TTB Open Data
TTB's open data surface is a set of static, anonymously downloadable files rather than a request/response API. Production and operations reports for beer, wine, distilled spirits and tobacco are published as JSON and CSV under /system/files//, and two processing-time feeds are refreshed daily as XML and CSV under /images/foia/. There is no OpenAPI, no query API, no API key and no rate limit; format is selected by choosing a different file, not by content negotiation. Dataset metadata is published in Project Open Data / DCAT-US 1.1 form inside the Department of the Treasury catalog, where 34 records carry publisher.name "TTB".
