Important Guidelines
Cryptos: Use IDs | Stocks: Use Tickers
- Cryptocurrencies: Always use Coin IDs (slugs) instead of ticker symbols (e.g.,
bitcoin,BTC). - Stocks: Always use Ticker Symbols (e.g.,
AAPL,Apple).
Use search_coins.js if you are unsure of the correct ID.
Authentication
Authentication is handled automatically by the internal api_client.js. Here is how it works simply:
- Endpoint:
GET https://api.igent.net/api/token - Mechanism:
- Automatic Retrieval: The first time you use a tool, it asks the server for a temporary session token.
- Local Storage: This token is stored in a hidden
.tokenfile locally so it can be reused for subsequent requests. - Automatic Headers: The client automatically includes this token in every request to prove you are authorized.
- Auto-Refresh: If a token expires, the client automatically fetches a new one without you needing to do anything.
No manual API keys or configuration are required.
Rate Limiting
While the system is robust, please avoid burst requests (more than 30 per minute) to maintain service stability for all users.
Agent Integration
This skill is fully compatible with OpenClaw and other agents using the AgentSkills standard. Execute scripts directly from the scripts/ directory.
