Validate a labor classification API

Use deterministic keyword matching against a selected wage determination. Ambiguous work is routed for human conformance review.

The Validate a labor classification operation is part of the Prevailing Wage API on BRAINIAC.software. Use deterministic keyword matching against a selected wage determination. Ambiguous work is routed for human conformance review. It is exposed as POST /api/v1/prevailing-wage/classification-validate and priced at $0.02 USDC on Base. Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: Official SAM.gov and Department of Labor wage determinations. Limitations: Verify wage rates against the current official determination before relying on results. Payroll outputs are prechecks and editable reports, not government-certified filings. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings. Related operations in this group include Search Davis-Bacon wage determinations, Resolve a wage determination, Read classification rates, Draft a classification conformance request.
