Evervault’s Card Insights API provides a powerful, real-time interface for card and cardholder verification checks and enrichment. Card Insights allows you to run address verification (AVS), cardholder name verification (ANI) and CVV validation, perform BIN lookups, gain insight on interchange and network fees, and push/pull transaction capabilities for disbursements and collections. By unifying these inputs, the API provides real-time assessments of card and cardholder authenticity alongside rich card metadata—enabling precise validation and smarter routing, handling, and fraud prevention.

Creating a Card Insight

Card Insights is extensible - you choose the insights you need per request. Every response includes BIN data by default. You can add any of the following extensions:

1. Address Verification (AVS) – Run AVS to verify postal code and street-level elements (line1/line2, city, state, country) against issuer records.
2. Name Verification – Run ANI to verify the provided first and last name against issuer records.
3. Fees – Receive estimated network and interchange fees for specified transaction types to support transparent pricing and optimisation.
4. Transaction Capabilities – Determine push/pull transaction eligibility, network, regulatory status, and expected funds-availability windows.
5. CVV Validation – Validate the CVV against issuer records.
