What getShortInterest does on API Ninjas
AI agents call getShortInterest 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 |
|---|---|---|---|
limit | integer | — | Number of historical settlement dates to return, 1 to 200. Defaults to 12. The free tier is limited to the latest date. |
ticker | string | Yes | The stock or ETF ticker symbol (e.g., GME). |
settlement_date | string | — | Return a specific settlement date in YYYY-MM-DD format. Short interest settles on the 15th and the last business day of each month. |
Parameters from the server's own tool schema.
Why getShortInterest is rated Low
Even though getShortInterest 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 getShortInterest 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 getShortInterest, this is the rule to start with:
getShortInterest 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 getShortInterest call is checked against it from then on.
