## OpenAPI

````yaml https://www.merchkit.com/api/v1/openapi get /openapi
openapi: 3.1.0
info:
  title: Merchkit API
  version: 1.0.0
  description: >-
    Operate your Merchkit PIM programmatically. Products, images, vendors,
    categories, and data sources are all "entities" in one uniform shape: system
    fields (`id`, `type`, `label`, `parent_id`, timestamps) at the top level and
    every customer-defined key — scalars AND references — in a sparse
    `attributes` map. References read as labeled stubs `{id, type, label}` and
    write as bare UUIDs or `{id}` objects ("write what you read"). UUIDs are the
    only path identifiers; find by your own key with a filter (`GET
    /products?filter[sku]=ARIA-DT-72`) or write by it with `POST
    /{resource}/upsert` and `/batch` (products, images, vendors, and categories
    only — sources have neither route; they are created by the async `POST
    /sources` job pipeline). Start every integration with `GET
    /attributes?type=product` to learn your keys. Completeness is per-channel.
    All errors share one envelope (see the `Error` schema). Authenticate with a
    workspace-scoped API key: `Authorization: Bearer mk_live_...`. See /llms.txt
    for an agent guide.
