Make sure your notebook is **public**.\n2. Copy the trail end of your notebook's URL. For example, if your original notebook URL is `https://observablehq.com/@rk2546/2025-infovis-cse_week-5-lab`, then you will only need `@rk2546/2025-infovis-cse_week-5-lab`.\n3. Paste the tail end onto a new URL base: `https://api.observablehq.com/document/`. In our example, the new URL will be `https://api.observablehq.com/document/@rk2546/2025-infovis-cse_week-5-lab`\n4. Navigate to the new URL and, if successful, you should get a JSON output. Find the `thumbnail` item; this ID is pasted inside of each element inside of your preview array.","pinned":false,"hidden":false,"mode":"md","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"","database":"$undefined"},{"id":426,"value":"viewof query_notebook_url = Inputs.text({label: \"Notebook URL\", placeholder: \"Enter the notebook URL\", value: \"\"})","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":433,"value":"{\n const r = get_api_url(query_notebook_url);\n if (r == null) return htl.html`
