DarkGPT API: An OpenAI-Compatible AI API, Pay Per Token

Why use the DarkGPT API?

• Standard format: the /v1/chat/completions endpoint follows the most widely used format, compatible with most existing libraries.
• Many providers, one bill: Claude, Gemini, Grok, DeepSeek, Mistral, GLM… without opening an account with each one.
• Pay as you go: billed per 1,000 tokens, from your API & IDE credit, which you can top up from €10.
• Revoke your key at any time from your “API Keys” page.

Get started in 3 steps

1. Create your keyOn your “API Keys” page on darkgpt.chat. It always starts with dgpt_live_.
2. Pick your modelEach key is tied to the model you select in your dashboard (for example claude-4.6-sonnet, gemini-3.5, grok-4.2, deepseek-v4-pro, ministral-14b).
3. Send your requestA simple POST with your messages, and the response comes back as JSON.

You’ll need credit: buy API & IDE Credit on the shop (from €10), then send your order number and your account email to support so it gets added.

Authentication

The API uses Bearer keys. The base URL is https://darkgpt.chat/v1 and every request carries this header:

Authorization: Bearer dgpt_live_xxxxxxxxxxxxxxxxxxxx

Send a message: /v1/chat/completions

JavaScript

const response = await fetch("https://darkgpt.chat/v1/chat/completions", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "Authorization": "Bearer dgpt_live_YOUR_API_KEY"
  },
  body: JSON.stringify({
    model: "claude-4.6-sonnet",
    messages: [
      { role: "system", content: "You are a direct, concise assistant." },
      { role: "user", content: "Explain reverse engineering to me." }
    ],
    temperature: 0.7
  })
});
const data = await response.json();
console.log(data.choices[0].message.content);

Python

import requests

res = requests.post(
    "https://darkgpt.chat/v1/chat/completions",
    headers={"Authorization": "Bearer dgpt_live_YOUR_API_KEY"},
    json={
        "model": "claude-4.6-sonnet",
        "messages": [{"role": "user", "content": "Summarize this text in 3 bullet points."}],

curl -X POST https://darkgpt.chat/v1/chat/completions \
  -H "Authorization: Bearer dgpt_live_YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"claude-4.6-sonnet","messages":[{"role":"user","content":"Hello"}]}'

Parameters

The response holds the text in choices[0].message.content and a usage block with the token count and the request cost in euros (cost_eur). To list the available models: GET /v1/models.

API pricing

Billing is per 1,000 tokens, with one price for the tokens you send (input) and one for the tokens generated (output). Reminder: 1,000 tokens ≈ 750 words.

Example: with Claude 4.6 Sonnet, a request with 400 input tokens and 600 output tokens costs about €0.0383. The simulator at darkgpt.chat/api works out your daily and monthly budget.

An API that doesn’t break your bot with refusals

The worst thing for a bot or an app is a refusal in the middle of a normal conversation: the user asks an adult question and the API returns a generic apology. Your product looks crippled, and it isn’t even your fault.

With the DarkGPT API, you pick an Unfiltered mode model (Grok, DeepSeek, Qwen, Mistral, Kimi…) and set the tone in your system message: frank, funny, blunt, no disclaimers. Your bot answers the way you decided.

Good habit: a small model for volume (Mistral 14B, Qwen 3 235B), a bigger one for the answers that matter. Adults 18+ only, and illegal use remains banned.

Rate limits

Limits apply per key. The X-RateLimit-Remaining and X-RateLimit-Reset headers let you track your usage in real time.

Error codes

What you can build

• A Discord bot: one !ask command and your server has its own assistant, running the model of your choice.
• An assistant on your website: customer support, a smart FAQ or a built-in chat, called from your backend.
• Your automations: summaries, translations, email sorting or content generation in your scripts, n8n or your own tools.
