Washington is the reliable, production-ready jurisdiction. Official WA L&I open data is served via Socrata JSON — no scraping, no rate limits, bond and insurance data included from dedicated datasets.

California is beta. CSLB does not publish an open API; the provider fetches the HTML detail page directly. CSLB rate-limits or 503s automated requests intermittently. When unavailable, verify_license returns a clean SESSION_ERRORyou are never charged on source failures. Do not rely on CA for production workflows until a stable server-side CSLB run is confirmed.
