The Yahoo Finance API Alternative
There is no official Yahoo Finance API — the scraped endpoints break, rate-limit, and change without notice. Eulerpool is the documented, stable, free-tier replacement.

Why you're here
Libraries like yfinance hit undocumented endpoints on query1.finance.yahoo.com that Yahoo never supported for programmatic use. They break on every change, throttle aggressively, and the CSV download endpoint was removed years ago. This guide maps each one to a stable Eulerpool method.
Endpoint migration map
| Yahoo Finance endpoint / yfinance | Eulerpool equivalent |
|---|---|
| v7/finance/quote | client.equity.quotes(isin) |
| v8/finance/chart/{sym} | client.equity.candles(isin) |
| v10/finance/quoteSummary (financials) | client.equity.incomeStatement(isin) · balanceSheet · cashFlowStatement |
| quoteSummary (assetProfile) | client.equity.profile(isin) |
| quoteSummary (defaultKeyStatistics) | client.equity.metrics(isin) |
| yf.Ticker().dividends | client.equity.dividends(isin) |
| yf.Ticker().news | client.news.byIsin(isin) |
| yf.Ticker().major_holders | client.equity.ownership(isin) |
| v7/finance/download (removed) | client.equity.candles(isin) |
Yahoo uses ticker symbols; Eulerpool uses ISINs. Resolve any ticker with client.equity.search("AAPL").
Before & after
import yfinance as yf
# undocumented, rate-limited, breaks on change
data = yf.Ticker("AAPL").income_stmtimport eulerpool
client = eulerpool.Eulerpool("YOUR_API_KEY")
data = client.equity.income_statement("US0378331005")What you gain by switching
