Overview

NoctuaSky is a sky observation platform and its API gives you access to astronomical data like star positions, constellations, and celestial events. No authentication is required for basic endpoints, making it easy to get started exploring the night sky programmatically. It is a good fit for hobbyist developers building astronomy apps or planetarium tools.

💡

Beginner Tip

Check the Swagger documentation at the API URL first — it provides an interactive interface where you can test endpoints directly in your browser without writing any code.

Available Data

Noctua data via REST API
JSON-formatted response data
Freely accessible without authentication

Example Response

JSON Response 
{
  "status": "success",
  "data": {
    "result": "Data from Noctua",
    "description": "REST API used to access NoctuaSky features",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

id Unique identifier for the celestial object in the NoctuaSky database.
name Common or catalog name of the astronomical object (e.g., star name or NGC designation).
ra Right ascension of the object in degrees, used for locating it in the sky.
dec Declination of the object in degrees, the celestial equivalent of latitude.
magnitude Apparent magnitude (brightness) of the object — lower values mean brighter.

Implementation Example 

const url = "https://api.noctuasky.com/api/v1/swaggerdoc/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

404 Not Found The endpoint path or version number in the URL is incorrect.
✓ Always check the Swagger docs at https://api.noctuasky.com/api/v1/swaggerdoc/ for the current list of valid endpoints.
CORS error in browser The API may not have CORS headers enabled for all endpoints.
✓ Make requests from your server-side code rather than directly from the browser to avoid CORS issues.
Empty response body Some endpoints require query parameters like location coordinates that were not provided.
✓ Review the Swagger docs for required parameters — many sky data endpoints need latitude/longitude to be useful.
