# Classifications

> Task classification market-share endpoints

## Overview

Task classification market-share endpoints

### Available Operations

* [get\_task\_classifications](#get_task_classifications) - Task classification market share

## get\_task\_classifications

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

```python theme={null}
from openrouter import OpenRouter
import os


with OpenRouter(
    http_referer="<value>",
    x_open_router_title="<value>",
    x_open_router_categories="<value>",
    api_key=os.getenv("OPENROUTER_API_KEY", ""),
) as open_router:

    res = open_router.classifications.get_task_classifications(window="7d")

    # Handle response
    print(res)

```

### Parameters

| Parameter | Type | Required | Description | Example |
| - | - | - | - | - |
| `http_referer` | *Optional\[str]* | :heavy\_minus\_sign: | The app identifier should be your app's URL and is used as the primary identifier for rankings.<br />This is used to track API usage per application.<br /> | |
| `x_open_router_title` | *Optional\[str]* | :heavy\_minus\_sign: | The app display name allows you to customize how your app appears in OpenRouter's dashboard.<br /> | |
| `x_open_router_categories` | *Optional\[str]* | :heavy\_minus\_sign: | Comma-separated list of app categories (e.g. "cli-agent,cloud-agent"). Used for marketplace rankings.<br /> | |
| `window` | [Optional\[operations.Window\]](../../operations/window.mdx) | :heavy\_minus\_sign: | Trailing time window for the classification data. Currently only `7d` (trailing 7 days) is supported. | 7d |
| `retries` | [Optional\[utils.RetryConfig\]](../../models/utils/retryconfig.mdx) | :heavy\_minus\_sign: | Configuration to override the default retry behavior of the client. | |
