GET /us/statutes/coverage is the live answer and this page is not.
It reports every jurisdiction, every corpus and every section count at the moment you call it, it is free, and it needs no authentication beyond your key.
The human-readable version is Coverage, and what has already shipped is in the Changelog.
Everything below ships through the same pipeline as the current data: official government source, chunked and embedded, citation-linked, on a recurring refresh.
Each lands behind the same corpusType filter, so there is nothing to integrate.
This page is maintained by hand and the corpus is not, so treat it as direction rather than as a manifest. Poll
GET /us/statutes/coverage to detect new corpora, and see Coverage monitoring for a scheduled diff. No date on this page is a commitment.Completing existing coverage
State regulations reached all 52 jurisdictions on 2026-08-27, and state agency guidance is effectively complete at 49. Two gaps remain inside corpora that are otherwise live.
The remaining court-rules jurisdictions either publish no consolidated rules text from a government source, codify their rules into the statute book (already served under
STATE), or restrict automated access by published court policy.
The three missing agency-guidance jurisdictions publish no cleanly scopable insurance-only archive.
Pennsylvania’s Consolidated Statutes are complete; only the older unconsolidated Purdon’s material is outstanding.
Point-in-time and as-applied federal law
The current text of a rule answers what it says today. It does not answer what it said on the date of the conduct, which is the question most compliance disputes actually turn on. The CFR annual editions, 1996 to 2026, are live undercorpusType=CFR_ANNUAL, and the Statutes at Large are live under SESSION_LAW.
These are what is still missing around them.
The LSA is the official month-by-month map from a CFR section to the change that hit it and the Federal Register page that made it.
It is the join key between the
CFR and FEDERAL_REGISTER corpora already in the API, and it answers “what changed this month” directly.
Now that the annual editions are in, the LSA is what turns two adjacent editions into a reason a section changed.
FAR and DFARS class deviations matter because, since the Federal Acquisition Regulation overhaul, agencies have been applying model deviation text that 48 C.F.R. does not yet reflect.
FAR and DFARS are already served inside CFR; the deviations are what a contracting officer is operating under in the meantime.
Federal court rules
The local rules of the 94 district courts, the 13 circuits, and the bankruptcy courts, adopted under 28 U.S.C. 2071 and Federal Rule of Civil Procedure 83.
These modify the national Federal Rules in every district, so the national rules alone are an incomplete picture of what governs a filing.
They are citable in their own form, for example
N.D. Cal. Civ. L.R. 7-2.
This is a large item: roughly 200 separate courts each publishing their own set, mostly as PDFs, with no common schema.
Tax
The Internal Revenue Manual is live underAGENCY_GUIDANCE, as are IRS notices, revenue procedures, revenue rulings and announcements.
Two IRS corpora are not.
Administrative adjudication
corpusType=AGENCY_ADJUDICATION is live and currently serves seven bodies: FTC Part 3 administrative filings, SEC opinions and adjudicatory orders, MSPB, BIA and Attorney General precedent decisions, NLRB Board decisions, DOJ Office of Legal Counsel opinions, and CFPB enforcement actions.
See Federal coverage for the per-body scope limits, which are real and worth reading before you rely on this corpus.
These bodies are not in it yet.
The DOL bodies span an 80+ case-type taxonomy: SOX, AIR21, STAA, ERA, OSH, OFCCP, LCA, black lung and longshore, among others.
On customer demand: the Occupational Safety and Health Review Commission (OSHRC), the Federal Mine Safety and Health Review Commission (FMSHRC), the Federal Energy Regulatory Commission (FERC), Commodity Futures Trading Commission (CFTC) reparations, the US Tax Court, the Armed Services and Civilian Boards of Contract Appeals (ASBCA and CBCA), the EPA Environmental Appeals Board, and the Departmental Appeals Board (DAB) of the Department of Health and Human Services (HHS).
Federal regulatory dockets
Rulemaking dockets and the public comment record behind a rule, sourced from three official, documented government APIs.Agencies not yet covered
No documents from these agencies are in the corpus today.
Agencies that are covered, and were on an earlier version of this list, include the FTC, the SEC, the CFPB, the DOJ Antitrust Division, the DOL Wage and Hour Division, the EEOC, CMS, OFAC and the IRS.
Their per-source detail is in Agency guidance coverage.
Under evaluation
United States Reports, for official star pagination. The text of Supreme Court opinions is available in many places. The bound volumes are the only place the official page numbers live, and a pin cite in the form576 U.S. 644, 681 is what survives into a brief.
This is the one case law item we are weighing, and only for the pagination anchor.
It would not change the position immediately below on general case law and dockets.
Out of scope
Deliberate exclusions, not gaps. If you need one of these, we are not your supplier.GAO
GAO decisions of the Comptroller General on appropriations law and bid protests were previously planned and are now a deliberate no. The obstacle is policy, not transport. GAO disallows every listing inrobots.txt, hard-403s them, publishes a Crawl-delay of 420 seconds, and offers no sitemap, RSS or API.
The only bulk source is govinfo’s GAOREPORTS collection, which runs from 1989 to 2008 and then stops.
A bid-protest corpus that ends 18 years ago invites a customer to read absence as a finding, which is worse than not serving it.
The line on court material
We carry rules a court formally adopts and publishes as binding on everyone appearing before it. We do not carry an individual judge’s preferences. Formally adopted rules are stable, citable, published under statutory authority, and amended on a visible cycle. That covers the Federal Rules and Supreme Court Rules today, the state court rules in the Coverage matrix, and the federal local rules above. Judge-specific material fails every one of those tests: over 1,500 judges, no consistent location, no citation form, revised or voided silently on rotation. We could ingest it. We could not keep it honest, and a confidently stale answer is worse than none.Related
