# What is a Collection Collections are the outputs - reports, visualizations, APIs - built to embed and share with your end-users. Each collection is built using a model in Verb. ### The 3 Collection Types #### Dashboard Collection The dashboard collection allows for a series of tiles/charts and filters to be added and designed. When embedding a dashboard collection the dashboard can be embedded with or separate from the filters. #### Contextual Tile Collection A contextual tile collection contains a single tile/chart that is embedded individually and can accept filter criteria contextually. For example, embedding a sparkline chart in a table. #### [API Collection](/collections/api-collections.md) An API collection defines data, aggregations and filters that are made available as a REST API with auto-generated documentation. API collection can be used to create custom visualizations or to provision key-based access to external users. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
