# arXiv API Guide
## Overview
The arXiv API provides programmatic access to the arXiv preprint repository, one of the most important open-access archives in the sciences. Founded in 1991, arXiv hosts over 2.4 million scholarly articles across physics, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics.
Researchers use the arXiv API to build literature review tools, monitor new submissions in their fields, and integrate preprint search into automated research workflows. The API returns results in Atom XML format with rich metadata including titles, authors, abstracts, categories, DOIs, and journal references.
The API is free to use with no authentication required. It supports complex boolean queries across multiple fields and allows sorting by relevance, submission date, or last-updated date.
## Authentication
No authentication required. The arXiv API is fully open. However, users must respect the rate limit of 3 requests per second. Excessive usage may result in temporary IP-based blocking. Including a descriptive User-Agent header is considered good practice.
