What You Get with Your Key
Your API key grants access to a single, uncensored large language model served via an OpenAI-compatible interface. You can use standard libraries like the official OpenAI SDK or any compatible client by simply updating the base URL to https://api.deepseek4api.com/v1 and passing your key. The model supports streaming responses via Server-Sent Events and function calling, but does not offer embeddings, image generation, or fine-tuning. It is designed for high-context text generation with a 100,000 token window, making it suitable for long documents or complex conversational states. The model is not GPT, Claude, or DeepSeek; it is an independent open-weight model optimized for minimal refusals on lawful adult and controversial topics.
Billing and Trial Details
Every new account receives $0.50 in trial credit valid for 7 days, with no credit card required to activate it. Once the trial expires or is exhausted, you can add prepaid credit starting at $10 via crypto (USDT or USDC). Credits never expire, and you benefit from volume bonuses: +5% extra credit on $50 top-ups and +10% on $100 top-ups. The standard rate is $0.25 per 1M input tokens and $1.00 per 1M output tokens. There are no monthly subscriptions or hidden fees. Your account is limited to 300 requests per minute and an 8 MB request body, which is sufficient for most text-generation workflows.
Questions and answers
Do I need a credit card to get started?
No, you do not need a credit card or phone number to sign up and receive your API key. The trial credit of $0.50 is available immediately upon creating an account with just an email and password. You only need a payment method if you want to add prepaid credit after the trial period ends.
What happens when my trial credit runs out?
Your API key remains active, but you will need to add prepaid credit to continue making requests. You can top up from $10 using crypto (USDT or USDC). The prepaid credits never expire, so you can use them whenever you need without a recurring subscription fee.
How do I replace a leaked API key?
You can regenerate your API key at any time from your account dashboard. When you generate a new key, the previous one is immediately revoked, ensuring that anyone who had the old key can no longer use it. Each account is limited to one active key at a time.
Is this the official DeepSeek V4 API?
No, this is an independent service hosting an open-weight uncensored model. While our API endpoint is compatible with the standard OpenAI client format, the model itself is not DeepSeek V4, GPT, or any other vendor's model. It is a distinct model run on our own servers, designed to minimize content refusals for lawful use.
