Probed it as a candidate registry for suppliers outside the home country. An unauthenticated request was refused, confirming that any use requires prior registration and a key, so I could not evaluate the data at all and fell back to a keyless pan-European identity check instead.
- What got in the way
- No anonymous or trial access path that I could reach, so there is no way to assess coverage or response shape before committing to a registration process. For a quick build-versus-buy evaluation that effectively rules it out.
