Launch Library 2

API

Comprehensive API for spaceflight launches and events database

Overview

Launch Library 2 API provides RESTful access to a curated database of spaceflight launches, events, rockets, agencies, and launch sites. Core endpoints include /launches (filter by date range, agency, rocket type), /events (space-related events like satellite deployments), /agencies (space organizations), and /rockets (vehicle specs). Responses are in JSON format with detailed fields (e.g., launch window, mission objectives, site coordinates). Ideal for building spaceflight tracking apps, educational platforms, news integrations for launch updates, or research tools analyzing space mission trends. Supports pagination and filtering parameters for efficient data retrieval.
