Vault

Access sensitive card data for agent cards.

Vault endpoints provide access to sensitive card data. Unlike the rest of the Mercury API, Vault endpoints are served from a dedicated host — https://vault-api.mercury.com/api/v1 — so that sensitive data stays isolated from standard API traffic.

Use the Vault API to reveal the full card number, expiration date, and CVC for a card. Card details can be revealed for agent cards only.
