A SKU's cost basis — the replacement cost a cost-plus catalog marks up

GET /items/{sku}/cost

A SKU's cost basis — the replacement cost a cost-plus catalog marks up, in the organization's home currency: the latest receive that carried a home-currency unit cost (source: receipt, purchase-order receipts included) or the latest figure set by hand (set), whichever came last.

A kit's is its components' cost bases × their quantities (kit); 404 SkuCostNotFound while a SKU (or any of a kit's components) has none. Not the FIFO average, and never posted: valuation is GET /valuation/:sku. Read-only.

The panel writes this call in other languages. It does not send it: Manifold's APIs do not take calls from a web page on another site, so run the call from your own code or terminal. The whole API as OpenAPI: inventory-manager.openapi.json. Base URL https://inventory.getmanifold.io.

Errors

Every refusal is a status and a JSON body whose _tag names it. A refused call changes nothing.

`401`

Refusal	What it means	What to do
`Unauthorized` reason	The token is missing, expired or not one Manifold issued.	Get a fresh token and send the call again.
`TokenAlreadyUsed` tokenId	A single-use app token was already spent.	Mint a new token for this call.

`402`

Refusal	What it means	What to do
`SubscriptionRequired` status	The organization's subscription has lapsed, so writes are refused.	An owner settles billing. Reads still work meanwhile.

`403`

Refusal	What it means	What to do
`TenantRequired` userId	The token names no organization.	Choose the organization, then get a new token.
`ScopeRequired` required	The token's roles do not grant the scope this call needs.	Ask an owner or admin for a role that grants it.

`404`

Refusal	What it means	What to do
`ItemNotFound` sku	No such record in this organization.	Check the id in the path or the body.
`SkuCostNotFound` sku	A SKU (or any of a kit's components) has none.	Check the id in the path or the body.

`409`

Refusal	What it means	What to do
`MirroredFromSource` source	This area is fed by your source system until the organization goes live.	Make the change in the source system, or go live first.

`503`

Refusal	What it means	What to do
`RequestLogUnavailable` tokenId, reason	The service could not record the request, so it did nothing.	Try again shortly.
