What getHolidays does on API Ninjas
AI agents call getHolidays 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 | — | Return only one type of holiday. Not case-sensitive: `PUBLIC_HOLIDAY` and `public_holiday` are equivalent, and `major_holiday` is accepted as an alias of `publi |
year | integer | — | Calendar year between 2005 and 2039 (inclusive). Defaults to the current year. Free plans can omit it or pass the current year; other years are for premium subs |
country | string | Yes | Country as a 2-letter ISO 3166-1 alpha-2 code (preferred, e.g. `US`), a 3-letter alpha-3 code (e.g. `USA`) or an English country name (e.g. `United States`). No |

Why getHolidays is rated Low
Even though getHolidays 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 getHolidays 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 getHolidays, this is the rule to start with:
getHolidays 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 getHolidays call is checked against it from then on.
