Extract inspection report data for all registered audit firms from the US Public Company Accounting Oversight Board (PCAOB). Returns firm name, country, global network affiliation (Big-4 etc.), inspection year, Part I.A audit-deficiency counts, and direct links to inspection report PDFs.

What it does

The PCAOB publishes a pre-built public JSON feed of all firm inspection reports. This actor fetches that feed (4,000+ records covering 2003–2025) and returns filtered, structured records matching your search criteria.

Each output record covers one audit firm for one inspection year and includes:

• Firm identity — registration ID, name, country, Big-4 network affiliation
• Inspection summary — year, report date, inspection type (annual/triennial)
• Deficiency metrics — total audits reviewed, number with Part I.A deficiencies, deficiency rate
• Audit client data — total issuer clients, integrated audits, financial-statement-only audits
• Report link — direct URL to the full PDF inspection report

Use cases

• SEC compliance — identify firms with elevated deficiency rates before engaging them
• Audit-quality research — track deficiency trends across firms, years, and global networks
• Securities litigation — source inspection findings for plaintiff-side cases
• Big-Four competitive intelligence — benchmark network-level inspection outcomes
