Mendeley REST API

Overview

Mendeley provides a reference management platform with a REST API for programmatic access to personal libraries, group collections, and the Mendeley Catalog — a crowdsourced database of 200M+ academic documents. The API supports OAuth 2.0 authentication, CRUD operations on documents/folders/annotations, and catalog search with rich metadata. Free tier available with registration.

Authentication

Mendeley uses OAuth 2.0 with client credentials or authorization code flow.

# 1. Register app at https://dev.elsevier.com/
# 2. Get access token via client credentials (for catalog search)
curl -X POST "https://api.mendeley.com/oauth/token" \
  -d "grant_type=client_credentials" \
  -d "scope=all" \
  -d "client_id=$MENDELEY_CLIENT_ID" \
  -d "client_secret=$MENDELEY_CLIENT_SECRET"

# Response: { "access_token": "...", "expires_in": 3600, "token_type": "bearer" }

Reader Statistics

Mendeley tracks how many users have saved each paper, providing a real-time measure of scholarly interest (unlike citation counts which lag by months).

def get_popular_papers(topic: str, limit: int = 10) -> list:
    """Find most-read papers on a topic via reader counts."""
    results = search_catalog(topic, limit=limit)
    return sorted(results, key=lambda x: x["readers"], reverse=True)

Rate Limits

Tier	Requests/hour	Catalog access
Free	150	Read-only catalog + personal library
Institutional	Higher	Full API access
