API/Product to exchange USD to ETH, Blockchain Web Services

Hi, developing Blockchain Web Services (doc.bws.ninja) to enable users call Smart Contracts easily. For that purpose we require to exchange USD to ETH just before a user calls our registered smart contracts. Which coinbase product is suitable for such case?
Thank you.

Hello @bws. Welcome to the forum! Thank you for taking interest in our Coinbase API services.

If the requirement is to convert one currency to another, we recommend you to use Coinbase Pro/Exchange API specifically its Conversions endpoint. However, as of now, this endpoint only supports the USDC - USD pair. Hence, there’s still no possible way of exchanging USD-ETH via the API.

You may still explore and track the ETH-USD trading via the Coinbase Pro website which you can find here: https://pro.coinbase.com/trade/ETH-USD

Thank you!

Hello @riza.espiritu … so are you saying currently there is now way to convert trading pair crypto currencies to one another using the conversions api endpoints? Example being converting ETH to BTC then BTC to ATOM.

Hi @FreeMarket! As of now, the conversion endpoint only supports the USDC - USD pair and vice versa. For other currencies such as ETH-BTC, you may use the order endpoint for that. The products list is available via the products endpoint. However, it is important to take note that orders endpoint incur fees and that BTC-ATOM is not yet supported.

Although, it is not something we currently offer. We are constantly working to build products our customers will love. While we can’t offer any specific timeline for the addition of new features, we would like to recommend that you post this in the Feedback Section of the Forum as most new features and improvements to Coinbase come directly from feedback like yours, so it’s very valuable to us.

Thank you so much!
