# Get started with the Trassets Data API

> Learn how to request an API key and make your first call to the Trassets Data API in three steps.

This guide gets you from zero to a successful API call in a few minutes. You need a Unix-like shell with curl installed.

<Steps>
  <Step title="Request an API key">
    Visit [portal.api.trassets.ai](https://portal.api.trassets.ai) and create an account. Generate an API key and store it securely. The plaintext key is shown only once.
  </Step>

  <Step title="Make your first request">
    Set your key as an environment variable and query the real-estate objects endpoint with a small page size.

    ```bash theme={null}
    export TRASSETS_API_KEY="sk_live_…"
    curl "https://api.trassets.ai/property/properties?limit=1" \
      -H "X-API-Key: $TRASSETS_API_KEY"
    ```

    The API returns a JSON array of objects. A typical response looks like this:

    ```json theme={null}
    [
      {
        "property_id": 42,
        "obj_name": "Musterstrasse 12",
        "entrance_1": "Musterstrasse 12",
        "postcode": "10115",
        "city": "Berlin"
      }
    ]
    ```

    <Note>
      The exact set of fields depends on your customer schema — columns are read
      dynamically from your database. See the [Field Glossary](/data-model/field-glossary)
      for fields that appear across multiple endpoints.
    </Note>

    Success! You have authenticated and fetched your first row of real-estate data.

  <Step title="Next steps">
    * Read [Authentication](/authentication) for key management and access tiers.
    * Explore [Endpoint Types](/concepts/endpoint-types) to learn when to use category endpoints versus raw endpoints.
    * Browse the [API Reference Overview](/api-reference/introduction) for the full endpoint list.
