Comece pelo [guia REST](/docs/pt/api/rest) para criar token API. O exemplo usa a biblioteca padrão Python e não exige cliente gerado.

Salve como `example.py`:

```python
import json
import os
from urllib.parse import quote, urlencode
from urllib.request import Request, urlopen

base_url = os.getenv("CR_RECONSTRUCT_REST_URL", "https://reconstruct.dev/api/v1/platform")
token = os.environ["CR_RECONSTRUCT_API_TOKEN"]


def get_json(path):
    request = Request(
        f"{base_url.rstrip('/')}{path}",
        headers={"Authorization": f"Bearer {token}"},
    )
    with urlopen(request, timeout=10) as response:
        return json.load(response)


page = get_json("/catalogs?" + urlencode({"pageSize": 10}))
for catalog in page.get("catalogs", []):
    detail = get_json("/catalogs/" + quote(catalog["catalogId"], safe=""))
    print(detail["catalogId"], detail.get("description", ""))

if page.get("nextPageToken"):
    print("Next page token:", page["nextPageToken"])
```

Execute `python example.py`. Devolva `nextPageToken` como parâmetro `pageToken` para continuar a lista.
