Bem Functions 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 Functions. The published artifact set on APIs.io includes an OpenAPI specification.

Functions are the core building blocks of data transformation in Bem. Each function type serves a specific purpose: - **Extract**: Extract structured JSON data from unstructured documents (PDFs, emails, images, spreadsheets), with optional layout-aware bounding-box extraction - **Route**: Direct data to different processing paths based on conditions - **Split**: Break multi-page documents into individual pages for parallel processing - **Join**: Combine outputs from multiple function calls into a single result - **Parse**: Render documents into a navigable structure of page-aware sections, named entities, and relationships — designed to be walked by an LLM agent via the [File System API](/api/v3/file-system) (`POST /v3/fs`). Two toggles, both `true` by default: `extractEntities` controls per-document entity and relationship extraction; `linkAcrossDocuments` merges entities into one canonical record per real-world thing across the environment, populating cross-document memory. - **Payload Shaping**: Transform and restructure data using JMESPath expressions - **Enrich**: Enhance data with semantic search against collections - **Send**: Deliver workflow outputs to downstream destinations Use these endpoints to create, update, list, and manage your functions.
