# Embeddings

> Text embedding endpoints

## Overview

Text embedding endpoints

### Available Operations

* [generate](#generate) - Submit an embedding request
* [listModels](#listmodels) - List all embeddings models

## generate

Submits an embedding request to the embeddings router

### Example Usage

```typescript theme={null}
import { OpenRouter } from "@openrouter/sdk";

const openRouter = new OpenRouter({
  httpReferer: "<value>",
  appTitle: "<value>",
  appCategories: "<value>",
  apiKey: process.env["OPENROUTER_API_KEY"] ?? "",
});

async function run() {
  const result = await openRouter.embeddings.generate({
    requestBody: {
      input: "The quick brown fox jumps over the lazy dog",
      model: "openai/text-embedding-3-small",
    },
  });

  console.log(result);
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript theme={null}
import { OpenRouterCore } from "@openrouter/sdk/core.js";
import { embeddingsGenerate } from "@openrouter/sdk/funcs/embeddingsGenerate.js";

// Use `OpenRouterCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const openRouter = new OpenRouterCore({
  httpReferer: "<value>",
  appTitle: "<value>",
  appCategories: "<value>",
  apiKey: process.env["OPENROUTER_API_KEY"] ?? "",
});

async function run() {
  const res = await embeddingsGenerate(openRouter, {
    requestBody: {
      input: "The quick brown fox jumps over the lazy dog",
      model: "openai/text-embedding-3-small",
    },
  });
  if (res.ok) {
    const { value: result } = res;
    console.log(result);
  } else {
    console.log("embeddingsGenerate failed:", res.error);
  }
}

run();
```
