Bearer Token Authentication

The most secure way to authenticate API requests is using a Bearer token in the Authorization header.

Usage

Include your API key in the Authorization header:

curl -X POST https://api.renderscreenshot.com/v1/screenshot \
  -H "Authorization: Bearer rs_live_xxxxx" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

Benefits

• Secure: Key is not visible in URLs or logs
• Standard: Uses the OAuth 2.0 Bearer token format
• Flexible: Works with all HTTP methods

Code Examples

Java

import okhttp3.*;

OkHttpClient client = new OkHttpClient();

MediaType JSON = MediaType.get("application/json");
String body = "{\"url\": \"https://example.com\"}";

Request request = new Request.Builder()
    .url("https://api.renderscreenshot.com/v1/screenshot")
    .header("Authorization", "Bearer rs_live_xxxxx")
    .post(RequestBody.create(body, JSON))
    .build();

Response response = client.newCall(request).execute();

Node.js

const response = await fetch('https://api.renderscreenshot.com/v1/screenshot', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer rs_live_xxxxx',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    url: 'https://example.com',
    preset: 'og_card'
  })
});

PHP

$ch = curl_init('https://api.renderscreenshot.com/v1/screenshot');

curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => [
        'Authorization: Bearer rs_live_xxxxx',
        'Content-Type: application/json'
    ],
    CURLOPT_POSTFIELDS => json_encode([
        'url' => 'https://example.com'
    ])
]);

$response = curl_exec($ch);
curl_close($ch);

Python

import requests

response = requests.post(
    'https://api.renderscreenshot.com/v1/screenshot',
    headers={
        'Authorization': 'Bearer rs_live_xxxxx',
        'Content-Type': 'application/json'
    },
    json={'url': 'https://example.com'}
)

Ruby

require 'net/http'
require 'json'

uri = URI('https://api.renderscreenshot.com/v1/screenshot')
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true

request = Net::HTTP::Post.new(uri)
request['Authorization'] = 'Bearer rs_live_xxxxx'
request['Content-Type'] = 'application/json'
request.body = { url: 'https://example.com' }.to_json

response = http.request(request)

When to Use

Use Bearer token authentication when:

• Making server-side API calls
• Building backend integrations
• Maximum security is required
