# variantComponent

query · in the family [Variant component](/reference/variant-component/)

## What it does

Look up one record — a kit recipe line — which component (and how many) goes into a kit variant.

A VariantComponent by id, within the caller's OWN org-group family; requires authentication. A cross-tenant id reads as null (not-found) AND trips the rootId tripwire server-side.

## What happens

Reads only — changes nothing.

## Who may call it

Capability area: **Reading your records** — Looking up and listing the records of your organization.

- Owner
- System Administrator
- Manager
- Associate Manager
- Warehouse Associate
- Sales Associate
- An API key whose scope allows `api:variantComponent`

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | [ID](/types/#scalars) `ID!` | yes | The id of the record. |

## Returns

[VariantComponent](/types/VariantComponent/) — A variant component — ONE bill-of-materials edge: quantity units of a COMPONENT Variant inside a kit/bundle HOST Variant. Parent = the HOST Variant (components die with it). The coupling matrix gates creation: a kit assembles simple component variants ONLY; a bundle groups simple | service | kit (never bundles — acyclic BY TYPE). Composition (host x component) is unique (a live duplicate is CONFLICT/IDENTITY_TAKEN naming the holder); REMOVE = doom (TWO_STATE — history preserved); re-adding mints a NEW record via marker takeover. BUILD/BREAK stock semantics + assembly-mode policy evaluation are consumers of this stored shape.
