<pre>
  \`Public, unauthenticated. Shows the invitation a join link is for while it is open: who asked, the address it went to, and the directory values that will be prefilled. The token is the authentication.

  Endpoint:
  GET [https://verification.didit.me/v3/travel-rule/join/\{token}/](https://verification.didit.me/v3/travel-rule/join/\{token}/)

  Authentication:
  None - the invitation token in the URL is the credential.

  Failure modes:

  * 404 - No invitation has this link.
  * 410 - The invitation is no longer open: expired, already used, or withdrawn.
