    Make Your First API Call

    To initiate your first API call to the Prodia API, adhere to the following steps:

    1. Create a Prodia Account: If you lack an account, visit app.prodia.com and select Sign Up. Ensure you possess a Pro subscription to generate a v2 token.

    2. Generate Your API Token: Access the API Dashboard to create a token. Assign it a meaningful label, such as 'getting started'. Securely copy the API Key, as it will only be displayed once.

    3. Construct the API Request: Utilize the appropriate endpoint for your intended action. For instance, to generate images, employ the /inference endpoint.

    4. Set Up the Request Headers: Incorporate your API key in the headers for authentication. For example:

      headers = {
          'Authorization': 'Bearer YOUR_API_KEY',
          'Content-Type': 'application/json'
      }
      
      
    5. Prepare the Request Body: Format the data you intend to send in JSON. For example:

      data = {
          'prompt': 'puppies in a cloud',
          'max_tokens': 50
      }
      
      
    6. Send the Request: Utilize your preferred library to dispatch the request. In Python, it may appear as follows:

      response = requests.post('https://inference.prodia.com/v2/job', headers=headers, json=data)
      
      
    7. Handle the Response: Examine the response status and parse the returned data. Upon success, you should receive a JSON object containing the generated image. For example:

      if response.status_code == 200:
          result = response.json()
          print('Image generated successfully:', result)
      else:
          print('Error:', response.status_code)
