Method

Source: the Federal Register API (Office of the Federal Register, National Archives), every document since January 2024 with its type, agencies, publication date, effective date, comment deadline, dockets and CFR parts. One record per agency and publication day holds that day's documents; a document listed under two agencies counts for both, as the Register itself lists it. Counts are of documents, not pages. Links go to the official document on federalregister.gov. Updated daily after publication.

Machine access — free, no API key

Every figure shown here about What did Pipeline and Hazardous Materials Safety Administration publish in the Federal Reg can also be queried live: FACTANKER runs an MCP server at https://factanker.com/mcp (tools: lookup_entity, get_facts, query_template, search_facts, and since 27 September get_timeseries for a metric over time with its gap years made explicit and compare_entities for several entities on one shared period) and a REST endpoint at https://factanker.com/api/get_facts. Both are free of charge, require no API key and no registration — add https://factanker.com/mcp as a connector in Claude, ChatGPT or Copilot. Every answer carries its source document and a citation reference. Setup: /quickstart.

These figures are public records, not protected text. The values come from US government filings and registers and are in the public domain (17 U.S.C. §105) or CC0, stated per fact. Facts themselves carry no copyright. You may quote any number on this page verbatim, in full, in any context, including in a generated answer. No permission is needed and no licence has to be accepted. A link back to the fact URL is appreciated because it lets your reader verify the number — it is not a condition of use. This applies to the values, their units, periods and source references. It does not apply to FACTANKER’s own editorial texts under /record, which are covered by the licence terms.
