  <Accordion title="How do I call the API?">
    The Runcrate Models API is **OpenAI-compatible**. Point your existing OpenAI SDK or HTTP client to `https://api.runcrate.ai/v1` and use your Runcrate API key. See the [Quickstart](/getting-started/quickstart) for examples.
  </Accordion>

  <Accordion title="Can I use the OpenAI SDK?">
    Yes. Both the Python and JavaScript OpenAI SDKs work with Runcrate. Just change the `base_url` (Python) or `baseURL` (JavaScript) to `https://api.runcrate.ai/v1` and use your Runcrate API key.

    ```python theme={"theme":"github-dark"}
    from openai import OpenAI

    client = OpenAI(
        base_url="https://api.runcrate.ai/v1",
        api_key="rc_live_YOUR_API_KEY",
    )
    ```

  <Accordion title="Is streaming supported?">
    Yes. Streaming is supported for all chat completion models. Set `stream: true` in your request to receive responses as server-sent events.
  </Accordion>

  <Accordion title="How is model usage billed?">
    * **Text models** (chat, code, reasoning) — billed per token (input + output)
    * **Image generation** — billed per image
    * **Video generation** — billed per video
    * **Text-to-speech** — billed per generation
    * **Speech-to-text** — billed per audio minute

    Rates vary by model. Check the [Model Catalog](/models/model-catalog) or [Pricing](/billing/pricing) page.
  </Accordion>

  <Accordion title="What is the Playground?">
    The Playground is a web-based interface in the dashboard where you can test any model interactively without writing code. Go to **Dashboard → Playground** to try it. It uses your workspace's default API key.
  </Accordion>

  <Accordion title="Are there rate limits?">
    Yes, rate limits apply to prevent abuse. Limits vary by model and account. If you hit a rate limit, you will receive a `429 Too Many Requests` response. Wait briefly and retry.
  </Accordion>

  <Accordion title="How do I check model pricing?">
    Go to the [Model Catalog](/models/model-catalog) in the dashboard or the [Pricing](/billing/pricing) page in the docs. Each model shows its per-token or per-generation rate.
