# National Australia Bank (NAB)

> National Australia Bank (NAB) is one of Australia's "Big Four" banks and a mandated Consumer Data Right (CDR) data holder. It exposes a public, unauthenticated Product Reference Data (PRD) API conforming to the DSB Consumer Data Standards (CDS) Banking API, alongside an accredited-only consumer data-sharing surface. Base URL: https://openbank.api.nab.com.au/cds-au/v1

## APIs

- [NAB CDR Product Reference Data API](https://developer.nab.com.au/docs/open-banking): Public GET /banking/products and /banking/products/{productId} returning NAB's banking product catalogue (home loans, deposits, credit cards, business products) with fees, rates, eligibility and terms.

## Specs
