    The way they used our search library is kind of interesting. They could've
    copied the code locally and modified it to work with the Substack API, but I
    guess Substack doesn’t have an API?

Substack doesn't have an API. Their editor is laughably primitive compared with other solutions. Their visual look hasn't changed at all since their inception. They don't have discoverability. Can anyone tell me what Substack is doing with all the millions of dollars of funding they've taken? We joke about Twitter being massively overstaffed, but Substack, to me, looks just as bloated, organizationally.
