I've already tried the approach in this answer, but I'm getting this error:

IBMQuantumExperience.IBMQuantumExperience.CredentialsError: error during login: License required. You need to accept the License from Web Platform. https://quantumexperience.ng.bluemix.net

However, I've already accepted the terms, and have already successfully run two experiments using the Qiskit SDK, like the ones in the docs.

I'm suspecting IBMQuantumExperience, and by extension qiskit-api-py might be out of date, superceded by qiskit. My question is then this: is it possible to check my remaining credits using the new library, and if so, how? If not, how else can I check my credits?

You are correct that IBMQuantumExperience is a deprecated library. Anything you wanted to use IBMQuantumExperience to do you can now do through qiskit-ibmq-provider.

To answer your main question, the credit system is being removed in the future, so there is currently no way to check your remaining credits. The feature used to be in the old IBM Q Experience page, but since the new, beta version has been launched it no longer has that capability.

    $\begingroup$ @silgon At the moment, the credit system is still in place, but it was reworked. Users now can have up to 5 jobs submitted at any on time. Once they hit that 5 job limit, they must wait until at least one of those jobs finish before being able to send another. $\endgroup$ Commented Apr 8, 2020 at 13:29

    $\begingroup$ @Andrea As far as I know, independent of those factors, yes. $\endgroup$ Commented Apr 13, 2020 at 17:37
