No need to sign up. You can actually find the full list in our docs: https://plaid.com/docs/#long-tail-institutions

Not correct - I had to sign up for an account just now so I could get API keys to hit the endpoint.

Besides, the account is limited at the moment. I get the following error:

    {
      "code": 1306,
      "message": "invalid institution permissions",
      "resolve": "Your Client ID does not have access to this institution endpoint"
    }
