Using the type index

// fetch all types
const index = await fetch('https://data.designmuseumgent.be/v2/id/types').then(r => r.json())

// show sorted list
index["hydra:member"].forEach(t => {
    console.log(`${t["rdfs:label"]}: ${t.object_count} objects`)
})

// use the filter URL directly
const vazen = index["hydra:member"].find(t => t["rdfs:label"] === "vaas")
const objects = await fetch(vazen.filter).then(r => r.json())
