Capabilities
What an integration can rely on
Jurisdiction-aware matching
State-specific source routing avoids treating unlike contractor registers as one generic dataset.
Status and class review
Return licence status, available class/category fields, holder details, and register source context.
Dashboard-to-API migration
Teams can validate the result shape manually before wiring the same checks into their system.
Bulk monitoring
Bulk workflows support periodic contractor list review before teams move to always-on API checks.
Common questions
API buying context
Can WorkClear verify contractor licences across every state?
WorkClear has live public contractor coverage across Australian states and territories, with clear caveats for specialised or not-yet-live source families.
Does the contractor API include South Australia?
Yes. South Australia is live for active CBS PGE and Builder/BLD contractor records, while broader SA categories are handled separately.
Can I search by ABN?
ABN search is supported where register data contains usable ABN details. Exact licence number and holder-name search remain the most reliable inputs.
