caches a parsed copy rather than\nre-fetching and re-scanning per query.
