What getHistoricalInflation does on API Ninjas
AI agents call getHistoricalInflation 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 |
|---|---|---|---|
type | string | — | Inflation indicator type. Can be either CPI (Consumer Price Index) or HICP (Harmonized Index of Consumer Prices). If not provided, the CPI will be used by defau |
country | string | Yes | Either the 2-letter country code (ISO-3166-1 alpha-2) or the country name (case-insensitive). |
end_time | integer | — | End time for the data range, specified as a UNIX timestamp in seconds. |
start_time | integer | — | Start time for the data range, specified as a UNIX timestamp in seconds. |
Parameters from the server's own tool schema.
Why getHistoricalInflation is rated Low
Even though getHistoricalInflation 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 getHistoricalInflation 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 getHistoricalInflation, this is the rule to start with:
getHistoricalInflation 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 getHistoricalInflation call is checked against it from then on.
