# List Kernel Specs

`GET /v1/kernel/kernelspecs`

The kernels a cloud sandbox can start.

Not proxied upstream: the gateway enumerates with a ``KernelSpecManager``
on its own host, which in cloud is the API container and has none of the
sandbox's kernelspecs — so proxying returned an empty list and the kernel
picker had nothing to offer. The sandbox images' kernels are a declared
fact (:func:`cloud_kernel_specs`), and answering from that also lets the
picker work before any box exists, which is exactly when a user chooses.
