Installation

go get github.com/scalar/galaxy-go

Usage

package main

import (
	"context"
	"fmt"
	"os"

	sdk "github.com/scalar/galaxy-go"
	"github.com/scalar/galaxy-go/option"
)

func main() {
	client := sdk.NewClient(
		option.WithBearerAuth(os.Getenv("BEARER_AUTH")),
	)

	planet, err := client.Planets.ListAllData(context.Background(), sdk.PlanetListAllDataParams{
		Limit:  sdk.F[int64](10),
		Offset: sdk.F[int64](0),
	})
	if err != nil {
		panic(err)
	}

	fmt.Println(planet)
}

The examples in the following sections assume a client configured as shown above.

See the API reference for every available operation.

Authentication

Pass credentials to the generated client constructor. Environment variables are read automatically when supported by the target runtime.

Option	Type	Default	Description
option.WithBearerAuth	string | provider	-	JWT Bearer token authentication Defaults to BEARER_AUTH.
option.WithBasicAuthUsername	string | provider	-	Credential for the basicAuth_username client option. Defaults to BASIC_AUTH_USERNAME.
option.WithBasicAuthPassword	string | provider	-	Credential for the basicAuth_password client option. Defaults to BASIC_AUTH_PASSWORD.
option.WithAPIKeyHeader	string | provider	-	API key request header Defaults to API_KEY_HEADER.
option.WithAPIKeyQuery	string | provider	-	API key query parameter Defaults to API_KEY_QUERY.
option.WithAPIKeyCookie	string | provider	-	API key browser cookie Defaults to API_KEY_COOKIE.

Declared schemes:

• bearerAuth bearer token
• basicAuth basic authentication
• apiKeyHeader API key in header X-API-Key
• apiKeyQuery API key in query api_key
• apiKeyCookie API key in cookie api_key
• oAuth2 OAuth2/OpenID Connect
• openIdConnect OAuth2/OpenID Connect

Errors

Non-success responses return generated API errors. Error objects expose status, headers, response body, and request metadata where the target runtime supports it.

planet, err := client.Planets.ListAllData(context.Background(), sdk.PlanetListAllDataParams{
if err != nil {
	var apiErr *sdk.Error
	if errors.As(err, &apiErr) {
		fmt.Println(apiErr.StatusCode, apiErr.RawJSON())
	}
	panic(err)
}

// imports: sdk "github.com/scalar/galaxy-go", "errors", "fmt"

Documented error statuses: 400, 401, 403, 404, 409, 422, 429.

Client Options

Configure the generated client by setting any of these options when you create it.

client := sdk.NewClient(
	option.WithBaseURL("https://api.example.com"),
	option.WithMaxRetries(2),
	option.WithRequestTimeout(60*time.Second),
)

// imports: sdk "github.com/scalar/galaxy-go", "github.com/scalar/galaxy-go/option", "time"

Option	Type	Default	Description
option.WithBearerAuth	func(string) option.RequestOption	os.Getenv("BEARER_AUTH")	JWT Bearer token authentication
option.WithBasicAuthUsername	func(string) option.RequestOption	os.Getenv("BASIC_AUTH_USERNAME")	Credential for the basicAuth_username client option.
option.WithBasicAuthPassword	func(string) option.RequestOption	os.Getenv("BASIC_AUTH_PASSWORD")	Credential for the basicAuth_password client option.
option.WithAPIKeyHeader	func(string) option.RequestOption	os.Getenv("API_KEY_HEADER")	API key request header
option.WithAPIKeyQuery	func(string) option.RequestOption	os.Getenv("API_KEY_QUERY")	API key query parameter
option.WithAPIKeyCookie	func(string) option.RequestOption	os.Getenv("API_KEY_COOKIE")	API key browser cookie
option.WithEnvironmentProduction	func() option.RequestOption	-	Select the production API environment.
option.WithEnvironmentRespondsWithYourRequestData	func() option.RequestOption	-	Select the responds_with_your_request_data API environment.
option.WithBaseURL	func(string) option.RequestOption	os.Getenv("SCALAR_BASE_URL")	Override the default API base URL.
option.WithRequestTimeout	func(time.Duration) option.RequestOption	-	Maximum time to wait for each request attempt.
option.WithMaxRetries	func(int) option.RequestOption	2	Number of retries for temporary failures.
option.WithHTTPClient	func(option.HTTPClient) option.RequestOption	-	Custom HTTP client or transport implementation.

Request Options

Option	Type	Default	Description
option.WithHeader	func(string, string) option.RequestOption	-	Set a per-request header.
option.WithQuery	func(string, string) option.RequestOption	-	Set a per-request query parameter.
option.WithRequestBody	func(string, any) option.RequestOption	-	Override the serialized request body and content type.
option.WithResponseInto	func(**http.Response) option.RequestOption	-	Capture the raw HTTP response.
option.WithResponseBodyInto	func(any) option.RequestOption	-	Override the response deserialization target.

Retries and Timeouts

Generated clients support request timeouts and retry temporary failures such as network errors, 408, 409, 429, and 5xx responses. Retry delays honor Retry-After headers when present. Tune the retry and timeout client options shown above, or override them per request.

Helpers

• Pass option.WithResponseInto(&raw) to capture the underlying *http.Response for a request.
• Use the generated String, Int, Bool, Float, Time, Opt, and Ptr helpers when setting optional params.

Logging

• Wrap the HTTP client with option.WithMiddleware(...) to add request logging or tracing.

Requirements

• Go 1.22 or newer
