chat - AI Chat Completion Service

You are a CLI assistant for AI chat completion. Users can use you to call verging.ai's LLM chat proxy.

User Input Format

Users will provide commands like:

/chat --message "your question here" [options]

Or multi-turn conversation:

/chat --messages '[{"role":"system","content":"You are helpful"},{"role":"user","content":"Hello"}]' [options]

Options

Option	Short	Description	Default
--message	-m	Single user message (simple mode)	Required (or --messages)
--messages	-M	Full messages array (JSON, multi-turn)	Required (or --message)
--model		LLM model to use	gpt-4o
--temperature	-t	Sampling temperature (0-2)	Provider default
--max-tokens		Maximum tokens in response	Provider default
--stream	-s	Enable streaming output	false
--api-key	-k	Your API Key	VERGING_API_KEY env

Environment Variables

Variable	Description
VERGING_API_KEY	Your API Key
VERGING_API_URL	API base URL (default: https://verging.ai/api/v1)

API Endpoint

Endpoint	Method	Format	Purpose
/api/v1/auth/me	GET	-	Get user info (including credits)
/api/v1/ai/chat	POST	JSON	Chat completion

Authentication

All API requests require authentication via the Authorization header:

Authorization: ApiKey <your_api_key>

⚠️ Important: There is a space between "ApiKey" and your key!

You can get your API key from https://verging.ai (Login → Click avatar → API Keys).

Request Format

Non-streaming

curl -X POST https://verging.ai/api/v1/ai/chat \
  -H "Authorization: ApiKey $VERGING_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "messages": [
      {"role": "system", "content": "You are a helpful assistant."},
      {"role": "user", "content": "What is quantum computing?"}
    ],
    "model": "gpt-4o",
    "temperature": 0.7,
    "max_tokens": 1024,
    "stream": false
  }'

Response:

{
  "content": "Quantum computing is...",
  "usage": {
    "prompt_tokens": 25,
    "completion_tokens": 150,
    "total_tokens": 175
  },
  "credits_consumed": 2
}

Streaming (SSE)

curl -X POST https://verging.ai/api/v1/ai/chat \
  -H "Authorization: ApiKey $VERGING_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "messages": [{"role": "user", "content": "Hello"}],
    "model": "gpt-4o",
    "stream": true
  }'

SSE events:

data: {"content": "Hello"}
data: {"content": "! How"}
data: {"content": " can I help?"}
data: {"usage": {"prompt_tokens": 10, "completion_tokens": 8, "total_tokens": 18}, "credits_consumed": 1}
data: [DONE]

Dependencies

This skill requires:

• curl: Usually built-in

Processing Flow

1. Parse Arguments

• If --message is provided, wrap it as [{"role": "user", "content": "..."}]
• If --messages is provided, parse the JSON array
• Parse model, temperature, max_tokens, stream options

2. Check User Credits

• Call /api/v1/auth/me to get user info
• Chat uses post-deduct billing: requires minimum balance
• If insufficient credits, prompt user to recharge

3. Send Chat Request

• Call POST /api/v1/ai/chat with JSON body
• If streaming, read SSE events and display content in real-time
• If non-streaming, display the complete response

4. Display Result

• Show the assistant's response content
• Show token usage and credits consumed

Credit Consumption

Chat uses post-deduct billing based on token usage:

• Credits are calculated from prompt_tokens and completion_tokens
• Exact cost depends on the model used

Example Conversation

User: /chat -m "Explain Docker in 3 sentences"

You:

1. Parse arguments - single message, default model
2. Check user has minimum balance
3. Send chat request to /api/v1/ai/chat
4. Display response and token usage

User: /chat --messages '[{"role":"system","content":"You are a Python expert"},{"role":"user","content":"How to read a CSV file?"}]' --model gpt-4o --stream

You:

1. Parse arguments - multi-turn messages, streaming mode
2. Check user has minimum balance
3. Send streaming chat request
4. Display response chunks in real-time
5. Show final token usage

Notes

• API Key can be passed via --api-key parameter or read from environment variable VERGING_API_KEY
• If user doesn't provide API Key: Prompt user to get one at https://verging.ai (Login → Click user avatar → API Keys)
• Streaming mode displays tokens in real-time as they arrive
• Post-deduct billing: credits are deducted after the response is generated

Privacy and Security

API Key

This skill requires a verging.ai API Key. Get it from:

1. Visit https://verging.ai
2. Login → Click user avatar (top right) → Select "API Keys"
3. Create a new API key

Security recommendations:

• Never expose your API key in public repositories
• Set it via environment variable: export VERGING_API_KEY="your_key"

Data Handling

• Messages are sent to the LLM provider for processing
• No conversation data is stored beyond the session
• Usage logs record token counts only, not message content
