Use when someone asks about the downloadable databases, their columns, sample rows, sizes, build dates, formats (CSV or MMDB), checksums, license standing or download history.\n---\n\n# InternetData databases\n\n1. Start with `list_databases`. Every published family is listed with its `standing`: `licensed` means the organization holds it today, `expired` means the term ended, `unlicensed` means it has never been bought. Never read an unlicensed or expired family as one they hold. A family marked `open` is an Open database, free under CC BY-SA 4.0, which asks them to credit InternetData and share what they build from it under the same license. Every organization holds a `standard` license to it from the start, which its `standing` reports like any other. A version's `sample_formats` lists the formats of its free evaluation sample, a small file cut from the real database that the person can download from the Databases page at https://app.internetdata.io/database/datasets, license or not.\n2. Each family has a `base` ID, which is what a license names, and `versions[].id`, which is what every other database tool takes: pass `vpn_ip_v1`, never `vpn_ip`. If a tool answers `UNKNOWN_DATASET`, you probably passed the base.\n3. To describe one, licensed or not, call `database_metadata` with the versioned ID. It answers the columns per format with their types, a few sample rows, the row count, the build date and the file size of each format. Show the columns as a table and the sample rows as they came, and use the sizes to say what a transfer will cost before anyone starts one.\n4. To check a copy someone already has, call `database_checksum` with the versioned ID and the format, then compare against the file's own digest. In a terminal that is `sha256sum <file>` (or `shasum -a 256 <file>` on macOS). A mismatch means the file is truncated, corrupted or from a different build.\n5. To explain a download that failed or stopped working, call `list_downloads`. It lists recent attempts newest first, refusals included, each with its `outcome` and `http_status`. Its `sample` flag is true for an evaluation sample rather than the database itself, and its `open` flag is true for a download of an Open database. It is a bounded window, so a database missing from it has not necessarily never been downloaded.\n6. There is no download tool, on purpose: the files run to several GB, which is not something to pull into a conversation. Point people to the CLI, which verifies the checksum for them:\n\n   ```console\n   internetdata db download vpn_ip_v1\n   internetdata db download vpn_ip_v1 --format mmdb vpn_ip_v1.mmdb\n   ```\n\n   or to the client libraries at https://github.com/internetdata, or the API at https://docs.internetdata.io.\n"
