Install

go get github.com/eulerpool/eulerpool-go

Quick start — Go stock API

package main

import (
	"context"
	"encoding/json"
	"fmt"
	"log"

	eulerpool "github.com/eulerpool/eulerpool-go"
)

func main() {
	client := eulerpool.NewClient("YOUR_API_KEY")
	ctx := context.Background()

	profile, err := client.Equity.Profile(ctx, "US0378331005")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(string(profile))

	income, err := client.Equity.IncomeStatement(ctx, "AAPL")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(string(income))

	holdings, err := client.Etf.Holdings(ctx, "IE00B4L5Y983")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(string(holdings))

	var result map[string]interface{}
	json.Unmarshal(profile, &result)
	fmt.Printf("Company: %s\n", result["name"])
}

Authentication

Pass your API key when creating the client. By default it is sent as ?token=. To use Authorization: Bearer:

client := eulerpool.NewClient("YOUR_API_KEY", &eulerpool.ClientOptions{
	UseAuthHeader: true,
})

Get your free API key at eulerpool.com/developers/register.

Streaming

The tick plant is consumed over SSE (GET /market/stream) from Go — no extra dependency:

ticks, errs := client.Stream.Subscribe(ctx, []string{"AAPL"}, []string{"T", "Q"})
for tick := range ticks {
    fmt.Println(tick.Ev, tick.Ticker, tick.Price)
}

Channels: T trades, Q quotes, A 1-second bars, L2 book. WebSocket (wss://api.eulerpool.com/v1/subscribe) is the same plant; see Streaming docs.

client := eulerpool.NewClient("YOUR_API_KEY", &eulerpool.ClientOptions{
	BaseURL:       "https://api.eulerpool.com/api/1",
	UseAuthHeader: false,
	MaxRetries:    2,
	Timeout:       30 * time.Second,
})

Complete API catalog — all 53 resources, all 418 endpoints

Typed Go services ship for the core surface (Equity, Etf, Macro, Forex, Bonds, Crypto, Market, …). The table lists every Eulerpool REST endpoint — same catalog as Python and JavaScript — so Go, Node, and Python share one financial data API.

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.
