# 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

```go theme={null}
package main

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

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

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

    res, err := s.Classifications.GetTaskClassifications(ctx, operations.WindowSevend.ToPointer())
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        // handle response
    }
}
```
