Quickstart

Learn how to verify online media using Content Credentials API.

  1. Create an API key

    You can get an API key by signing up at RapidAPI.

  2. Gather Content Credentials for a media URL. In this example, we will use https://opensource.contentauthenticity.org/img/Sunset.jpg.

    Example media

    const request = require('request');

const options = {
  method: 'POST',
  url: 'https://content-credentials.p.rapidapi.com/verify',
  headers: {
    'Content-Type': 'application/json',
    'X-RapidAPI-Key': 'YOUR-API-KEY',
    'X-RapidAPI-Host': 'content-credentials.p.rapidapi.com'
  },
  body: {
    url: 'https://opensource.contentauthenticity.org/img/Sunset.jpg'
  },
  json: true
};

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});

    <?php

$client = new http\Client;
$request = new http\Client\Request;

$body = new http\Message\Body;
$body->append(json_encode([
    'url' => 'https://opensource.contentauthenticity.org/img/Sunset.jpg'
]));
$request->setRequestUrl('https://content-credentials.p.rapidapi.com/verify');
$request->setRequestMethod('POST');
$request->setBody($body);

$request->setHeaders([
    'Content-Type' => 'application/json',
    'X-RapidAPI-Key' => 'YOUR-API-KEY',
    'X-RapidAPI-Host' => 'content-credentials.p.rapidapi.com'
]);

$client->enqueue($request)->send();
$response = $client->getResponse();

echo $response->getBody();

    require 'uri'
require 'net/http'

url = URI("https://content-credentials.p.rapidapi.com/verify")

    "X-RapidAPI-Key": "YOUR-API-KEY",
    "X-RapidAPI-Host": "content-credentials.p.rapidapi.com"
}

response = requests.post(url, json=payload, headers=headers)

print(response.json())

    package main

import (
    "fmt"
    "strings"

    "io"
)

func main() {

    url := "https://content-credentials.p.rapidapi.com/verify"

    payload := strings.NewReader("{\"url\": \"https://opensource.contentauthenticity.org/img/Sunset.jpg\"}")

    req, _ := http.NewRequest("POST", url, payload)

    req.Header.Add("X-RapidAPI-Key", "YOUR-API-KEY")
    req.Header.Add("X-RapidAPI-Host", "content-credentials.p.rapidapi.com")

    res, _ := http.DefaultClient.Do(req)

    defer res.Body.Close()
    body, _ := io.ReadAll(res.Body)

    fmt.Println(res)
    fmt.Println(string(body))

}

    HttpRequest request = HttpRequest.newBuilder()
        .uri(URI.create("https://content-credentials.p.rapidapi.com/verify"))
        .header("Content-Type", "application/json")
        .header("X-RapidAPI-Key", "YOUR-API-KEY")
        .header("X-RapidAPI-Host", "content-credentials.p.rapidapi.com")
        .method("POST", HttpRequest.BodyPublishers.ofString("{\"url\":\"https://opensource.contentauthenticity.org/img/Sunset.jpg\"}"))
        .build();
HttpResponse<String> response = HttpClient.newHttpClient().send(request, HttpResponse.BodyHandlers.ofString());
System.out.println(response.body());

    import Foundation

let headers = [
    "Content-Type": "application/json",
    "X-RapidAPI-Key": "YOUR-API-KEY",
    "X-RapidAPI-Host": "content-credentials.p.rapidapi.com"
]
let parameters = ["url": "https://opensource.contentauthenticity.org/img/Sunset.jpg"] as [String : Any]

let postData = JSONSerialization.data(withJSONObject: parameters, options: [])

let request = NSMutableURLRequest(url: NSURL(string: "https://content-credentials.p.rapidapi.com/verify")! as URL,
                                        cachePolicy: .useProtocolCachePolicy,
                                    timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = postData as Data

let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
    if (error != nil) {
        print(error as Any)
    } else {
        let httpResponse = response as? HTTPURLResponse
        print(httpResponse)
    }
})

dataTask.resume()

  3. The API returns a JSON output with 2 keys: manifest_store and resources.

    manifest_store contains active_manifest and all historical manifests, data describing the source media, editing history and if applicable, AI tools used to generate the final media.
