Invoice PDF API

Tax-ready invoice PDFs from your HTML & JSON.

POST your invoice HTML and the numbers; get back a pixel-perfect, multi-currency PDF rendered by real Chromium. Glyfa formats currency per locale (JPY, EUR, GBP…), lays out tax line items and totals, and hands you a download link — no headless browser to run yourself.

One request, one invoice PDF

curl https://glyfa.dev/v1/documents \
  -H "Authorization: Bearer dk_your_key" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "invoice",
    "html": "<h1>Invoice {{number}}</h1><p>Total: {{currency total ccy}}</p>",
    "data": { "number": "INV-1024", "total": 1480.00, "ccy": "EUR" }
  }'

Returns { "id", "status": "queued" }. Poll GET /v1/documents/{id} for the signed download URL — or pass a callbackUrl and we'll POST you a signed webhook the moment it's ready.

Bring your own tax engine

Glyfa renders documents — it doesn't calculate tax. Send the amounts and rates from Stripe Tax, TaxJar, Avalara, or your own logic, and built-in helpers format them into a clean invoice: multi-currency totals, per-line tax, subtotals, tax totals and breakdowns — all locale-correct. How tax is presented (VAT/GST labels, inclusive vs exclusive) lives in your own template, so you stay in full control of the numbers. Stored compliant templates and multi-jurisdiction presets are on the roadmap.
