JSON Validator: common questions
How does JSON Validator handle my input?
Processing happens on your device. OmniKit does not upload or save your tool input or results.
Do I need an account for JSON Validator?
No account is required for the main tool. Optional favorites and account features are separate from processing your input.
Does JSON Validator check an API’s business rules?
It checks JSON syntax, not a custom schema, required business fields or whether an API response is correct.
