# TrakToken Query Skill

## Instructions

When the user asks about LLM API prices, token costs, or wants to compare local deployment vs API costs, follow these steps:

1. **Fetch Latest Pricing Data**:
   Use the `WebFetch` tool or `Shell` tool (with `curl`) to fetch the latest pricing data from TrakToken's API endpoint:
   ```bash
   curl -s https://token.kuhung.me/api/prices
   ```
   *(Note: If working in a local development environment, use `http://localhost:3000/api/prices` instead)*

2. **Analyze the Data**:
   - Find the requested models in the JSON response (`data` array).
   - Extract `input_price` (per 1M tokens) and `output_price` (per 1M tokens).
   - Note the `context_window` and any special features.

3. **Calculate Costs Based on Scenario**:
   If the user provides a scenario (e.g., "100k messages/day, 500 input tokens, 200 output tokens"):
   - Calculate daily input tokens: `messages * input_tokens`
   - Calculate daily output tokens: `messages * output_tokens`
   - Calculate monthly cost: `(daily_input / 1M * input_price + daily_output / 1M * output_price) * 30`

4. **Compare API vs Local Deployment (If requested)**:
   - Estimate the hardware cost for local deployment (e.g., 1x A100 80G is ~$1500/month on cloud, or ~$15,000 to buy).
   - Compare the monthly API cost with the monthly hardware cost.
   - Calculate the ROI/Breakeven point: `Hardware Cost / Monthly API Cost`.

## Example Usage

**User**: "Compare the cost of using DeepSeek-V3 API vs GPT-4o for a customer service bot doing 10,000 messages a day (avg 1000 input, 500 output tokens)."

**Agent Action**:
1. Fetch pricing for DeepSeek-V3 and GPT-4o.
2. Calculate Monthly Tokens:
   - Input: 10,000 * 1000 * 30 = 300M tokens/month
   - Output: 10,000 * 500 * 30 = 150M tokens/month
3. Calculate Cost:
   - DeepSeek-V3: (300 * $0.14) + (150 * $0.28) = $42 + $42 = $84/month
   - GPT-4o: (300 * $2.50) + (150 * $10.00) = $750 + $1500 = $2250/month
4. Present the comparison clearly to the user.
