What getHistoricalOilPrice does on API Ninjas
AI agents call getHistoricalOilPrice 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 |
|---|---|---|---|
end | integer | — | End timestamp in Unix format. |
type | string | — | The oil/energy benchmark. Defaults to wti. crude_oil, brent_crude_oil, gasoline_rbob, and heating_oil are also accepted as aliases. |
start | integer | — | Start timestamp in Unix format. |
period | string | — | Time interval between data points. |
Parameters from the server's own tool schema.
Why getHistoricalOilPrice is rated Low
Even though getHistoricalOilPrice 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.
Attacks that exploit this kind of access
The rule that runs getHistoricalOilPrice 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 getHistoricalOilPrice, this is the rule to start with:
getHistoricalOilPrice 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 getHistoricalOilPrice call is checked against it from then on.
