API key¶

After you sign up for a Zyte API account, copy your API key.

It is recommended to configure your API key through an environment variable, so that it can be picked by both the command-line client and the Python client library:

On Windows:
```
> set ZYTE_API_KEY=YOUR_API_KEY
```
On macOS and Linux:
```
$ export ZYTE_API_KEY=YOUR_API_KEY
```

Alternatively, you may pass your API key to the clients directly:

To pass your API key directly to the command-line client, use the --api-key switch:
```
zyte-api --api-key YOUR_API_KEY …
```

To pass your API key directly to the Python client classes, use the api_key parameter when creating a client object:

from zyte_api import ZyteAPI

client = ZyteAPI(api_key="YOUR_API_KEY")

from zyte_api import AsyncZyteAPI

client = AsyncZyteAPI(api_key="YOUR_API_KEY")
