Can I validate my Product JSON-LD if my offers block is dynamic (price changes per customer group)?
Check the markup generated for the relevant store, currency and visitor context, then compare it with the visible offer. This tool can examine the pasted top-level Product shape, but it does not run Magento pricing, inspect customer-group rules or validate nested offers completely. Use actual public page evidence and the current Product feature guide; a local score cannot establish whether every price or cache variant is correct.
