If you don't specify a base URL, this is the endpoint used by default. ## EU Data Residency The EU endpoint (`llm-gateway.eu.assemblyai.com`) guarantees your data never leaves the European Union. This is designed for organizations with strict data residency and governance requirements—your request and response data will remain entirely within the EU. ## Endpoints | Endpoint | Base URL | Description | | ------------ | ----------------------------------------------------------- | -------------------- | | US (default) | `https://llm-gateway.assemblyai.com/v1/chat/completions` | Data stays in the US | | EU | `https://llm-gateway.eu.assemblyai.com/v1/chat/completions` | Data stays in the EU | Effective July 1, 2026, in-region LLM Gateway requests will increase by 10% as a direct pass-through of provider price increases, with no AssemblyAI upcharge. Opt into [global routing](#global-routing) to keep current pricing. ## EU model availability The EU endpoint currently supports Anthropic Claude and Google Gemini models. OpenAI models are only available through the US endpoint. | Provider | US | EU | | ------------------ | --- | --- | | Anthropic Claude | Yes | Yes | | Google Gemini | Yes | Yes | | OpenAI GPT | Yes | No | | Alibaba Cloud Qwen | Yes | No | | Moonshot AI Kimi | Yes | No | For a full list of available models, see the [LLM Gateway Overview](/llm-gateway/quickstart). ## Which endpoint should I use? * **No data residency requirements?** Use the **default endpoint**. No configuration change is needed. * **Need EU data residency?** Use the **EU endpoint** to ensure your data stays within the European Union. Note that only Claude and Gemini models are available in the EU region. * **No data residency, compliance, or latency needs, and want cheaper calls?** Opt into [**global routing**](#global-routing) on top of the default endpoint to route requests to the provider's global endpoints at lower cost. ## How to use it Update your request URL to your preferred endpoint. Select an endpoint tab below to see examples for each. The US endpoint is the default. No configuration change is required. ```python title="Python" expandable theme={null} import requests headers = { "authorization": "" } # No URL change needed — US is the default response = requests.post( "https://llm-gateway.assemblyai.com/v1/chat/completions", headers=headers, json={ "model": "claude-sonnet-4-6", "messages": [ {"role": "user", "content": "What is the capital of France?"} ], "max_tokens": 1000 } ) result = response.json() print(result["choices"][0]["message"]["content"]) ``` ```javascript title="JavaScript" theme={null} // No URL change needed — US is the default const response = await fetch( "https://llm-gateway.assemblyai.com/v1/chat/completions", { method: "POST", headers: { authorization: "", "content-type": "application/json", }, body: JSON.stringify({ model: "claude-sonnet-4-6", messages: [{ role: "user", content: "What is the capital of France?" }], max_tokens: 1000, }), } ); const result = await response.json(); console.log(result.choices[0].message.content); ``` ```bash title="cURL" theme={null} curl -X POST \ "https://llm-gateway.assemblyai.com/v1/chat/completions" \ -H "Authorization: " \ -H "Content-Type: application/json" \ -d '{ "model": "claude-sonnet-4-6", "messages": [ { "role": "user", "content": "What is the capital of France?" } ], "max_tokens": 1000 }' ``` Use the EU endpoint to keep your data within the European Union. ```python title="Python" highlight={9} theme={null} import requests headers = { "authorization": "" } response = requests.post( "https://llm-gateway.eu.assemblyai.com/v1/chat/completions", headers=headers, json={ "model": "claude-sonnet-4-6", "messages": [ {"role": "user", "content": "What is the capital of France?"} ], "max_tokens": 1000 } ) result = response.json() print(result["choices"][0]["message"]["content"]) ``` ```javascript title="JavaScript" highlight={3} theme={null} const response = await fetch( "https://llm-gateway.eu.assemblyai.com/v1/chat/completions", { method: "POST", headers: { authorization: "", "content-type": "application/json", }, body: JSON.stringify({ model: "claude-sonnet-4-6", messages: [{ role: "user", content: "What is the capital of France?" }], max_tokens: 1000, }), } ); const result = await response.json(); console.log(result.choices[0].message.content); ``` ```bash title="cURL" highlight={2} theme={null} curl -X POST \ "https://llm-gateway.eu.assemblyai.com/v1/chat/completions" \ -H "Authorization: " \ -H "Content-Type: application/json" \ -d '{ "model": "claude-sonnet-4-6", "messages": [ { "role": "user", "content": "What is the capital of France?" } ], "max_tokens": 1000 }' ``` ## Global routing Global routing is an opt-in option that routes your request to the provider's global (non-region) endpoints for lower-cost processing. Set `model_region` to `"global"` in your request body to enable it. Omit the parameter for default in-region processing. `"global"` is the only valid value for `model_region`. ### Who should use global routing? Global routing is designed for customers who: * Do **not** have data residency or compliance requirements that tie processing to a specific region. * Do **not** have strict latency requirements that depend on regional proximity. * Want lower-cost calls by using the provider's global endpoints. Global routing is always opt-in. If you don't set `model_region`, requests continue to be processed in-region (US or EU), so data residency and compliance remain the default behavior. If you have data residency, compliance, or latency needs, keep using the default in-region processing on the [US or EU endpoint](#endpoints). ### Availability Global routing is live for Anthropic Claude models. Support for Google Gemini 3 series models is coming soon. ### Usage tracking Global-routed usage appears as a new **Global** region in the spend and usage dashboard, separate from US and EU usage. ### How to use it Include `model_region: "global"` in your request body alongside `model` and `messages`. ```python title="Python" highlight={15} theme={null} import requests headers = { "authorization": "" } response = requests.post( "https://llm-gateway.assemblyai.com/v1/chat/completions", headers=headers, json={ "model": "claude-sonnet-4-6", "messages": [ {"role": "user", "content": "What is the capital of France?"} ], "model_region": "global", "max_tokens": 1000 } ) result = response.json() print(result["choices"][0]["message"]["content"]) ``` ```javascript title="JavaScript" highlight={12} theme={null} const response = await fetch( "https://llm-gateway.assemblyai.com/v1/chat/completions", { method: "POST", headers: { authorization: "", "content-type": "application/json", }, body: JSON.stringify({ model: "claude-sonnet-4-6", messages: [{ role: "user", content: "What is the capital of France?" }], model_region: "global", max_tokens: 1000, }), } ); const result = await response.json(); console.log(result.choices[0].message.content); ``` ```bash title="cURL" highlight={13} theme={null} curl -X POST \ "https://llm-gateway.assemblyai.com/v1/chat/completions" \ -H "Authorization: " \ -H "Content-Type: application/json" \ -d '{ "model": "claude-sonnet-4-6", "messages": [ { "role": "user", "content": "What is the capital of France?" } ], "model_region": "global", "max_tokens": 1000 }' ```
