PDF Generation SDKs

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

Using the REST API Directly

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

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

Quick Reference: API Endpoints

Endpoint	Description
`POST /url/pdf`	Convert a URL to PDF
`POST /url/image`	Convert a URL to an image
`POST /html/pdf`	Convert HTML to PDF
`POST /html/image`	Convert HTML to an image
`POST /template/pdf`	Generate a PDF from a template
`POST /template/image`	Generate an image from a template
`GET /url/pdf`	Simple URL to PDF (query params only)
`GET /url/image`	Simple URL to image (query params only)

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.
