API2D

All software, websites, and SDKs that use the OpenAI interface and support setting custom API domains/addresses can use API2D. You can find usage tutorials for dozens of applications on the 'Compatible Applications' page in the left menu after logging in.

API2D uses points (P) for billing, with the overall price maintained at 1.5 times the official price of the interface provider (except for the 3.5 yuan recharge tier). For example, 1P = 133.3 GPT-3.5 (non-16k, non-1106) input tokens. You can use the point calculator to calculate the cost.

API2D supports most OpenAI interfaces, Claude, Stability, vector databases, and AzureTTS. You can learn more details by reading the API documentation.

API2D supports WeChat, Alipay, and China bank card payments, as well as credit card payments through Stripe.

ChatGPT is a user-facing website provided by OpenAI. Its GPT4 is not a single model but a product pre-configured with prompts and packaged with tools. The official OpenAI API provides simpler and more singular functionality, requiring users/clients to add retrieval enhancement and tool usage functions themselves. API2D's interface is strictly consistent with the official OpenAI API, so it does not directly support additional functions. However, you can add document retrieval enhancement and search enhancement functions through ForwardKey settings and grouping settings in the agent function.

Because the GPT-4 opened to API calls by OpenAI has training data from before September 2021. If the model is not retrained after training, it will not automatically update the knowledge inside.

The point validity period is half a year (180 days) after the last recharge. That is, if it is about to expire, you only need to recharge a few yuan to extend the validity period by 180 days. Expired points will not be cleared in real-time but will be processed during system upgrades or maintenance (which has not happened yet). If you find that the points have expired and have not been cleared, you can immediately recharge a small amount to extend the validity period.

After successful payment, the points should arrive without significant delay. If you still cannot refresh the points after waiting a few minutes (click the refresh icon after the points in the upper right corner), you can directly contact customer service (WeChat lj925184928, email admin@api2d.com) or provide feedback in our WeChat or Telegram group, and we will deal with it as soon as possible.
