Requires catalog:write. An already queued/running scan is reused. This only refreshes duplicate evidence; it does not merge, publish or delist products. Read completion with products.getDuplicateScan, then list status=duplicates, duplicateType=sku, detail=full and page all matching results before previewing a merge. Uses the same 5,000-candidate scan limit as the UI. ## OpenAPI ````yaml /openapi.json post /api/v1/products/duplicates/scan openapi: 3.1.0 info: title: OmniCommerce API version: 1.0.0 license: name: Proprietary url: https://omnicommerce.sg/terms description: >- OmniCommerce API surface for agents and developer integrations.
