# LLM Router and SDKs

> Connect an application to Edgee using an existing client, an Edgee SDK, or HTTP.

Use Edgee as an **LLM router** when your application sends model requests directly through an API client, an SDK, or HTTP. Configure a Gateway API key and a client, then inspect the resulting requests in the console.

If you want to run Claude Code, Codex, Cursor, or another coding assistant through Edgee, start with the [coding assistant quickstart](/docs/quickstart/index).

| Direct HTTP requests               | [First API request](/docs/llm-router/quickstart/api-key) and [Gateway API reference](/docs/llm-router/api-reference)                            |

## Send your first request

1. [Sign in to the console](https://www.edgee.ai/login), or accept your team’s invitation.
2. [Create a Gateway API key](/docs/llm-router/quickstart/api-key) and store it in your application's secret environment.
3. Choose a client above and configure the appropriate base URL. OpenAI clients usually use `https://edgee.io/v1`; follow the integration guide for your client.
4. Send a model request, then open **Logs** in the same organization to verify the key, served model, provider, and usage.

For the complete sequence, follow the [application quickstart](/docs/llm-router/quickstart).

## Configure application usage

| Task                                          | Guide                                                  |
| --------------------------------------------- | ------------------------------------------------------ |
| Restrict or rotate application credentials    | [Gateway API keys](/docs/llm-router/api-keys)               |
| Track tokens, costs, and request tags in code | [Application observability](/docs/llm-router/observability) |
| Use your own provider account                 | [BYOK](/docs/features/byok)                                 |
| Allow models and provider routes              | [Model access](/docs/features/model-access)                 |
| Configure routing and backups                 | [Retry and fallback](/docs/features/retry-and-fallback)     |
| Cap application spending                      | [Usage limits](/docs/features/usage-limits)                 |

Organization settings also apply to application traffic. Review inherited settings before changing an individual key.

## Gateway API versus Console API

The **Gateway API** serves model requests and uses Gateway API keys. The **Console API** manages organization resources and uses personal API tokens. To automate key management or export usage, use the separate [Console API](/docs/api-reference/console-api-setup) section.
