fulfillable and inbound counts before a decision. For all SKUs, history or trends use query_report_data on rpt_get_afn_inventory_data, which the reporting server refreshes daily — never page through the catalog here. Scope it with seller_skus or seller_sku. Amazon SP-API · getInventorySummaries · GET /fba/inventory/v1/summaries

## Call it

MCP tool call:

```json
{
  "name": "fbaInventory_getInventorySummaries",
  "arguments": {
    "store": "myStore-US"
  }
}
```

Tool API (early access — contact us):

```bash
curl -X POST https://api.sellersheetai.com/api/v1/tools/fbaInventory_getInventorySummaries \
  -H "Authorization: Bearer $SELLERSHEET_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"store":"myStore-US"}'
```

## Arguments

| Name | Type | Required | Description |
|---|---|---|---|
| `store` | string | yes | the store ref `<store>-<CC>` (name-country, e.g. 'myStore-US') — one of get_user_context's store_refs, verbatim. |
| `details` | boolean |  | include inventoryDetails (fulfillable/inbound/reserved breakdown). |
| `seller_skus` | object[] |  | optional list of seller SKUs (max 50) to scope to. |
| `seller_sku` | string |  | optional single seller SKU; ignored when seller_skus is given. |
| `start_date_time` | string · date-time |  | optional ISO 8601, no earlier than 18 months ago — only summaries changed since then; overrides seller_skus / seller_sku, and changes in the inbound quantities are not detected. |
| `next_token` | string |  | the cursor from the previous call's data.nextToken; omit for the first page. |

## Result

- `data.inventorySummaries` — list of per-SKU summary objects.
- `data.nextToken` — cursor for the next page; '' when this is the last.

## Params (Amazon schema)

- details: boolean granularityType*: Marketplace granularityId*: string startDateTime: string sellerSkus: [string] (max 50) — you may specify up to 50 SKUs sellerSku: string nextToken: string marketplaceIds*: [string] (max 1)

## Gotchas

- data.nextToken expires 30 seconds after it is issued; when paging a start_date_time query, pass the same start_date_time with next_token.
