# Indian Space Portal & ISRO API (llms.txt)

> The ultimate digital gateway to India's space ecosystem.

This platform consists of two main components optimized for AI and developers:
1. **The Space Hub (Main App)**: A comprehensive web portal (`https://space.veerexa.com`) for browsing Indian space assets, launch vehicles, upcoming mission countdowns, and the private space sector.
2. **The ISRO API (Developer Portal)**: A free RESTful web service (`https://space.veerexa.com/api/v1`) providing structured JSON data about the Indian Space Research Organisation (ISRO).

## 1. The Space Hub (Main App)
The main application provides visually rich, semantically structured pages for:
- **Active Orbital Assets**: Real-time tracking and metadata for active Indian satellites (e.g., INSAT, GSAT, Cartosat).
- **Heavy Lift Vehicles**: Detailed operational specs of ISRO's rockets (PSLV, GSLV, LVM3, SSLV).
- **Mission Control**: T-minus countdowns for upcoming orbital insertion missions.
- **The Private Sector**: Information about emerging private Indian space startups (e.g., Skyroot, Agnikul).

**Important Links (Web):**
- Home: `https://space.veerexa.com`
- Spacecraft Explorer: `https://space.veerexa.com/spacecrafts`
- Launcher Database: `https://space.veerexa.com/launchers`

## 2. ISRO API (Developer Portal)
The API is designed to be easily accessible for developers and Large Language Models.

### Key Capabilities
- **Spacecraft Data**: Deep metadata on Indian satellites (INSAT, GSAT, Cartosat, Chandrayaan).
- **Launchers**: Historical records for PSLV, GSLV, and LVM3 rockets.
- **Missions**: Detailed stats for landers, rovers, and payloads.

### API Resources
- API Base URL: `https://space.veerexa.com/api/v1`
- Documentation: `https://space.veerexa.com/developers/docs`
- Pricing: 100% Free up to 1,000 requests/hour

### Example Request
```bash
curl -X GET "https://space.veerexa.com/api/v1/spacecrafts?search=chandrayaan" \
  -H "Authorization: Bearer YOUR_API_KEY"
```

## JSON-LD Architecture
Both the Main App and the Developer Portal heavily use JSON-LD schemas (`WebPage`, `WebAPI`, `FAQPage`, `ItemList`) so AI systems and search engines can extract factual answers automatically. 

## Frequently Asked Questions
- **Is there a free ISRO API?** Yes, the Indian Space Portal provides a free ISRO API up to 1,000 requests/hour.
- **How to get Indian satellite data?** Use the `/api/v1/spacecrafts` endpoint.
- **How to authenticate?** Use Bearer Tokens in the Authorization header (`Authorization: Bearer YOUR_API_KEY`).
- **Is this an official ISRO portal?** No, it is an independently maintained aggregate of public domain ISRO data.
