What You Get With Your Key
Your API key grants access to the uncensored model via an OpenAI-compatible endpoint. This hosted service delivers text-in, text-out responses through POST /v1/chat/completions and supports streaming via SSE and tool/function calling. With a 100,000-token context window, you can handle long conversations or document processing without hitting limits quickly. The endpoint is accessible at https://api.characteraiapi.com/v1, ensuring you can use standard SDKs without complex configuration. Note that this service provides only chat completions; there are no embeddings, image, audio, or video generation capabilities included. Your prompts are not used for training, and the model remains uncensored for lawful adult content, excluding only sexual content involving minors.
Billing and Free Trial Details
Every new account receives $0.50 in trial credit, valid for 7 days. No credit card is required to activate this trial, making it easy to test the API's performance. When your trial credit expires or runs out, you can top up starting from $10 using crypto (USDT or USDC). Credits never expire, and you receive bonus credit: +5% for top-ups of $50 or more, and +10% for top-ups of $100 or more. Pricing is transparent at $0.25 per 1M input tokens and $1.00 per 1M output tokens. You can regenerate your API key at any time, which immediately revokes the old one, ensuring your access remains secure.
Questions and answers
Do I need a credit card to start?
No, you do not need a credit card to create an account or start your free trial. You only need to provide an email address and a password. Crypto (USDT or USDC) payment method is only required when you choose to top up your account with prepaid credit after the trial period.
What happens when my trial credit ends?
Your trial credit lasts for 7 days or until the $0.50 balance is exhausted, whichever comes first. Once the trial expires, you can top up your account with prepaid credit to continue using the API. Your prepaid credits never expire, so you can add funds whenever you are ready to resume usage.
How do I replace a leaked or compromised API key?
You can regenerate your API key at any time from your account settings. When you generate a new key, the previous one is immediately revoked and will no longer work. This ensures that if your key is exposed, you can secure your account by switching to a new key instantly.
Is the model uncensored for all topics?
The model does not refuse lawful adult, fictional, or controversial topics, making it ideal for creative writing and roleplay. However, there is one hard content limit: requests containing sexual content involving minors will always be blocked. All other lawful content remains accessible without additional filters.
