Provenance and freshness

  • Internal Revenue Service: EO BMF, Publication 78, auto-revocations, 1023-EZ approvals, Form 990 e-file releases, Form 990 website fields, and Section 527 Form 8871 and 8872 records. Source
  • Federal Election Commission: Committee master records, filings, whole-report PDFs, and itemized Schedule A receipts mirrored to link Section 527 organizations to federal committees. Source

  • Live coverage and cycle bookkeeping: Public status verified 2026-09-08 reports 1,983,563 organizations, 1,435,544 Publication 78 rows, 1,187,976 revocations, 509,064 1023-EZ approvals, 4,608,757 mirrored e-filed returns, 2,212,937 identifiers and indexed website domains, 59,128 Section 527 organizations, 77,182,209 FEC contribution records, and 1,837,841 geocoded organizations.

Update cadence: Monthly IRS release cycles, currently 2026-07 for the EO Business Master File and Publication 78 and 2026-08 for auto-revocations, with annually promoted Form 990 e-file releases whose 2026 release was promoted 2026-08-28, 2026 FEC cycles, 1023-EZ data current only to 2023, and a cron-triggered archive-first refresh handoff.
Metadata verified: 2026-09-08

Governance: The service is an IRS and FEC mirror, not an authority: records are reproduced from published bulk releases and remain release-based rather than real-time, and read-time overrides are recorded explicitly to preserve mirror purity. Coverage is uneven across cycles because upstream release schedules differ, and 1023-EZ approval data is only current to the 2023 release. Geocoding is derived rather than authoritative: 145,722 of 1,983,563 organizations are unmatched and precision ranges from rooftop to postal-centroid. Master canonical identifier links to the corporate entity graph are not yet populated. The service does not publish llms.txt or an RFC 9727 catalog, and its OpenAPI document omits operationId, so the operations recorded here are catalog-curated identifiers for verified public routes.

Agent readiness

Partial · 78/100 78%

Live status, source bookkeeping, OpenAPI 3.1, HTML documentation, citation permalinks, and 44 verified public read operations are published. The upstream document omits operationId and response examples, and neither llms.txt nor RFC 9727 discovery is served, so the recorded operation identifiers are catalog-curated rather than upstream-authoritative.
