PHP SDK

The official PHP SDK for the Drishti API provides a synchronous HTTP client with named-argument methods, a low-level request method, and a blocking websocket client for long-running workers.

Requirements

• PHP 8.2+ with ext-json
• Composer
• A valid Drishti API key

Installation

composer require manasija/drishti-sdk

Package: manasija/drishti-sdk on Packagist.

Quick start

<?php

require 'vendor/autoload.php';

use Drishti\DrishtiClient;

$client = new DrishtiClient(apiKey: getenv('DRISHTI_API_KEY'));

$news = $client->getNews(symbols: ['RELIANCE', 'TCS'], limit: 10);
echo count($news['data']);

JSON responses are returned as associative arrays. CSV, PDF, and JSONL responses are returned as strings. Failed requests throw Drishti\Exception\DrishtiApiException with getStatusCode() and getBody().

WebSocket session

PHP web requests cannot hold a socket open, so run the websocket client as a long-running CLI worker, for example under supervisord or systemd. run() blocks, reconnects after disconnects, and resubscribes every product until you call stop().

<?php

require 'vendor/autoload.php';

use Drishti\DrishtiClient;

$client = new DrishtiClient(apiKey: getenv('DRISHTI_API_KEY'));

$ws = $client->websocket(
    onOpen: fn (string $reason) => print("connected
"),
);

$ws->onAnnouncements(function (array $announcement): void {
    echo $announcement['symbol'], ' ', $announcement['summary'] ?? '', PHP_EOL;
});

$ws->subscribe('announcements', symbols: ['RELIANCE']);
$ws->run();

See the websocket worker example for a complete script.

Batch jobs

$job = $client->postBatchJobsFile(
    fileName: 'batch.jsonl',
    fileContent: file_get_contents('batch.jsonl'),
    displayName: 'Quarterly run',
);
