What is Connectors Available?
The connectors-available skill is a powerful diagnostic utility designed for algorithmic traders using Openclaw Skills. It allows users to verify which cryptocurrency exchange connectors are accessible from their current network location, ensuring that API connections are functional before deploying strategies. Beyond connectivity, the skill indexes critical trading rules—such as minimum order sizes, price increments, and supported order types—across all available exchanges.
By centralizing this data, the skill eliminates the need for manual API documentation searches. It provides a streamlined way to discover where specific tokens are traded and what the technical constraints are for each market, making it an essential component for anyone building robust trading automation within the Openclaw Skills ecosystem.
Connectors Available Use Cases
- Verifying geographic accessibility for specific exchange APIs.
- Finding the lowest minimum order size for a specific token across different exchanges.
- Confirming if an exchange supports specific order types like Limit or Market for a pair.
- Building a local database of trading rules to optimize order execution logic.
How Connectors Available Works
- The user requests a connectivity test for all connectors, specific exchanges, or market types (Spot/Perpetual).
- The skill runs a background script to ping the exchanges and fetch the latest trading rules.
- Results are automatically saved to a local JSON file to create a persistent data reference.
- When a user queries a specific token, the skill searches the local database and generates a comprehensive Markdown table showing all available markets and their respective rules.
