# API key providers

> Connect provider API keys for OpenAI, Anthropic, Google, xAI, DeepSeek, Mistral, Groq, Cerebras, AWS Bedrock, NVIDIA NIM, OpenRouter, Hugging Face, and more.

Most providers work the standard way: sign up, generate an API key, paste it into the gateway. Routed requests go out with that key as the credential.

## Supported providers

New providers are added often, so **Providers → Usage-based** in the dashboard always shows the current list.

### Gemini Free

Gemini Free is a managed tile. The gateway provisions the credential automatically, so there's no key to fetch from Google first: add the tile and you have a free model to route to. It behaves like any other provider once connected.

<Note>
  BytePlus, NousResearch, Command Code, ClinePass, Kiro, GitHub Copilot, Ollama
  Cloud, and OpenCode Go connect through a plan rather than an API key, so they
  have no API Keys tab. See
  [Subscription-based providers](/llm-gateway/docs/llm-gateway/docs/providers/subscription-based-providers).
</Note>

## Add a provider

<Steps>
  <Step title="Open the Usage-based page">
    In the dashboard sidebar, open **Providers → Usage-based**. Under
    **Supported usage-based providers** you get a card per provider.
  </Step>

  <Step title="Click Connect on the provider">
    **Connect** opens a panel where you paste your API key.
  </Step>

  <Step title="Paste the key and save">
    The gateway validates the key by fetching the provider's model list. That list
    is what routing sees until you refresh it. If the key is rejected,
    double-check the prefix below.
  </Step>
</Steps>

</Frame>

## Refreshing the model list

A connection keeps the model list it discovered when you saved it. Nothing re-checks it on a schedule. When a provider adds, renames, or drops a model, click **Refresh models**: on your harness's **Routing** page, or on the connection itself under **Providers**.

The refresh replaces the list, it does not merge it. A tier or a fallback pinned to a model id that no longer exists stops matching, so pin it to one of the new ids.

## Key prefixes

Each provider issues keys with a recognizable prefix. Useful for catching paste mistakes:

| Provider     | Prefix    | Example      |
| ------------ | --------- | ------------ |
| OpenAI       | `sk-`     | `sk-...`     |
| Anthropic    | `sk-ant-` | `sk-ant-...` |
| xAI          | `xai-`    | `xai-...`    |
| Meta         | `LLM_`    | `LLM_...`    |
| DeepSeek     | `sk-`     | `sk-...`     |
| Moonshot     | `sk-`     | `sk-...`     |
| MiniMax      | `sk-`     | `sk-...`     |
| Qwen         | `sk-`     | `sk-...`     |
| OpenRouter   | `sk-or-`  | `sk-or-...`  |
| Google       | none      | API key      |
| Mistral      | none      | API key      |
| Z.ai         | none      | API key      |
| Fireworks    | `fw_`     | `fw_...`     |
| Groq         | `gsk_`    | `gsk_...`    |
| Pioneer      | `pio_sk_` | `pio_sk_...` |
| Xiaomi MiMo  | `sk-`     | `sk-...`     |
| Hugging Face | `hf_`     | `hf_...`     |

Providers not listed here (Cerebras, NVIDIA NIM, AWS Bedrock, Kilo, OpenCode Zen) issue keys with no fixed prefix.

## Regional providers

Some providers serve more than one region. Alibaba Cloud, AWS Bedrock, and MiniMax let you pick a region when you connect them, and the gateway routes to the matching endpoint.
