Quick Start

Get Started Free

Every new account includes 100 million free tokens — no payment details required.

Account Setup

Create an Inception Platform account or sign in directly if you already have one. Each new user is initially assigned 100 million free tokens to help get started with the API.
Go to API Keys and create a new API key. You can start using the API immediately with your free tokens!
When your free tokens are running low, navigate to Billing to add your payment information for continued usage beyond the free tier.

Set your API key

Export your API key as an environment variable in your terminal.

export INCEPTION_API_KEY="your_api_key_here"

set INCEPTION_API_KEY=your_api_key_here

$env:INCEPTION_API_KEY="your_api_key_here"

Install the SDK

pip install inceptionai

npm install inceptionai

Using Third-Party Libraries

Inception API is also fully compatible with popular Python libraries:

import os
import aisuite as ai

client = ai.Client(
    {
        "inception": {"api_key": os.environ["INCEPTION_API_KEY"], "base_url": "https://api.inceptionlabs.ai/v1"},
    }
)

response = client.chat.completions.create(
    model="inception:mercury-2",
    messages=[{"role": "user", "content": "What is a diffusion model?"}],
    max_tokens=8192
)
print(response.choices[0].message.content)

from litellm import completion

# Inception is a native LiteLLM provider; reads INCEPTION_API_KEY from the environment
response = completion(
    model="inception/mercury-2",
    messages=[{"role": "user", "content": "What is a diffusion model?"}],
    max_tokens=8192,
)
print(response.choices[0].message.content)

import os
from langchain_openai import ChatOpenAI
from langchain_core.prompts import ChatPromptTemplate

llm = ChatOpenAI(
    model="mercury-2",
    temperature=0.75,
    api_key=os.environ["INCEPTION_API_KEY"],
    base_url="https://api.inceptionlabs.ai/v1"
)
llm.invoke([("user", "What is a diffusion model?")])

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["INCEPTION_API_KEY"],
    base_url="https://api.inceptionlabs.ai/v1"
)

response = client.chat.completions.create(
    model="mercury-2",
    messages=[{"role": "user", "content": "What is a diffusion model?"}],
    max_tokens=8192
)
print(response.choices[0].message.content)

import { createOpenAICompatible } from '@ai-sdk/openai-compatible';
import { generateText } from 'ai';

const provider = createOpenAICompatible({
  name: 'inception',
  apiKey: process.env.INCEPTION_API_KEY,
  baseURL: 'https://api.inceptionlabs.ai/v1',
});

const { text } = await generateText({
  model: provider('mercury-2'),
  prompt: 'What is a diffusion model?',
});
