Overview
NASA ADS (Astrophysics Data System) is a digital library for astronomy and physics research papers, with millions of articles going back decades. The API lets you search, retrieve, and cite scientific literature programmatically using an OAuth token. It is ideal for researchers and developers building tools around academic astronomy content.
Beginner Tip
Generate your personal API token from the ADS user account page — it is a Bearer token you include in the Authorization header, and it gives you access to all search and retrieval features.

numFound Total number of papers matching your search query across the entire database. docs Array of paper objects returned for the current page of results. title Array containing the paper title as a string (wrapped in array for consistency). author List of author names in "Last, First" format. bibcode The unique ADS identifier for a paper, useful for fetching full details or generating citations. year The publication year of the paper as a four-digit string. Implementation Example
// ⚠️ Note: This URL may be a documentation page. Check official docs for actual API endpoint.
const url = "https://ui.adsabs.harvard.edu/help/api/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
headers: {
"Authorization": "Bearer YOUR_API_KEY"
}
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
