# Radian # Radian A mortgage-insurance carrier, fourth in the committed mortgage-insurance ordering. Radian is one of the licensed carriers reached through Insurance. A caller sends the loan and the borrower; the product works down the carrier ordering and returns every carrier willing to insure the loan together with the terms each offered. Eligibility and price are separate questions here. A carrier can qualify a loan and be uncompetitive on premium, so the response carries the full eligible set rather than a single selection, and the choice is left to the caller. ## Products it serves - Insurance - Connection ## Position in the ordering - Mortgage Insurance essentarchenactradianmgicnationalmi ## How this integration is built - **connection configuration** — The wire protocol. One repository per vendor API call, not per vendor. - **language configuration** — The field mapping between the vendor's vocabulary and the canonical model. - **flow file** — The four-way translation: canonical request, vendor request, vendor response, canonical response. - **waterfall priority** — One line naming where this vendor sits in the vertical's ordering. - **status call** — Activating the vendor for a lender, optionally with the lender's own credentials. ## Evidence This vendor is on the roster because each of the following resolves to a committed artifact. - `StaircaseAPI/insurance-data product/data/waterfall/waterfall.json waterfall` - `insurance-data product/data/flows/radian.json`
