#include "eulerpool/eulerpool.hpp"
#include <iostream>

int main() {
    eulerpool::Eulerpool client(std::getenv("EULERPOOL_API_KEY"));
    std::cout << client.equity.profile("AAPL") << std::endl;
}

std::getenv may return nullptr; the const char* constructor treats that as “read EULERPOOL_API_KEY”.

Quick start — C++ stock API

#include "eulerpool/eulerpool.hpp"
#include <iostream>

int main() {
    eulerpool::Eulerpool client(std::getenv("EULERPOOL_API_KEY"));

    auto profile = client.equity.profile("US0378331005");
    auto metrics = client.equity.metrics("AAPL");
    auto holdings = client.etf.holdings("IE00B4L5Y983");
    auto rates = client.forex.rates("EUR");
    auto cpi = client.macro.fredObservations("CPIAUCSL");

    std::cout << profile << std::endl;
}

Parse with nlohmann/json:

auto j = nlohmann::json::parse(client.equity.metrics("AAPL"));
std::cout << j["valuation"]["pe"] << std::endl;

Complete API catalog — all 53 resources, all 418 endpoints

Same catalog as Python. Method names are camelCase (incomeStatement, fredObservations).

Official accessors: 53 resources, 418 methods, generated from the public OpenAPI spec. Any path also works via the escape hatch. Identifiers: ticker or ISIN.

Equities — stock API, fundamentals, quotes, insider trades

Company profiles, stock quotes, OHLCV candles, income statements, balance sheets, cash flow, ratios, estimates, dividends, splits, insider trades (US Form 4 and EU), short interest, ESG, SWOT, peers, segments, employees, market cap, shares outstanding, price targets, analyst grades, AAQS quality scores, and ETF exposure. Tickers and ISINs both work.
