# Tools

> The catalog of server tools OpenRouter runs on behalf of a model: accepted `tools[].type` spellings per API format, engines and pricing, and which endpoints run each tool natively. See https://openrouter.ai/docs/guides/features/server-tools.

## Overview

The catalog of server tools OpenRouter runs on behalf of a model: accepted `tools[].type` spellings per API format, engines and pricing, and which endpoints run each tool natively. See [https://openrouter.ai/docs/guides/features/server-tools](https://openrouter.ai/docs/guides/features/server-tools).

### Available Operations

* [ListTools](#listtools) - List server tools
* [GetTool](#gettool) - Get a server tool

## ListTools

Lists every server tool OpenRouter can run on behalf of a model: accepted `tools[].type` spellings per API format, the engines behind it with their pricing, and how many endpoints run it natively.

### Example Usage

```go theme={null}
package main

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

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

    s := openrouter.New()

    res, err := s.Tools.ListTools(ctx, operations.ListToolsSecurity{
        Bearer: os.Getenv("OPENROUTER_BEARER"),
    }, optionalnullable.From(openrouter.Pointer[int64](0)), openrouter.Pointer[int64](50), nil)
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        // handle response
    }
}
```

### Parameters

| Parameter | Type | Required | Description | Example |

| `offset` | optionalnullable.OptionalNullable\[`int64`] | :heavy\_minus\_sign: | Number of records to skip for pagination. When both offset and limit are omitted, the full list is returned | 0 |
| `limit` | `*int64` | :heavy\_minus\_sign: | Maximum number of records to return (max 100). When both offset and limit are omitted, the full list is returned | 50 |
| `apiFormat` | [\*operations.APIFormat](../../models/operations/apiformat.mdx) | :heavy\_minus\_sign: | Only tools usable on this API format | responses |
| `opts` | \[][operations.Option](../../models/operations/option.mdx) | :heavy\_minus\_sign: | The options for this request. | |

## GetTool

One server tool by canonical name or any accepted alias, with the models that run it natively.

### Example Usage

	"log"
)

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

    s := openrouter.New()

    res, err := s.Tools.GetTool(ctx, operations.GetToolSecurity{
        Bearer: os.Getenv("OPENROUTER_BEARER"),
    }, "openrouter:web_search")
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        // handle response
    }
}
