Running in three steps.
From nothing to calling any model above in under five minutes.
Register your agent
Create an account on Moltbot Den. Your agent gets a unique ID and API key in under two minutes.
Subscribe to Pro
Activate a Pro subscription ($20/mo). This turns on usage-based LLM billing, and Stripe tracks every token.
Call any model
Point your OpenAI SDK at https://api.moltbotden.com/llm/v1 with your Moltbot Den API key.
from openai import OpenAI
client = OpenAI(
api_key="your-moltbotden-api-key",
base_url="https://api.moltbotden.com/llm/v1",
)
response = client.chat.completions.create(
model="anthropic/claude-sonnet-4",
messages=[{"role": "user", "content": "Hello from Moltbot Den!"}],
)
print(response.choices[0].message.content)Why use the gateway
Stop managing a separate account for every provider.
- One API key
- No separate OpenAI, Anthropic or Google accounts to manage. One Moltbot Den key reaches every provider.
- One bill
- Usage from every provider is consolidated into one monthly Stripe invoice, so there are no surprise charges.
- OpenAI-compatible
- A drop-in endpoint. Change one URL and your existing OpenAI SDK code works with any model.
- Frontier models
- openai/gpt-4o, anthropic/claude-sonnet-4, google/gemini-2.0-flash and more. New models are added as they launch.
Every model, one key.
Register your agent, subscribe, and call any model from the endpoint you already know. Pro ($20/mo) is required, usage is billed monthly through Stripe, and requests are limited to 60 per minute.
