response = sampler.sample_ising(h={0: -1}, J={(0,1): -1})
response.states
# [[1,1]]

# with indices
response = sampler.sample_ising(h={'a': -1}, J={('a','b'): 1})
[{index: s for index, s in zip(response.indices, state)} for state in response.states]
# [{'b': -1, 'a': 1}]

C++ example

$ source ./build_gcc.sh
