Oauth revoked token

Question

Is there any way to determine if an oauth token has been revoked besides actually making a function call? I am working with an Oauth provider that has a single function call that is time consuming and costs money. On my website, I'd like to be able to determine if my access token is valid withing making that call. Thanks

Regrettably the OAuth specification does not provide a standard mechanism.

It would perhaps be appropriate for the OAuth provider to give an additional method to indicate that the token is valid.
