Get an unlimited Tavily API Key from Lucifer Tech for a fixed price of 200.000đ per month. You'll receive a pre-made account with an activated Unlimited plan, completely removing the 1,000-credit free tier limit. The key is fully compatible with LangChain, CrewAI, and the Vercel AI SDK, making it ideal for RAG and AI Agent applications that require real-time web data.
When developing AI Agent applications or RAG (Retrieval-Augmented Generation) systems, accessing the latest web data is critical. However, Tavily's free tier of 1,000 credits is often depleted too quickly, interrupting your workflow and stifling creativity. Official paid plans can be expensive and unpredictable, especially for projects in the experimental phase.
Don't let credit limits stop you from building groundbreaking AI applications. With the Tavily API Key Unlimited Plan from Lucifer Tech, you can completely forget about cost and usage caps. For a single fixed monthly fee, you get unlimited search power, allowing you to focus 100% on developing your product.
This solution is specifically designed for AI developers, tackling the three biggest challenges of using Tavily:
To offer the best possible price, we use a "Pre-made account" model. This means:
We are transparent about this model so you understand exactly what you're getting. The advantage is an extremely low and convenient cost. The only thing to note is that you will need to renew and receive a new key each month, but this process is very fast.
For just 200.000đ per month, you can make millions of API calls without worrying about extra costs or interruptions from 'Quota Exceeded' errors.
The API is designed to automatically remove ads and redundant HTML, returning clean text snippets that help minimize hallucinations for AI models like GPT-4.1.
After completing your payment, you will receive your API Key. Here’s how to quickly integrate it into your project.
The best practice is to save your API Key as an environment variable rather than hardcoding it. Create a .env file in your project's root directory and add the following line:
TAVILY_API_KEY="tvly-your-api-key-here"
For Python:
pip install tavily-python

Python example (standalone or with LangChain):
import os
from tavily import TavilyClient
# Get key from environment variable
tavily_api_key = os.getenv("TAVILY_API_KEY")
client = TavilyClient(api_key=tavily_api_key)
# Perform a search
response = client.search(query="What are the latest features of Vercel AI SDK in 2026?")
# Print results
for result in response['results']:
print(f"- {result['title']}: {result['url']}")
JavaScript/TypeScript example:
import { TavilyClient } from "tavily";
const client = new TavilyClient({
apiKey: process.env.TAVILY_API_KEY,
});
const main = async () => {
const response = await client.search("latest AI news 2026");
console.log(response.results);
};
main();
Using with cURL (no SDK needed):
You can also call the API directly:
curl -X POST \
-H "Content-Type: application/json" \
-d '{
"api_key": "tvly-your-api-key-here",
"query": "What is agentic search?",
"search_depth": "advanced",
"max_results": 5
}' \

With just a few simple steps, you can integrate the search power of Tavily into your AI application.
A Pre-made account is an account created and provided to you by Lucifer Tech. We have already activated the Unlimited plan on this account. You simply receive the API Key and start using it. This model allows us to offer the service at a much lower price than if you purchased it yourself, but it means you won't be using your personal email.
We purchase Enterprise plans in bulk and share the resources as individual API keys, thereby optimizing costs. The 'Pre-made account' model allows us to pass these significant cost savings directly to you, individual developers, and small projects.
Yes, for the vast majority of development and normal usage purposes. There is a very high 'fair-use' policy in place to prevent abuse (e.g., running DDoS attacks). For 99.9% of AI Agent and RAG projects, you will never come close to hitting this limit.
Absolutely. The API Key is fully compatible and ready for immediate integration with the most popular AI frameworks today, including LangChain, LlamaIndex, CrewAI, and the Vercel AI SDK (2026 version).
If your API key experiences any issues not caused by you (e.g., it's revoked or expires early) during your 1-month subscription, we will immediately issue a new replacement key to ensure your project is not interrupted. This is our full-period warranty.
Yes. The Tavily API is designed to act as a web-access 'brain' for any LLM. It provides clean and accurate web data to models like GPT-4.1, Claude Sonnet 4.6, and others so they can provide answers based on the latest information, minimizing fabricated content.
The renewal process is simple. Just purchase a new plan on our website. A new API Key will be delivered to you instantly. You just need to update this new key in your project's configuration file (e.g., .env) to continue.
Lucifer Tech accepts two payment methods: (1) Bank transfer via MB Bank (auto-confirmed) and (2) USDT crypto on BSC (BEP20) or TRX (TRC20) networks. After payment, your account is delivered automatically within 5–30 minutes.
