papers-openalex

[!WARNING] Internal crate for papers. API may change without notice.

Async Rust client for the OpenAlex REST API. Covers 240M+ works, 110M+ authors, and metadata across sources, institutions, topics, publishers, and funders.

Quick start

use papers_openalex::{OpenAlexClient, ListParams};

let client = OpenAlexClient::new();

let params = ListParams::builder()
    .search("machine learning")
    .per_page(5)
    .build();
let response = client.list_works(&params).await?;

Authentication

Optional for most endpoints. Set OPENALEX_KEY or pass it explicitly:

let client = OpenAlexClient::new();                    // reads OPENALEX_KEY from env
let client = OpenAlexClient::with_api_key("your-key"); // explicit

API coverage

Plus find_works for AI semantic search (requires API key, 1,000 credits per call).
