# Failed lookup with supplemental data response

> Complete example JSON for the failed lookup with supplemental data.

This sample uses invented data to illustrate the prepared version-2 History API format. Check with LMN whether the contract and multi-provider collection are enabled in your environment. See the [History endpoint reference](/endpoints/history-lookups), [integration guide](/history-integration), and [field definitions](/schemas#vehicle-history-lookups) for interpretation.
