What getCommodityContract does on API Ninjas
AI agents call getCommodityContract to retrieve information from API Ninjas without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
symbol | string | — | Specific contract symbol to look up (e.g., GCK26). |
symbol_root | string | — | Commodity root to filter contracts (e.g., GC returns all contracts starting with GC like GCK26, GCM26, etc.). |
Parameters from the server's own tool schema.
Why getCommodityContract is rated Low
Even though getCommodityContract only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

The rule that runs getCommodityContract safely
PolicyLayer is an MCP gateway: it sits between your AI agents and API Ninjas, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For getCommodityContract, this is the rule to start with:
getCommodityContract is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect API Ninjas, apply this rule, and every getCommodityContract call is checked against it from then on.
