# Shared inference

> Send requests to Morph models without provisioning an endpoint

Call shared models immediately without reserving GPUs. Morph manages the pools and bills usage at each model's token rates.

## Send your first request

Create a [dashboard API key](https://www.morphllm.com/dashboard/api-keys). To bill an organization, select it before creating the key.

Set your terminal's key:

```bash theme={null}
export MORPH_API_KEY="YOUR_MORPH_API_KEY"
```

These examples use `morph-glm53-744b`. The [catalog](/sdk/components/fast-models) lists public model IDs, context windows, and rates.

  <Tab title="cURL">
    ```bash theme={null}
    curl --fail-with-body https://api.morphllm.com/v1/chat/completions \
      -H "Authorization: Bearer $MORPH_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{
        "model": "morph-glm53-744b",
        "messages": [{"role": "user", "content": "Write a Python function that checks whether a string is a palindrome."}]
      }'
    ```
  </Tab>

  <Tab title="Python">
    Run `pip install openai`, then:

    ```python theme={null}
    import os
    from openai import OpenAI

    client = OpenAI(
        api_key=os.environ["MORPH_API_KEY"],
        base_url="https://api.morphllm.com/v1",
    )

    response = client.chat.completions.create(
        model="morph-glm53-744b",
        messages=[{"role": "user", "content": "Write a Python function that checks whether a string is a palindrome."}],
    )
    print(response.choices[0].message.content)
    ```
  </Tab>

  <Tab title="JavaScript">
    Run `npm install openai`. Save as `request.mjs`; run `node request.mjs`:

    ```javascript theme={null}
    import OpenAI from "openai";

    const client = new OpenAI({
      apiKey: process.env.MORPH_API_KEY,
      baseURL: "https://api.morphllm.com/v1",
    });

    const response = await client.chat.completions.create({
      model: "morph-glm53-744b",
      messages: [{ role: "user", content: "Write a Python function that checks whether a string is a palindrome." }],
    });
    console.log(response.choices[0].message.content);
    ```
  </Tab>
</Tabs>

Keep keys on your server, never in browser code.

## Use your existing client

OpenAI clients need `https://api.morphllm.com/v1`, your Morph key, and a public model ID.

See [Anthropic formats](/endpoints#api-formats) and [coding agent setup](/guides/coding-agents) for other clients.

## Handle busy periods and errors

For `429`, honor `Retry-After` when present; retry with exponential backoff and jitter. Immediate retries add load, not capacity.

For `401`, check the key and authorization header. For model errors, check the catalog ID. Correct invalid credentials or IDs before retrying.

[Standby](/sdk/components/standby) is a separate tier for work that tolerates capacity rejections; [batch processing](/sdk/components/batch) handles work without interactive responses.

## Monitor usage and choose capacity

The [dashboard](https://www.morphllm.com/dashboard) shows requests, usage, and billing for your key's account. See [prompt caching](/sdk/components/caching) for repeated input.

For reserved capacity, review [dedicated plans and cancellation](/dedicated-endpoints) before purchasing. Idle capacity remains billable.
