Opal Assets API

## Assets Overview Assets represent images, videos, PDFs, and any other file uploads. Any upload to the Opal platform must start with an `asset`. Some resources like `boards` can be directly related to an `asset` while other resources like `moments` require that you also create an `asset_reference` that further describes your `asset`. Assets can either be created by uploading data directly or by creating a Url Upload that requests an asset from some other publicly available web address and streams it to Opal. The former endpoint is described immediately below and the latter option can be found under the [Url Uploads](#tag/Url-Uploads) tag. Once you've created an Asset and you have its `id`, you'll likely want to create an [Asset Reference](#tag/Asset-References) as well, unless you don't want your asset exposed in the Asset Library or used with other resources you'll find to have asset reference relationships.

Operations 3

POST /assets/v2 Upload an asset available to the authenticated user #
GET /assets/v2 [UNSTABLE] Get a collection of assets available to the authenticated user #

                Supports the comparison operators: `eq` (equal to), `gt` (greater than),

                `gteq` (greater than or equal to), `lt` (less than), and `lteq` (less than or

                equal to).


                Filters are formatted as `filter[created_at][gt]=2025-01-01T12:01:00Z` where

                `created_at` is the field you want to filter on, `gt` is the operator, and

                `2025-01-01T12:01:00Z` can be either a date or date-time value.


                If no operator is specified, `eq` is assumed but date values without time

                components will have the semantics of matching all records "on the same day"

                as the given date. For example, `filter[created_at]=2025-01-01T12:01:00Z` is

                equivalent to `filter[created_at][eq]=2025-01-01T12:01:00Z` which will only

                match that exact date and time. Alternatively,

                `filter[created_at]=2025-01-01` has the semantics "greater than midnight on

                2025-01-01 and less than midnight on 2025-01-02."

              description: 'Filter for exact dates or for dates greater than or less than a given date.


                Supports the comparison operators: `eq` (equal to), `gt` (greater than),

                `gteq` (greater than or equal to), `lt` (less than), and `lteq` (less than or

                equal to).


                Filters are formatted as `filter[created_at][gt]=2025-01-01T12:01:00Z` where

                `created_at` is the field you want to filter on, `gt` is the operator, and

                `2025-01-01T12:01:00Z` can be either a date or date-time value.


                If no operator is specified, `eq` is assumed but date values without time

                components will have the semantics of matching all records "on the same day"

                as the given date. For example, `filter[created_at]=2025-01-01T12:01:00Z` is

                equivalent to `filter[created_at][eq]=2025-01-01T12:01:00Z` which will only

                match that exact date and time. Alternatively,

                `filter[created_at]=2025-01-01` has the semantics "greater than midnight on

                2025-01-01 and less than midnight on 2025-01-02."
