Worked example
A pasted indicator object with spec_version 2.1, a well-formed id, and created and modified dates is reported as looking valid.
What this tool does not do / Limits
This validator checks only basic structure: type, spec_version, id, created and modified. It is not a complete STIX specification validator and it does not verify that referenced objects exist.
Frequently asked questions
Does this validate the full STIX specification?
No. It checks the basic fields listed above, which catches common structural mistakes but is not a complete specification check.
Is my pasted object sent anywhere?
No. Parsing happens in your browser and nothing is uploaded.
