import pandas as pd

client = eulerpool.Client("ep_live_xxx")
df = client.equity.fundamentals(
    "AAPL", as_of="2020-01-15"
)
print(df.head())
R
library(eulerpool)

client <- eulerpool_client("ep_live_xxx")

)
head(fundamentals)

Frequently asked questions

Yes. Eulerpool provides point-in-time, survivorship-bias-free data that meets academic research standards. 100+ years of historical data, delisted companies included, and GAAP/IFRS-normalized fundamentals make it suitable for published research and dissertations.

Yes — academics get Eulerpool free. The free tier (100,000 calls/month) covers most projects, and students, PhD candidates, and researchers get the Startup tier (10,000,000 calls/month) at no cost: email michael@eulerpool.com from your university address with one line about your research. Institutional agreements are available for entire departments or research groups.

Yes. Eulerpool data can be cited in academic publications. We provide data provenance documentation and methodology descriptions suitable for peer review. Many published papers in finance and economics use Eulerpool as a data source.

Yes. Point-in-time financial statements, survivorship-bias-free price data, and pre-calculated ratios (P/E, P/B, ROE) enable factor research. The Python SDK integrates with pandas, numpy, and common backtesting frameworks for quantitative analysis.

Eulerpool provides similar data coverage to CRSP (prices) and Compustat (fundamentals) via a modern REST API. Key advantages include global coverage (not US-only), real-time data, point-in-time storage, and a free tier. The API format makes it easier to integrate into modern research workflows.
