# Batch

> Submit, list, poll, and delete asynchronous batches of inference requests. See https://openrouter.ai/docs/batch-quickstart.

## Overview

Submit, list, poll, and delete asynchronous batches of inference requests. See [https://openrouter.ai/docs/batch-quickstart](https://openrouter.ai/docs/batch-quickstart.md).

### Available Operations

* [List](#list) - List batches
* [CreateBatches](#createbatches) - Create a batch
* [Delete](#delete) - Delete a batch
* [GetBatches](#getbatches) - Get a batch

## List

Lists batches in the workspace of the authenticating API key, newest first. To fetch the next page, pass the previous page's `last_id` as `after`. List items omit `results`. Use `GET /batches/{id}` to get them. See the [Batch API Quickstart](https://openrouter.ai/docs/batch-quickstart.md).

### Example Usage

```go theme={null}
package main

import(
	"context"
	"os"
	openrouter "github.com/OpenRouterTeam/go-sdk"
	"log"
)

func main() {
    ctx := context.Background()

    s := openrouter.New(
        openrouter.WithSecurity(os.Getenv("OPENROUTER_API_KEY")),
    )

    res, err := s.Batch.List(ctx, nil)
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        for {
            // handle items

            res, err = res.Next()

            if err != nil {
                // handle error
            }

            if res == nil {
                break
            }
        }
    }
}
```

## CreateBatches

Creates a batch of requests that run asynchronously against a single endpoint (`/v1/chat/completions`, `/v1/responses`, `/v1/messages`, `/v1/embeddings`). Returns `202` with `status: "validating"`. Poll `GET /batches/{id}` for progress and results. See the [Batch API Quickstart](https://openrouter.ai/docs/batch-quickstart.md).

### Example Usage: chatCompletions

package main

import(
	"context"
	"os"

	"github.com/OpenRouterTeam/go-sdk/models/components"
	"log"
)

func main() {
    ctx := context.Background()

    s := openrouter.New(
        openrouter.WithSecurity(os.Getenv("OPENROUTER_API_KEY")),
    )

    res, err := s.Batch.CreateBatches(ctx, components.BatchSubmitBody{
        Endpoint: components.EndpointRootV1ChatCompletions,
        Model: "openai/gpt-4o",
        Requests: []components.Request{
            components.Request{
                Body: map[string]any{
                    "messages": []any{
                        map[string]any{
