commentlettercheck

Look up whether a US-listed ticker has any SEC comment-letter correspondence on file (staff review letters and company responses, form types UPLOAD/CORRESP). Returns a free-tier preview: filing count and most recent filing date, sourced live from SEC EDGAR. Does not include letter content or severity scoring -- the per-letter severity breakdown is a separate $39 report at https://www.edgethirteen.com/tools/commentlettercheck.
