Corrections & versions

FACTANKER never silently edits the record. Two mechanisms make every change traceable:

Supersession, not deletion. When an official source revises a value, the old fact is marked superseded_by the new one — both remain permanently addressable, and every fact page shows its history.
Article corrections are labeled. If a published finding contains an error, the article is corrected in place with a dated correction note; the claim’s evidence links are updated in the same edit.

Found an error? Write to [email protected] — corrections of substance are acknowledged on the affected page.

Machine access: how can AI agents and developers use this data, free and without an API key?

Every figure shown here about Corrections & Versions 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.
