README

Welcome to the Kolas.Ai Public API documentation! This repository hosts the PHP client for Kolas.Ai's Clean Talk public API, making it easy for developers to integrate Kolas.Ai’s machine learning services into your applications.

Overview

Clean Talk API is designed to classify message categories based on a trained dataset within a configured project. Use this API to accurately categorize messages into types like "Neutral", "Insult", "Spam" , etc. We support different languages, including English, Russian, Ukrainian, and we can add any languages by request (message to info@kolas.ai).

Key Features

• Predict Message Categories: Use the /predictions/predict endpoint to sync classify messages based on your project-specific datasets and /predictions/asyncPredict endpoint to async classify messages.
• High Accuracy: Predictions include probability scores, giving you confidence in the classification results.
• OAuth2 Authentication: Secure access via OAuth2 client credentials flow.

Usage

The Kolas.Ai API follows the OpenAPI 3.1 standard. To get started:

1. Create a new account on the Kolas.Ai platform.
2. Create a new project Clean Talk and configure your datasets.
3. Authentication: Obtain an access token using OAuth2 client credentials.
4. Make Predictions: Send a POST request to /predictions/predict (or /predictions/asyncPredict) with your projectId and messages.
5. Receive Predictions: Retrieve predicted categories and their probabilities in the API response.

Installation

You can install the CleanTalk PHP client via Composer. Run the following command in your project directory:

composer require kolasai/clean-talk-php-client

Authentication

This API uses OAuth2 client credentials for secure access. You’ll need to request a token using your client credentials from the Kolas.Ai platform.

use CleanTalk\KolasAiOAuthClient;

$oauthClient = new KolasAiOAuthClient();
$authResult = $oauthClient->auth(YOUR_CLIENT_ID, YOUR_CLIENT_SECRET);

$authResult contains the access token and expires_in information, which you will use to authenticate your API requests. You need to update token after its expiration.

Example for Sync Request

Once you have your access token, you can make a request like this:

use CleanTalk\CleanTalkPredictionClient;
use CleanTalk\Request\Message;
use CleanTalk\Request\PredictRequest;

$client = new CleanTalkPredictionClient($authResult->getAccessToken());

$response = $client->predict(
    new PredictRequest(
        YOUR_PROJECT_ID,
        [
            new Message('11177c92-1266-4817-ace5-cda430481111', 'Hello world!'),
            new Message('22277c92-1266-4817-ace5-cda430482222', 'Good buy world!'),
        ]
    )
);

foreach ($response->getPredictions() as $prediction) {
echo "MessageId: {$prediction->getMessageId()}\n";
echo "Message: {$prediction->getMessage()}\n";
echo "Prediction: {$prediction->getPrediction()}\n";
echo "Probability: {$prediction->getProbability()}\n";
echo "Categories: " . implode(', ', $prediction->getCategories()) . "\n";

Example Response

MessageId: 11177c92-1266-4817-ace5-cda430481111
Message: Hello world!
Prediction: Neutral
Probability: 0.9036153107882
Categories: Insult, Neutral, Spam

MessageId: 22277c92-1266-4817-ace5-cda430482222
Message: Good buy world!
Prediction: Neutral
Probability: 0.99374455213547
Categories: Insult, Neutral, Spam

Example for Async Request

Once you have your access token, you can make a request like this:

use CleanTalk\CleanTalkPredictionClient;
use CleanTalk\Request\Message;
use CleanTalk\Request\PredictRequest;

$client = new CleanTalkPredictionClient($authResult->getAccessToken());
$client->asyncPredict(new PredictRequest(
    YOUR_PROJECT_ID,
    [
        new Message('11177c92-1266-4817-ace5-cda430481111', 'Hello world!'),
        new Message('22277c92-1266-4817-ace5-cda430482222', 'Good buy world!'),
    ]
));

Responses will be sent to the configured webhook URL in your project settings.
