When you use the\nAPI, you get a list of the entities that were recognized: people, things,\nplaces, activities, and so on. Each label found comes with a score that\nindicates the confidence the ML model has in its relevance. With this\ninformation, you can perform tasks such as automatic metadata generation\nand content moderation.\n\n\u003cbr /\u003e\n\nReady to get started?

(See below.) Try it yourself with the [Cloud Vision API demo](https://cloud.google.com/vision/docs/drag-and-drop). |\n| Knowledge Graph entity support | In addition the text description of each label that Firebase ML returns, it also returns the label's Google Knowledge Graph entity ID. This ID is a string that uniquely identifies the entity represented by the label, and is the same ID used by the [Knowledge Graph Search API](https://developers.google.com/knowledge-graph/). You can use this string to identify an entity across languages, and independently of the formatting of the text description. |\n| Limited no-cost use | No-cost for first 1000 uses of this feature per month: see [Pricing](/pricing) |\n\nExample labels\n\nThe image labeling API supports 10,000+ labels, including the following examples\nand many more:\n\n| Category | Example labels | Category | Example labels |\n|------------------------|------------------------------------------|----------------------|-----------------------------------------------|\n| Arts \\& entertainment | `Sculpture` `Musical Instrument` `Dance` | Astronomical objects | `Comet` `Galaxy` `Star` |\n| Business \\& industrial | `Restaurant` `Factory` `Airline` | Colors | `Red` `Green` `Blue` |\n| Design | `Floral` `Pattern` `Wood Stain` | Drink | `Coffee` `Tea` `Milk` |\n| Events | `Meeting` `Picnic` `Vacation` | Fictional characters | `Santa Claus` `Superhero` `Mythical creature` |\n| Food | `Casserole` `Fruit` `Potato chip` | Home \\& garden | `Laundry basket` `Dishwasher` `Fountain` |\n| Activities | `Wedding` `Dancing` `Motorsport` | Materials | `Ceramic` `Textile` `Fiber` |\n| Media | `Newsprint` `Document` `Sign` | Modes of transport | `Aircraft` `Motorcycle` `Subway` |\n| Occupations | `Actor` `Florist` `Police` | Organisms | `Plant` `Animal` `Fungus` |\n| Organizations | `Government` `Club` `College` | Places | `Airport` `Mountain` `Tent` |\n| Technology | `Robot` `Computer` `Solar panel` | Things | `Bicycle` `Pipe` `Doll` |\n\nExample results Photo: Clément Bucco-Lechat / Wikimedia Commons / CC BY-SA 3.0\n\n| Label | Knowledge Graph entity ID | Confidence |\n|-------------------------|---------------------------|------------|\n| sport venue | /m/0bmgjqz | 0.9860726 |\n| player | /m/02vzx9 | 0.9797604 |\n| stadium | /m/019cfy | 0.9635762 |\n| soccer specific stadium | /m/0404y4 | 0.95806926 |\n| football player | /m/0gl2ny2 | 0.9510419 |\n| sports | /m/06ntj | 0.9253524 |\n| soccer player | /m/0pcq81q | 0.9033665 |\n| arena | /m/018lrm | 0.8897188 |"]]
