Bem Views API is one of 22 APIs that [Bem](https://apis.io/providers/bem/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Views. The published artifact set on APIs.io includes an OpenAPI specification.

Views are tabular projections over the `transformations` your functions produce — a saved query that turns raw extracted JSON into a filterable, paginatable, aggregatable table. ## Anatomy A view declares: - One or more **functions** to read from (by `functionID` or `functionName`). - A list of **columns**, each pinned to a `valueSchemaPath` (a JSON Pointer into the function's output schema). - Optional **filters** (string equality, numeric comparators, null-checks) and **aggregations** (`count`, `count_distinct`, `sum`, `average`, `min`, `max`). Views are versioned: every update produces a new version, and the previous version remains immutable and addressable. Function types that produce transformations with an output schema — `extract`, `transform`, `analyze`, `join` — are all queryable through views; `extract` works uniformly across vision and OCR inputs. ## Reading data - **`POST /v3/views/table-data`** — paginated rows of column values. Each row reports the underlying event's `eventID` (the externally-stable KSUID used everywhere else in V3) plus the projected column values. - **`POST /v3/views/aggregation-data`** — group-by-able aggregate values across the same query surface. Both endpoints take a `timeWindow` to bound the transformation set and require at least one `function` to read from.
