GPT, Claude and more — billed per token

Use the best models with no provider sign-up. Pay only for the tokens you actually consume, straight from your balance. Every model is available through a single endpoint.

BYOK — your own key

OpenAI, Anthropic, DeepSeek — your choice

Connect your own API key from any provider. Pay the provider directly, free through the platform. Your keys — your models — your limits.

One request — any model

curl /v1/ai/chat/completions
curl -X POST /v1/ai/chat/completions \
  -H "X-Api-Key: vibe_app_xxx..." \
  -d '{
    "model": "auto",
    "messages": [
      { "role": "user", "content": "Hello!" }
    ],
    "stream": true
  }'

Standard OpenAI-compatible format. Copy and paste — it works out of the box.

  • Automatic model selection — set "auto" and forget about it
  • SSE streaming — instant, real-time responses
  • Key cascade — user, portal, platform
  • OpenAI-compatible — works with any SDK

Prompts for building bots

Don't write code by hand. Copy a prompt, paste it into Claude, Cursor or ChatGPT — the AI assistant builds a working bot for you.

CRM bot for lead classification

Build a bot for Bitrix24 that automatically classifies incoming leads with AI.

Task:
- The bot receives a new lead via a Bitrix24 webhook
- It sends the lead description to an AI model through the VibeCode API
- The AI analyzes the text and assigns a category: hot, warm, cold
- The bot updates the lead field in the CRM with the classification result

Stack:
- VibeCode API to access Bitrix24 and the AI models
- AI endpoint: POST /v1/ai/chat/completions with model: "auto"
- CRM endpoint: GET/POST /v1/leads to work with leads
- API key: vibe_app_xxx (replace with your own)

Connecting your own key (BYOK)

Three steps and your models run through VibeCode. Free, no commission.

1

Get a key from a provider

OpenAI, Anthropic, Google AI, DeepSeek, OpenRouter — sign up and create an API key.

2

Add the key to VibeCode

Through the interface or the API — specify the provider and your key. Data is encrypted with AES-256-GCM.

3

Start sending requests

Your key is picked up automatically. Priority cascade: your key → portal → platform.

BYOK = free through the platform. When you use your own key, VibeCode takes no commission. You pay only the provider, directly.

Frequently asked questions about AI models

How the AI Model Router works

Which models are free?

Six free models: BitrixGPT 5.5 (with image support), BitrixGPT 5.5 Thinking (with reasoning), GPT-OSS 120B, BitrixGPT 5.5 Agent, Gemma 4 26B and Gemma 4 26B Thinking. Plus Whisper for speech recognition. All available through a single endpoint /v1/ai/chat/completions.

What is BYOK (Bring Your Own Key)?

BYOK lets you connect your own API keys from OpenAI, Anthropic, DeepSeek or any OpenAI-compatible provider. Your requests go through the VibeCode proxy with a unified format and logging.

Is streaming supported?

Yes. Full support for Server-Sent Events (SSE) for streaming responses. Set stream: true in the request — and the model returns tokens as they are generated.

Is there function calling?

Yes. The AI API supports tools/function calling in the OpenAI format. The model can call functions, receive results and continue generation — ideal for AI agents and automation.
