What getCurrentMetalsPrice does on API Ninjas
AI agents call getCurrentMetalsPrice 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 |
|---|---|---|---|
unit | string | — | Target weight unit. Defaults to the metal's native unit (troy_ounce for precious metals, lb for copper, metric_ton for aluminum). |
metal | string | — | The metal to return. Defaults to gold. xau, xag, xpt, xpd, and aluminium are also accepted as aliases. |
metals | string | — | Comma-separated list of metals for a batch request. Available to Business, Professional, and Enterprise subscribers, or any annual plan. |
currency | string | — | ISO 4217 currency code to convert prices into (e.g., EUR, GBP, INR). Defaults to USD. |
Parameters from the server's own tool schema.
Why getCurrentMetalsPrice is rated Low
Even though getCurrentMetalsPrice 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 getCurrentMetalsPrice 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 getCurrentMetalsPrice, this is the rule to start with:
getCurrentMetalsPrice 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 getCurrentMetalsPrice call is checked against it from then on.
