Superlinked Query API

openapi: 3.0.1

  title: Superlinked Server API
  description: >-
    REST API auto-generated by the Superlinked Server from a Superlinked app's
    schema, index, and query definitions. The Superlinked open-source Python
    framework (Apache-2.0) lets you declare Schema, Space, Index, Query, Source,
    and Executor objects; when run with a RestExecutor / RestApp the server
    exposes ingestion and query endpoints whose exact paths and request bodies
    are derived from those definitions. This document models the generated
    pattern using representative, templated path and body names ({schema},
    {query_name}); the concrete endpoints on any given deployment depend on the
    app's own schema and registered queries. The framework repository was
    archived on 2026-05-29 as the team shifted to the Superlinked Inference
    Engine; the server REST pattern documented here reflects the framework as
    last published.

      summary: Ingest records for a schema
      description: >-
        Generated per schema declared in the Superlinked app. Accepts one or
        more records matching the schema's fields; the server computes
        multi-modal embeddings and persists them to the configured vector
        database. The {schema} path segment is the schema's id (for example,
        the lowercased schema class name).
      parameters:
        - name: schema

        Generated per RestQuery registered in the Superlinked app. The request
        body parameters (for example natural_query, limit, and any query-time
        weights or filters) are derived from the query definition. Returns
        ranked entries from the connected vector store, optionally with metadata.
