ok, I feel stupid, but there must be a better way than this! (finding name of unique key in dict)

You want both the key and the value so you can use items():

In [39]: L = [
    ...:    { "some_key": {'a':1, 'b':2}},
    ...:    { "some_other_key": {'a':3, 'b':4}}
    ...: ]

In [40]: [{"value": k, **m} for l in L for k, m in l.items()]
Out[40]:
[{'value': 'some_key', 'a': 1, 'b': 2},
 {'value': 'some_other_key', 'a': 3, 'b': 4}]
