# Authentication

All endpoints require these parameters:

{% code lineNumbers="true" %}

```typescript
if(!signatureResp){
                  toast.error('Please try again');
                  return;
                }
{  "userAuthPayload": signatureResp.data,
  "prompt": "Your prompt",
  "nftId": "YourNFTId"
}
```

{% endcode %}
