Why Choose an Uncensored API?

Most consumer chatbots apply strict safety filters that break character or refuse lawful adult content. Our uncensored llm api serves an open-weight model tuned to answer without those refusals, making it ideal for developers building NSFW chat applications or games. We do not hide behind marketing fluff; we provide a raw, developer-grade endpoint. The model handles controversial, sexual, or political topics freely, ensuring your application’s logic isn’t disrupted by external moderation layers. While we block sexual content involving minors, everything else is fair game. This approach gives you full control over the user experience, whether you are building a roleplay bot or an adult-themed content generator.

OpenAI Compatible & Easy to Integrate

Integration is straightforward because we use the standard OpenAI chat-completions format. You simply point your client to https://api.nsfwchat.top/v1 and use your API key. We support streaming via SSE, function calling, and JSON mode, along with standard parameters like temperature and top_p. This means you can use the same SDKs you already know. We do not offer embeddings, images, or audio; this is a text-only API focused on high-quality language generation. If you need other modalities, you can route those separately while using our API for the core text interactions.

curl https://api.nsfwchat.top/v1/chat/completions \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "uncensored",
    "messages": [{"role": "user", "content": "Write a blunt product review of a cheap VPN."}]
  }'

Transparent Prepaid Token Pricing

Our pricing is simple and transparent: $0.25 per 1M input tokens and $1.00 per 1M output tokens. You pay only for real token usage; errors and refusals are free. There are no monthly fees, no subscriptions, and no surprise costs. Your prepaid credit never expires, giving you flexibility to use it whenever you need it. This model is particularly cost-effective for developers who want to control exactly what they pay for, without locking into a tiered plan that may include unused features.

Crypto Payments & Instant Activation

We accept crypto payments only: USDT (TRC20) or USDC (Base). Top-ups range from $10 to $500, with bonus credit for larger amounts. Sign up with Google or email to get your key instantly. No card is needed for the trial, which gives every new account $0.50 valid for 7 days. This setup ensures fast, borderless payments without the hassle of bank transfers or invoices. If you make a mistake, such as a double charge, we fix it via Support. Credit is not refunded, but it never expires.

Who This Is NOT For

If you need image generation, audio, or embeddings, this API is not for you. We do not offer model routing between multiple vendors, nor do we provide SLA guarantees or SOC2 certifications. We are not a consumer chatbot; we are a raw API for developers. If you require a dedicated team, on-prem deployment, or a specific named customer benchmark, look elsewhere. This service is for developers who want a simple, uncensored text API with transparent pricing and no marketing overhead.
