# Classifications

> Task classification market-share endpoints

## Overview

Task classification market-share endpoints

### Available Operations

* [getTaskClassifications](#gettaskclassifications) - Task classification market share

## getTaskClassifications

Returns the market-share breakdown of OpenRouter traffic by task classification
(e.g. code generation, web search, summarization) over a trailing time window.

Each classification reports its share of classified sampled requests (`usage_share`)
and classified sampled token volume (`token_share`) as fractions between 0 and 1.
The unclassified `other` bucket is excluded. Absolute volumes are not exposed
because the underlying data is sampled.

Each classification also includes a `models` array listing the top models by
request volume within that classification, with their within-tag usage and token shares.

Classifications are grouped into macro-categories (Code, Data, Agent, General)
with aggregate shares provided for each.

Authenticate with any valid OpenRouter API key (same key used for inference).
Rate-limited to 30 requests/minute per key and 500 requests/day per account.

### 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.classifications.getTaskClassifications();

  console.log(result);
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript theme={null}
import { OpenRouterCore } from "@openrouter/sdk/core.js";
import { classificationsGetTaskClassifications } from "@openrouter/sdk/funcs/classificationsGetTaskClassifications.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 classificationsGetTaskClassifications(openRouter);
  if (res.ok) {
    const { value: result } = res;
    console.log(result);
  } else {
    console.log("classificationsGetTaskClassifications failed:", res.error);
  }
}

run();
```
