Interactive intelligence tool
Run the check, then ship the workflow
Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.
Review decision-ready signals
Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.
Automate the workflow that works
Use the request and response examples to turn a one-off check into an API call or recipe.

JavaScript markup
Read markup that tag managers or frameworks add after the page loads with a rendered check.
Example request
GET /v1/structured-data?url=example.comGET /v1/structured-data?url=example.com/product&render=trueBuilt on the same API
The browser experience previews DomScan's structured endpoints, so teams can validate a use case before writing code.
Frequently asked questions
Which schema types are validated?
26 common types, including Product, Offer, Review, Article, Organization, LocalBusiness, BreadcrumbList, FAQPage, Event, Recipe, VideoObject and JobPosting.
Why is my item marked unchecked?
Its type has no validation rules yet. It is still extracted with all its properties.
Does valid markup guarantee rich results?
No. Search engines decide eligibility with their own policies, but valid markup is a requirement.
