# Retrieve Inquiry - Cyber Only
source: https://developer.mastercard.com/onboard-risk-check/documentation/use-cases/orc-cyber/inquiry-history-request/index.md

Note: Customers are encouraged to use the [Retrieve Inquiry endpoint](https://developer.mastercard.com/onboard-risk-check/documentation/use-cases/orc/retrieve-inquiry/index.md) to obtain a comprehensive risk assessment.

This legacy API is used **ONLY** to get results for CyberHealth risk assessment. Customers must use the IRN received from the [Cyber Only Initiate Inquiry endpoint](https://developer.mastercard.com/onboard-risk-check/documentation/use-cases/orc-cyber/create-history-request/index.md) or a MATCH Inquiry. Ratings will be both numerical and alphabetical.

There is no limit to the number of times results can be reviewed. Results are available for up to thirty days using this endpoint.
