Methods
The cost of using LLM Responses API endpoints depends on the selected method and priority of task execution. Available methods and priorities are described below.
DataForSEO has two main methods to deliver the results: Standard and Live.
If your system requires delivering instant results, the Live method is the best solution for you. Unlike the Standard method, this method doesn’t require making separate POST and GET requests to the corresponding endpoints.
If you don’t need to receive data in real-time, you can use the Standard method of data retrieval. This method requires making separate POST and GET requests, but it’s more affordable. Using this method, you can retrieve the results after our system collects them.
Alternatively, you can specify pingback_url or postback_url when setting a task, and we will notify you on completion of tasks or send them to you respectively.
If you need to set several tasks, you can receive the list of id for all completed tasks using ‘Tasks Ready’ endpoint, and then collect the results of each separate task using ‘Task GET’ endpoint.
ChatGPT and Claude in LLM Responses API support both Standard and Live methods:
• ChatGPT Live
• ChatGPT Task POST
• ChatGPT Tasks Ready
• ChatGPT Task GET
• Claude Live
• Claude Task POST
• Claude Tasks Ready
• Claude Task GET
Gemini and Perplexity in LLM Responses API support only the Live method of data retrieval:
• Gemini Live
• Perplexity Live
You can send up to 2000 API calls per minute. Contact us if you would like to raise the limit. Note that the maximum number of Live requests that can be sent simultaneously is limited to 30.
