What is the OpenRouter API?
The OpenRouter API acts as a unified gateway to multiple large language models. Instead of managing separate API keys for different providers, you send requests to a single endpoint. The service routes your prompt to the selected model and returns the completion. This abstraction simplifies integration for developers who want to experiment with different architectures.
However, this convenience comes with restrictions on free tiers. Users often encounter daily caps that reset after 24 hours. If your application sends more requests than allowed, you receive a 429 error. This behavior is designed to manage server load for free users.
Our service offers a different approach. We provide a direct, OpenAI-compatible endpoint for an uncensored model. You do not need to worry about daily quotas. Your code continues to run without hitting sudden limits. We focus on developer integration with prepaid crypto billing. This ensures your infrastructure remains stable during high-volume tasks.
Understanding openrouter limits
Daily request quotas are the primary constraint for free OpenRouter users. These limits vary by model, with some models restricted to just 50 requests per day. This restriction forces users to create multiple accounts to scale their usage. It also disrupts long-running scripts that exceed the daily allowance.
Our API removes these daily caps entirely. Instead, we enforce rate limits per minute. You get 300 requests per minute per key. This allows for burst traffic without waiting for the next day. Concurrency is limited to 8 simultaneous requests per key. Request bodies are capped at 8 MB. These limits are designed to prevent abuse while allowing serious development work.
The context window supports up to 100,000 tokens. This includes both the prompt and the completion. Max output is 16,000 tokens per request. If you do not set max_tokens, the limit defaults to 2,048 tokens. This capacity is sufficient for most long-form generation tasks.
Cost comparison: OpenRouter vs us
OpenRouter charges per token for each model. Prices vary significantly depending on the provider. Free tiers allow limited usage but do not scale well. Paid tiers require subscriptions or monthly credits. If you exceed your daily limit, you must wait or pay for a higher tier.
Our pricing is straightforward and transparent. We charge $0.15 per 1M input tokens. Output tokens cost $0.50 per 1M tokens. You pay for real token usage. Errors and refusals are free. There is no monthly fee. No subscription is required. Your prepaid credit never expires.
This model is ideal for developers who want predictable costs. You top up your account with crypto. The price per token is fixed. You do not need to worry about model-specific rate changes. Your code keeps running without hitting sudden 429 errors. The prepaid credit system ensures you only pay for what you use.
Model availability: abliterated models
OpenRouter offers a wide selection of models from various providers. Users can choose from Llama, Mistral, and other popular architectures. Some models are modified to be less restrictive. These are often called abliterated models. They remove common refusals while keeping general intelligence.
We focus on one specific uncensored model. The model id is 'uncensored'. It is an open-weight model run on our own servers. It is tuned to answer without content refusals for lawful adult use. It is not GPT, Claude, Gemini, Grok, DeepSeek, Qwen, Llama, or any other vendor's model.
This model supports streaming via SSE. You can use function calling with tools. JSON mode is available with response_format json_object. Parameters like temperature, top_p, stop, seed, presence_penalty, and frequency_penalty are fully supported. This gives you fine-grained control over the generation process.
Rate limits and concurrency
Rate limits determine how many requests you can send in a given time frame. OpenRouter's free tier limits you to 50 requests per day for some models. This is a hard cap that resets daily. If you run out, you must wait.
Our API allows 300 requests per minute. This is a rolling window. It resets continuously. You can send 300 requests in one minute, then wait one minute, and send another 300. This is much more flexible than a daily cap.
Concurrency is limited to 8 requests at the same time per key. This prevents a single client from overwhelming the server. If you need higher concurrency, you can generate more keys. Each account supports one active key. A new key replaces the old one. This design ensures stability for your application.
Pricing tiers and bonuses
We offer a simple prepaid credit system. You top up with crypto only. USDT on TRC20 or USDC on Base are accepted. Any whole amount from $20 to $500 is allowed. There are no monthly fees. No subscription is required. Your credit never expires.
Bonus credit is added to your account. You get +5% bonus from $50. +10% bonus from $100. +15% bonus from $200. This bonus is added to your prepaid balance. It extends the life of your credit. You do not need to pay more to get more value.
New accounts get $0.50 of trial credit. It is valid for 7 days. One per person. Sign up with Google or email and password. The key is shown immediately. No phone number is required. Mistakes like double charges are fixed through the Support page. Credit is not refunded, but it never expires.
SDK compatibility
Our API is fully OpenAI-compatible. You can use the official OpenAI SDKs. Change the base URL to HTTPS://api.openrouterlimits.com/v1. Change the API key to your own key. The rest of your code remains the same.
This compatibility extends to any OpenAI-compatible client. You can use libraries like LangChain, LlamaIndex, or custom HTTP clients. The endpoint is POST /v1/chat/completions. You can also list models with GET /v1/models. No embeddings, no image, audio or video generation. No fine-tuning. Just text in, text out.
Streaming is supported via SSE. Token usage is included in the last chunk. This allows you to track costs in real time. Function calling and JSON mode are also supported. The parameters are identical to the OpenAI API. This makes migration effortless.
Frequently asked questions
How do I integrate with your uncensored API? Install your preferred OpenAI SDK. Set the base_url to HTTPS://api.openrouterlimits.com/v1. Set the API key to your key. Call chat.completions.create with model 'uncensored'. The rest of the parameters are standard. Streaming, JSON mode, and function calling work as expected. No code changes are needed beyond the base URL.
Is the trial credit enough to test the API? Yes, every new account gets $0.50. It is valid for 7 days. You can test streaming, function calling, and JSON mode. The cost is low enough to verify compatibility. If you need more, you can top up with crypto. The trial is one per person.
Do you support abliterated models? We offer one uncensored model. It is tuned for lawful adult use. It does not refuse controversial topics. It is not a specific vendor's model. It is an open-weight model run on our servers. It supports all standard parameters. You can adjust temperature and top_p for better control.
What happens if I exceed my rate limit? You receive a 429 error. The limit is 300 requests per minute. Concurrency is limited to 8 requests. Request bodies are capped at 8 MB. You can wait for the window to reset. Or you can generate a new key. Each account supports one active key. A new key replaces the old one. This allows you to bypass the limit if needed.
