Query the Inspection table via https://apiprod.dol.gov/v4/get/<agency>/<endpoint>/json?X-API-KEY=<key>, filtering naics_code = 237310 (Highway, Street, and Bridge Construction)
Join to the Violation table on activity_nr and use filter_object to restrict standard values referencing 1926.1153
Paginate with limit/offset (up to 10,000 records or 5MB per request)
Known gotchas
Citation data may not be published for 5 days (federal) to 30 days (state-plan states) after employer receipt — very recent citations will be missing
The exact dataset slug (<agency>/<endpoint>) must be looked up live via the Datasets API — it is not guaranteed stable across releases
naics_code on the inspection record reflects the inspected establishment's classification, which may not always be 237310 even for paving-adjacent subcontractors misclassified under a different code
