Short, high-intent examples that are easy to open, share, and understand for search engines and AI systems.

Order validation

Validate order JSON against a schema

Check orderId, total, and paid field types before API input reviews or config releases.

Open example
Missing required

Find a missing customerEmail required field

The schema requires customerEmail and items, while the sample response omits customerEmail for required-field debugging.

Open example
Enum mismatch

Debug an enum compatibility failure

The schema only allows draft, published, and archived, while the sample response uses processing.

Open example
Type drift

Catch number and boolean values drifting into strings

The sample turns orderId, total, and paid into strings, useful for API type-drift checks.

Open example
oneOf branch

Debug a oneOf payment branch conflict

The sample sets method=card but sends bankAccount, useful for reviewing oneOf branches, const rules, and mutually exclusive fields.

Open example
Format error

Catch invalid email and URL formats

customerEmail and callbackUrl use invalid formats, useful for confirming format constraints before release.

Open example
if/then rule

Validate an if/then conditional requirement

When contactMethod=email the payload must include customerEmail, useful for checking conditional required rules.

Open example
Dependent required

Check creditCard triggering billingAddress

The sample includes creditCard but omits billingAddress, useful for dependentRequired field validation.

Open example
Shipping dependency

Check shippingAddress triggering recipientPhone

The payload has a shipping address but no recipient phone, useful for testing dependent required fields locally.

Open example
allOf rules

Debug multiple allOf rules failing together

The sample fails userId type, role enum, and limits.api minimum constraints, useful for allOf aggregate checks.

Open example
anyOf branch

Debug an anyOf contact branch mismatch

Neither the email nor phone branch matches, useful for explaining why an anyOf contact schema fails.

Open example
not rule

Debug a not rule blocking production test mode

The sample forbids production with testMode=true and also misses the billing feature, useful for release-gate checks.

Open example
contains array

Debug a contains array missing an active admin

No array item is both role=admin and active=true, useful for explaining why a contains constraint fails.
