InternetData

What is inside one database before you fetch it: the columns in each published format with their types, a few sample rows, the row count, the build date and the file sizes. Use this to answer questions about what a database contains without downloading it - the files reach several GB - and to budget a transfer before starting one.

database_metadata

The published digests for one database file, for verifying a copy you already hold or deciding whether a build has changed since you last fetched it. It is licensed like the download itself, so a database this key cannot download is refused here too. Looking up a checksum is not a download and does not appear in `list_downloads`.

database_checksum

The IP database catalog as this API key's organization may see it, one entry per database FAMILY, with `standing` saying where their license stands: `licensed` if the family is theirs today, `expired` if the term has ended, `unlicensed` if it is published but has never been bought. Each entry has a `base` id, which is what a license names, and a `versions` array whose `id` is what the other tools take - pass `versions[].id` (`bogon_ip_v1`), never the `base` (`bogon_ip`). Ask again rather than holding on to this: it is answered per key and is not the same for everyone.

list_databases

This organization's own recent download attempts, newest first, REFUSALS INCLUDED - a denial carries the `outcome` and `http_status` that answer "it stopped working", which nothing else here can. Use it to explain a failing fetch, to confirm a transfer ran, or to check whether a request was theirs. This is a bounded WINDOW of at most 200 rows, so a database missing from the answer means it is not in this window - never that it was never downloaded.
