wikidata-isbn.js

const Cite = require('citation-js')

const isbn = '978-1-4088-4564-6'

// search ISBN-13 or ISBN-10 (note hyphens and case-sensitivity)

const sparql = `
SELECT DISTINCT ?subject WHERE {
  ?subject wdt:P31 wd:Q7725634.

}
`

const url =
  'https://query.wikidata.org/sparql?format=json&query=' +
  encodeURIComponent(sparql)

console.log(url)

fetch(url)
  .then(response => response.json())
  .then(data => data.results.bindings[0].subject.value.split('/').pop())
