Quickstart for Claude users

Authentication & Base URL

Our API follows the OpenAI compatibility standard, meaning you likely already have the client libraries needed to connect. All requests require a valid API key passed in the Authorization header. The base URL for all endpoints is https://api.claudeapicost.com/v1. You can generate your key on the "Get API key" page using just an email and password. No credit card is required to start, and you receive $0.50 in trial credit valid for 7 days. Keep your key secure, as it can be regenerated at any time to revoke access.

First Request

Send a standard chat completion request to start generating text. The model ID is always uncensored. This endpoint supports both streaming and non-streaming responses. Below is a basic example using cURL to send a simple prompt and receive a text response.

Use this structure to verify connectivity before integrating into your application. The response includes the generated text in the choices array.

• Endpoint: POST /v1/chat/completions
• Model: uncensored
• Response: JSON object with text content

Copycurl https://api.claudeapicost.com/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."}]
  }'

Python SDK Integration

For Python developers, the official openai package works directly with our service by overriding the base URL. This approach lets you use familiar SDK methods like client.chat.completions.create(). Ensure you set the base_url parameter to our endpoint and provide your API key. This method is ideal for backend services or scripts where you need structured text output without managing raw HTTP requests.

Copyfrom openai import OpenAI

client = OpenAI(base_url="https://api.claudeapicost.com/v1", api_key="YOUR_KEY")

resp = client.chat.completions.create(
    model="uncensored",
    messages=[{"role": "user", "content": "Summarise this thread without softening it."}],
)
print(resp.choices[0].message.content)

Node.js SDK Integration

Node.js developers can achieve the same compatibility by adjusting the baseUrl in the OpenAI SDK configuration. This allows you to integrate our uncensored model into existing Node applications with minimal code changes. The SDK handles tokenization and request formatting, so you can focus on prompt engineering. Remember to pass the model ID uncensored in your completion requests.

Copyimport OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://api.claudeapicost.com/v1", apiKey: process.env.API_KEY });

const resp = await client.chat.completions.create({
  model: "uncensored",
  messages: [{ role: "user", content: "Draft a villain monologue for my game." }],
});
console.log(resp.choices[0].message.content);

Streaming Responses via SSE

For applications requiring real-time text generation, we support Server-Sent Events (SSE). Streaming reduces perceived latency by delivering tokens as they are generated. Set the stream parameter to true in your request. The client will receive a series of data events containing partial content. This is particularly useful for chat interfaces or live data feeds where immediate feedback is critical to user experience.

Copystream = client.chat.completions.create(
    model="uncensored",
    messages=[{"role": "user", "content": "Tell the story in second person."}],
    stream=True,
)
for chunk in stream:
    if chunk.choices and chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)

Rate Limits & Constraints

Our service enforces strict limits to ensure stability. You are allowed 300 requests per minute per API key. The maximum request body size is 8 MB. If your key is invalid or expired, you will receive a 401 error. If your prepaid credit is exhausted, you will see a 402 error requiring a top-up. A 429 status indicates you have exceeded the rate limit. The context window supports 100,000 tokens for both prompt and completion combined. Credits are prepaid and never expire, with bonuses available for larger top-ups.
