SEC EDGAR (free, public, bulk-OK at 10 req/sec) is the goldmine -- per-issuer
state of incorporation, business/mailing address, phone, SIC, entity type via
company_tickers_exchange.json + submissions/CIK*.json. ~2,771 OTC SEC filers;
~35% US-domestic (~970), of which DE+NV = 73% -> the reincorporate-to-Texas /
registered-agent / annual-report / foreign-qualification target list. EDGAR has
no email (enrich from IR pages or direct mail/call). Texas reincorporation is a
real early trend (48/43 EDGAR filings; TBOC Ch.10 conversion, Texas Business
Court, TXSE). CAN-SPAM compliant B2B; filter to US states to avoid CASL/GDPR.
