Go SDK - OpenModex

Installation

go get github.com/openmodexlabs/openmodex-sdk-go

Requires Go 1.21+.

Quick Start

package main

import (
    "context"
    "fmt"
    openmodex "github.com/openmodexlabs/openmodex-sdk-go"
)

func main() {
    client := openmodex.NewClient("omx_sk_YOUR_KEY")

    resp, err := client.Chat.Completions.Create(context.Background(), &openmodex.ChatCompletionParams{
        Model:    "gpt-4o",
        Messages: []openmodex.ChatMessage{
            {Role: "user", Content: "Hello!"},
        },
    })
    if err != nil {
        panic(err)
    }

    fmt.Println(resp.Choices[0].Message.Content)
}

Configuration

client := openmodex.NewClient("omx_sk_...",
    openmodex.WithBaseURL("https://api.openmodex.com/v1"),
    openmodex.WithTimeout(60 * time.Second),
    openmodex.WithMaxRetries(3),
    openmodex.WithFallbackModels("claude-3.5-sonnet", "gemini-2.0-flash"),
)

Streaming

stream, err := client.Chat.Completions.CreateStream(ctx, &openmodex.ChatCompletionParams{
    Model:    "gpt-4o",
    Messages: []openmodex.ChatMessage{
        {Role: "user", Content: "Write a poem."},
    },
})
if err != nil {
    panic(err)
}

for chunk, err := range stream.Iter() {
    if err != nil {
        break
    }
    fmt.Print(chunk.Choices[0].Delta.Content)
}

Model Aliases

The Go SDK supports convenient model aliases:

// Route to the cheapest available model
resp, _ := client.Chat.Completions.Create(ctx, &openmodex.ChatCompletionParams{
    Model: "@cheapest",
    Messages: messages,
})

// Other aliases: @auto, @fastest, @best

Presets

// Use built-in presets for common configurations
client := openmodex.NewClient("omx_sk_...", openmodex.CostSaver)
client := openmodex.NewClient("omx_sk_...", openmodex.LowLatency)
client := openmodex.NewClient("omx_sk_...", openmodex.HighQuality)
