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_licensereturns a cleanSESSION_ERROR—you are never charged on source failures.Do not rely on CA for production workflows until a stable server-side CSLB run is confirmed.
Agentic-payments eligible— pay-per-event pricing + limited permissions + no Standby mode.
