All Subdomains Feed Examples

Worked examples for the All Subdomains feed, every subdomain Deepinfo knows about: one request per file format. The API does not return the data itself but a link to download the current file, with its size (file_size, in bytes), its number of lines (line_count) and when it was last updated (file_update_time).

Every example is a real response from September 24, 2026. download_url is a signed link that is valid for one hour (X-Amz-Expires=3600); its credential and signature are shown as <redacted> on this page. Request the link again when you need the file; the file is compressed (.json.gz, .csv.gz or .zstd.parquet).

The Parquet file is requested with file_format=parquet: the API accepts it and the Feed List names it for every feed, next to CSV and JSON. The reference of file_format lists only csv and json; these examples show that parquet works as well.
