skills/ directory:skills/ folder. No additional configuration is needed beyond setting the API key.Configuration
API Key
The skill requires aZINC_API_KEY environment variable. Set it in your shell before starting your agent:
Get your API key from theZinc dashboard. You’ll need to create an account and deposit funds to place orders.
OpenClaw Configuration File
If you’re using OpenClaw, you can set the API key through the configuration file instead of an environment variable:~/.openclaw/openclaw.json
Verifying the Installation
After installing, start your agent and ask it something like:“List my recent Zinc orders.”If the skill is loaded correctly, the agent will make a
GET /orders request to the Zinc API and return your order history. If you see an authentication error, double-check that your ZINC_API_KEY is set correctly.
