Additional context

Creating a link on pobl.ink:

curl -d '{"content":"<POB generated code>"}' \
       -H "Content-Type: application/json" \
       -X POST https://pobl.ink/v1/create

Response:

{"id":"d0GVPM87"}

The id is always [a-zA-Z0-9]{8}.

Querying the resulting URL https://pobl.ink/d0GVPM87 will return a string of the submitted POB code (provided link is just dummy data).
