Status-only (no bond/insurance match, or statusOnly: true) | $0.01 |
Miss (found: false) | FREE |
| State | Status | Source | Bond + Insurance |
|---|---|---|---|
| WA | ✅ Live | WA L&I open data (data.wa.gov) | ✅ Real data (bzff-4fmt + ciwg-agsx datasets) |
| CA | ⚠️ Beta | CSLB HTML (cslb.ca.gov) | ✅ Parsed when CSLB is up |
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_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.
| Event | Price |
|---|---|
license-verification | $0.03 — full result (status + bond + insurance) |
status-only-result | $0.01 — status found, no bond/insurance match (or statusOnly: true) |
Charged only on found: true. Validation errors, not-found results, and source failures are not charged.
