Requirements

PHP >= 8.1
Composer

Dependencies

Package	Purpose
`guzzlehttp/guzzle` ^7.4	HTTP client for API requests
`symfony/dom-crawler` ^6.0	HTML response parsing
`symfony/css-selector` ^6.0	CSS selector support for DomCrawler

Installation

composer require renderbit-technologies/indos-checker-api

Usage

Check if an INDOS number is valid

use RenderbitTechnologies\IndosCheckerApi\IndosChecker;

$checker = new IndosChecker();
$checker->checkValid('05LL0262', '14/08/1963');
// true

Retrieve seafarer details

$data = $checker->getData('05LL0262', '14/08/1963');
// [
//     "Name"                => "YADAV SANJEEV",
//     "Date of Birth"       => "14-AUG-1963",
//     "INDoS No."           => "05LL0262",
//     "Passport No."        => "M2069200",
//     "Passport Issue Date" => "15-SEP-2014",
//     "Passport Valid To"   => "14-SEP-2024",
//     "CDC No."             => "MUM 133201",
//     "CDC Issue Date"      => "22-MAY-2015",
//     "CDC Valid To"        => "21-MAY-2025",
//     "CDC Issue Place"     => "Mumbai",
// ]

The returned array contains up to 10 fields: Name, Date of Birth, INDoS No., Passport No., Passport Issue Date, Passport Valid To, CDC No., CDC Issue Date, CDC Valid To, and CDC Issue Place. An empty array is returned when no record is found.

Exception handling

use RenderbitTechnologies\IndosCheckerApi\IndosCheckerException;

try {
    $data = $checker->getData($no, $dob);
} catch (IndosCheckerException $e) {
    // Network or server error — inspect $e->getPrevious() for the Guzzle cause
} catch (\InvalidArgumentException $e) {
    // Bad input: empty INDOS number or wrong date format (must be DD/MM/YYYY)
}

IndosCheckerException wraps all Guzzle/HTTP errors (timeouts, connection failures, server errors).
\InvalidArgumentException is thrown for invalid input: empty or whitespace-only INDOS numbers, or DOB not in DD/MM/YYYY format.

Custom HTTP client

Pass a configured GuzzleHttp\Client to override timeouts, proxies, etc.:

$client  = new \GuzzleHttp\Client(['timeout' => 5.0]);
$checker = new IndosChecker($client);

Custom endpoint

Override the default DGS eSamudra endpoint (useful for testing):

$checker = new IndosChecker(null, 'http://staging.example.com/indos');
