What is CNY Rate Calculator?
This skill provides a streamlined way to monitor and calculate Chinese Yuan (CNY) exchange rates directly from the Bank of Taiwan. By leveraging Openclaw Skills, developers and business owners can automate the calculation of mid-market rates and apply specific discount tiers based on the Prairie Grasslands formula. It serves as a bridge between financial data sources and communication platforms, ensuring team members have access to the latest cost calculations in real-time.
The tool is designed for high compatibility, supporting a vast array of messaging platforms including Telegram, Discord, Slack, and even enterprise solutions like WhatsApp and Signal through integrated gateways. Its ability to auto-detect system configurations makes it a highly efficient addition to any Openclaw Skills collection.
CNY Rate Calculator Use Cases
- Monitoring live CNY to TWD exchange rates for business procurement.
- Automating price updates in team communication channels like Slack or Discord.
- Calculating tiered discount costs for 10K and 50K thresholds during bulk currency operations.
- Creating a scheduled reporting system for daily exchange rate fluctuations to track market trends.
How CNY Rate Calculator Works
- The skill initiates a request to the Bank of Taiwan's public exchange rate portal to fetch the latest buy and sell prices for CNY.
- It calculates the mid-market price by averaging the buy and sell rates.
- The Prairie Grasslands formula is applied to generate three specific tiers: Base cost (Mid + 0.05), 10K discount (Mid + 0.03), and 50K discount (Mid + 0.015).
- The skill checks for configuration via config.json, environment variables, or existing Openclaw Skills system settings.
- The formatted results are dispatched to the configured communication channel such as a Telegram Bot or a Webhook.
CNY Rate Calculator Setup
Configure your desired channel in config.json or ensure your environment variables (like TELEGRAM_BOT_TOKEN) are set. To use with Openclaw Skills auto-detection, ensure your system configuration is located in the standard ~/.openclaw/ directory.
Run the script using the following command:
python scripts/cny_rate.py
To view the interactive setup guide and see all available channel options, use:

CNY Rate Calculator Data Schema & Taxonomy
The skill organizes its calculation logic and transmission settings as follows:
| Data Point | Description | Calculation Formula |

| 10K Discount | Tier 1 volume discount | Mid + 0.03 |
| 50K Discount | Tier 2 volume discount | Mid + 0.015 |
Configuration is managed via config.json which tracks the channel.type and channel.target metadata to ensure accurate message delivery.
