# getFeature {% hint style="warning" %} ### API test authentication The Open API block allows you to test OS APIs directly from the page with example data and parameters. To use this feature, you will need to add your API Key or OAuth2 token to the authentication field. For help generating an API Key or OAuth2 token, please see the [Getting started with an API project](https://docs.os.uk/os-apis/core-concepts/getting-started-with-an-api-project) or [OAuth2 documentation](https://docs.os.uk/os-apis/accessing-os-apis/oauth-2-api). {% endhint %} ## GET /wfs > Access to features matching a given query ```json {"openapi":"3.0.1","info":{"title":"OS Features API","version":"v1.0"},"tags":[{"name":"GetCapabilities","description":"Returns a metadata document describing the WFS service provided by the server as well as valid WFS operations and parameters."},{"name":"DescribeFeatureType","description":"Returns a description of the attributes for each feature type supported by the WFS service."},{"name":"GetFeature","description":"Access to features matching a given query"}],"servers":[{"url":"https://api.os.uk/features/v1"}],"security":[{"api-key":[],"api-key-header":[],"oauth2":[]}],"components":{"securitySchemes":{"api-key":{"type":"apiKey","name":"key","in":"query"}},"schemas":{"FeatureCollection":{"type":"object","properties":{"type":{"type":"string"},"features":{"type":"array","items":{"$ref":"#/components/schemas/Feature"}}}},"Feature":{"type":"object","properties":{"type":{"type":"string"},"geometry":{"$ref":"#/components/schemas/Geometry"},"properties":{"type":"object","additionalProperties":{"type":"object"}}}},"Geometry":{"type":"object","properties":{"type":{"type":"string"},"coordinates":{"type":"array","items":{"$ref":"#/components/schemas/Coordinate"}}}},"Coordinate":{"type":"object","properties":{"x":{"type":"number","format":"double"},"y":{"type":"number","format":"double"}}}}},"paths":{"/wfs":{"get":{"tags":["GetCapabilities","DescribeFeatureType","GetFeature"],"summary":"Access to features matching a given query","operationId":"GetFeature","parameters":[{"name":"request","in":"query","description":"The type of request being made.","required":true,"schema":{"type":"string","default":"GetFeature","enum":["GetCapabilities","DescribeFeatureType","GetFeature"]}},{"name":"service","in":"query","description":"The type of service being requested.","required":true,"schema":{"type":"string","enum":["WFS"]}},{"name":"version","in":"query","description":"The type of service being requested.","required":true,"schema":{"type":"string","default":"2.0.0","enum":["1.0.0","1.1.0","2.0.0"]}},{"name":"typeNames","in":"query","description":"The Feature Type being requested.","required":true,"schema":{"type":"string","enum":["DetailedPathNetwork_RouteLink","DetailedPathNetwork_RouteNode","Highways_RoadLink","Highways_RoadNode","Highways_FerryLink","Highways_FerryNode","Highways_Street","Highways_ConnectingLink","Highways_ConnectingNode","Highways_PathLink","Highways_PathNode","Greenspace_GreenspaceArea","Sites_AccessPoint","Sites_RoutingPoint","Sites_FunctionalSite","Topography_CartographicText","Topography_CartographicSymbol","Topography_TopographicPoint","Topography_TopographicLine","Topography_TopographicArea","Topography_BoundaryLine","WaterNetwork_HydroNode","WaterNetwork_WatercourseLink","Zoomstack_Airports","Zoomstack_Boundaries","Zoomstack_Contours","Zoomstack_DistrictBuildings","Zoomstack_ETL","Zoomstack_Foreshore","Zoomstack_Greenspace","Zoomstack_LocalBuildings","Zoomstack_Names","Zoomstack_NationalParks","Zoomstack_RailwayStations","Zoomstack_Rail","Zoomstack_RoadsLocal","Zoomstack_RoadsNational","Zoomstack_RoadsRegional","Zoomstack_Sites","Zoomstack_Surfacewater","Zoomstack_UrbanAreas","Zoomstack_Waterlines","Zoomstack_Woodland","OpenUPRN_Address","OpenUSRN_USRN","OpenTOID_TopographyLayer","OpenTOID_HighwaysNetwork","OpenTOID_SitesLayer"]}},{"name":"bbox","in":"query","description":"A set of valid WFS BBOX coordinates, in the order (Dependent on CRS)","required":false,"schema":{"type":"string"}},{"name":"filter","in":"query","description":"A valid OGC XML filter object","required":false,"schema":{"type":"string"}},{"name":"count","in":"query","description":"An integer stating the maximum number of features to be returned in a single response.

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.os.uk/os-apis/accessing-os-apis/os-features-api/technical-specification/getfeature.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
