Requirements

• PHP >= 7.4
• A LL2 API token (Optional)

Installation

Install this library via Composer.

composer require cbzink/launchlibrary

Usage

Setup

Instantiate an instance of the LL2 class

use cbzink\LaunchLibrary\LL2;

$client = new LL2($apiToken, $apiEndpoint);

Parameter	Required?	Description
$apiToken	No	Provide your own API token for increased rate limits. Default none.
$apiEndpoint	No	Provide an alternate API endpoint for switching between prod and dev environments. Default production.

Pagination limits

You can change the pagination limit (default 10) using setPaginationLimit.

$client->setPaginationLimit(30);

$client->getPaginationLimit() // (int) 30

Resources

Currently available resources include Agencies, Astronauts, Docking Events, Events, Expeditions, Launchers, Launches, Locations, Pads, Space Stations, and Spacecraft.

Searching for resources

You can search for resources using the parameters specified in the LL2 API docs.

$results = $client->agencies()->search([
    'country_code' => 'US',
]);

Pagination

Searches are often paginated. An array of resources is available under the results property, and next() and previous() methods are available for moving through pagination.

$agencies = $client->agencies()->search();

// Array of Agency resources.
$resources = $agencies->results;

// Fetch the next page of results
$agencies = $agencies->next();

Retrieving resources

You can retrieve detailed resources by their ID.

$results = $client->agencies()->fetch(123);

Special cases

Events and Launches

Events and Launches have additional Previous and Upcoming endpoints you can access using the SDK. search() and fetch() are available on both.

// Previous
$results = $client->events()->previous()->search();

// Upcoming
$results = $client->launches()->upcoming()->search();

Spacecraft

Spacecraft have an additional Flights endpoint you can access using the SDK. search() and fetch() are available on both.

$results = $client->spacecraft()->flights()->search();
