What Sejda API is
Sejda API is a paid REST service that converts a web page URL or HTML source into a PDF. Requests authenticate with an API key in the Authorization header, while browser JavaScript can use a publishable key. Conversion settings cover page size, orientation, viewport width, margins, print stylesheets, rendering delay and lazy loading. Documentation includes Bash cURL, Node.js, Python, JavaScript with CORS, Java, PHP and C# .NET examples. Sejda also provides website links for filling and signing or fully editing documents, with optional email return. Its free Save as PDF link allows 10 uses per visitor per hour. Files can come from a website, Google Drive or Dropbox, but Sejda says it offers no document storage. The API does not cover tools such as merge or compress. Requests over 50MB are rejected, and rate limits apply. Paid plans start at $12/mo.

Who it suits
