How to generate a PDF from HTML in cURL

Use the Inkspan /v1/generate/html endpoint to generate a PDF from HTML in cURL. 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.

cURL example

curl -X POST https://api.inkspan.dev/v1/generate/html \
  -H "X-API-Key: ink_live_..." \
  -H "Content-Type: application/json" \
  -d '{"html":"<h1>Hello</h1>"}' --output out.pdf

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.
