\

A specification of interactions available for building software to access an application or service.\

\
)* request counts and indicators of attack (IoA) for the specified period. To view the **Top APIs** chart details and drill-down information, click **Dashboard → Top APIs**. ![Screen capture of the top APIs.](_images/ckz1639477873457.png) ## Graph filters The **Trained** graph filters are available. Select or clear the check boxes to include or exclude **Trained** or **Not Trained** APIs, for the specified selection. ## Top APIs table The filtered graph results are displayed in a table below the graph, for further drill-down, inspection and analysis. | Column | Description | | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | API Name | The name of the API. | | Date Added | The date monitoring began on the API. | | Trained | Indicates whether the AI engine is trained (Yes) or not trained (No) on the API. An API must be trained before it can detect IoAs. | | Hostname | The server hosting the API. | | API Base Path | The Uniform Resource Identifier (URI) *(tooltip: \
\

Identifies a web resource with a string of characters conforming to a specified format.\

\
)* prefix for the API path, relative to the host root. | | Requests | Accumulated count of requests to the API for the reported period. | | IoA count | Accumulated count of IoAs on the API for the reported period. | ## Sorting and filtering Click on a table column heading to sort the table according to that column. Click on the column heading again to display a reverse sort according to that column. Click **Filters ^** to select filtering based on search strings or partial strings of the **API Name** or **API Base Path**. Enter the search string in the **Search from table** field. The search displays the matching rows in the table. | | | | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | * The search is case-insensitive. * Wildcard searches, for example using an asterisk (`\*`), are not supported. * Use of quotation marks is not supported. * Be aware of the use of spaces in a search string. A leading or trailing space can filter out results. A single space is not regarded as multiple consecutive spaces. * The graph filters are applied before the table filter. Use of the table filter produces a subset of the graph filter. For example, in the graph filter select **Not Trained**. The graph and the table show not trained data only. The table's **Trained** column only has rows with the value `No`. | Select **API Base Path**in the table filter, and enter `/acc`. The table is reduced further, displaying only the rows where the **API Base Path** column contains the string `/acc`. ## API drill-down In the Top APIs table, click on an API in the **API Name** column, to display the [API activity](pingintelligence_dashboard_api_activity.html) dashboard with further details about that API's activity in the reported period.
