PDF Generation SDKs

cloudlayer.io provides official PDF generation SDKs for .NET (C# and F#), Go, Java, JavaScript/TypeScript, PHP, Python, and Ruby. Convert HTML to PDF, capture URLs as documents, and render templates from your application. Since all document generation is driven by a REST API, you can also integrate directly from any language that supports HTTP requests.

Official SDKs

Clients in development

Rust and Swift clients exist as source on GitHub and are not yet published to a package manager: Rust and Swift. Until they ship, call the REST API directly from those languages.

Using the REST API Directly

The cloudlayer.io REST API can be called from any language. All you need is:

1. Your API key (passed via the X-API-Key header)
2. The ability to make HTTP POST requests with JSON bodies
3. Base URL: https://api.cloudlayer.io/v2

Quick Reference: API Endpoints

cURL Example

curl --request POST \
  --url https://api.cloudlayer.io/v2/url/pdf \
  --header 'Content-Type: application/json' \
  --header 'X-API-Key: <YOUR-API-KEY>' \
  --data '{
    "url": "https://example.com",
    "async": false
  }'

JavaScript (Node.js / Bun / Deno)

const response = await fetch("https://api.cloudlayer.io/v2/url/pdf", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "X-API-Key": "<YOUR-API-KEY>",
  },
  body: JSON.stringify({
    url: "https://example.com",
    async: false,
  }),
});

const result = await response.json();
console.log(result.assetUrl);

Python

import requests

response = requests.post(
    "https://api.cloudlayer.io/v2/url/pdf",
    headers={
        "Content-Type": "application/json",
        "X-API-Key": "<YOUR-API-KEY>",
    },
    json={
        "url": "https://example.com",
        "async": False,
    },
)

result = response.json()
print(result["assetUrl"])

Tip: Even if your language does not have a dedicated SDK, the REST API is straightforward to use. See the Authentication Examples, HTML Examples, and URL Examples for more language-specific code samples.
