How to generate a PDF from HTML in Node.js

Use the Inkspan /v1/generate/html endpoint to generate a PDF from HTML in Node.js. It runs as a managed API — no headless-browser infrastructure, fonts, or scaling to maintain. Authenticate with your API key and send a single POST request.

Node.js example

const res = await fetch('https://api.inkspan.dev/v1/generate/html', {
  method: 'POST',
  headers: { 'X-API-Key': 'ink_live_...', 'Content-Type': 'application/json' },
  body: JSON.stringify({"html":"<h1>Hello</h1>"})
});
fs.writeFileSync('out.pdf', Buffer.from(await res.arrayBuffer()));

Notes

Authentication: pass your key in the X-API-Key header.
Pricing is usage-based; the free tier covers 100 documents/month.
Extraction endpoints return a confidence score so you never ship false-certain data.
