Get envelope expiration when created?

Using the Docusign eSignature API, I’m able to send envelopes w/o any issues. I am not setting the expiration date when sending the envelope, but do have a setting on my account with a value of 3 days. My question is, is there a way to get the value of the expiration date (or days that the expiration date is configured for) when the envelope is created, without an additional request being sent via the API to retrieve the envelope details or to get the value from my account?

I’m trying to avoid bumping up against any rate limits.
