Converting Between USD and USDC

The Coinbase Pro API had a convert currency endpoint for converting between USD and USDC. Per the " Pro API Mapping", there does not appear to be any comparable endpoint in the Advanced Trade API. There is no USDC-USD pair, as the currencies are considered “unified”. I’m a bit confused about what exactly “unified” means, as it appears that I cannot buy any XXX-USD pair with USDC directly.

Is there any way to programmatically convert between USD and USDC via Advanced Trade, or trade XXX-USD pairs with USDC? Thanks!

Hello @TheHeurist! We understand that you are looking for a convert currency API for Advance Trade as that of Coinbase Pro API, however we would like to inform you that there is no direct way in the Advanced Trade API to convert crypto into fiat.
We currently do not have an API endpoint to convert USDC to USD. Instead, you may utilise the Create Orders endpoint:

  • By placing a buy order using the Create Order endpoint, you may trade crypto (USDC) to fiat (USD) or other product_id.

It is important to note that placing a buy order is subject to fees. You may visit this Help Center for more information about Advanced Trade fees.

On you query related to USD- USDC ‘unified’ - USD and USD Coin (USDC) is now unified in Coinbase Exchange, a specialized Coinbase product that is intended for institutional traders and investors.
