Federal Administrative Procedure Sourcebook API
The Federal Administrative Procedure Sourcebook is ACUS's reference wiki covering the core statutes of U.S. federal administrative procedure — the Administrative Procedure Act, FOIA, the Privacy Act, the Government in the Sunshine Act, FACA, the Negotiated Rulemaking Act, the Regulatory Flexibility Act, the Paperwork Reduction Act, the Equal Access to Justice Act and more. It runs on MediaWiki 1.43.0 and exposes both the MediaWiki Action API at /api.php and the MediaWiki REST API v1 at /rest.php/v1. Both answer anonymously with no API key, account or quota. This is the only programmatically callable interface ACUS operates. Note that every acus.gov host returns HTTP 403 to non-browser user agents, so a client must send a browser-like User-Agent header.
