Is There a Third-Party Way to Check Sam's Club Inventory? Yes, Club by Club Through an API

Yes. Scavio's Sam's Club API checks stock club by club: POST /api/v1/samsclub/product with an item_id and a club_id returns whether that club has the item on the shelf (in_stock_at_club), the aisle, its shelf price, and a separate status and quantity for pickup, delivery and shipping. /api/v1/samsclub/clubs turns a ZIP code into the nearby club ids, so one loop covers every club around you. Each call is 1 credit, about $0.002 on the Growth plan billed yearly, with no Sam's Club membership.

The question comes from r/samsclub, where a member asked whether any third-party app can look up Sam's Club stock the way people do for Walmart and Costco, because the club's own app had been "notoriously incorrect", even for a full pallet in front of them. It was the first result when we searched Google for Reddit threads on checking Sam's Club inventory. No third party sees the shelf directly, but there is a way to read each club's published stock without the app, and to read it for several clubs at once.

What an API can and cannot fix

Scavio reads the stock samsclub.com publishes for a club when you call, so it is not more accurate than Sam's Club's own record: if a club's count is wrong, the response is too. It does three things the app makes hard:

• Every nearby club at once. One call per club, in a loop, instead of switching your home club in the app.
• Stock per method. Pickup, delivery and shipping each come back with their own status, so "out of stock" at the club is not confused with "ships to your door".
• Not carried vs out of stock. If a club does not carry an item id, the call returns not found instead of a misleading stock flag.

Step 1: Get the club ids near you

curl -s https://api.scavio.dev/api/v1/samsclub/clubs \
  -H "Authorization: Bearer $SCAVIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"zip": "33130", "limit": 3}'

ZIP 33130 in Miami returned club 6217, "Miami Sam's Club" in Doral, at 7.97 miles, then Miramar (8173) and Sunrise (6341). Each row has the address, phone, hours and a temporarily_closed flag.

Step 2: Ask each club for the item

curl -s https://api.scavio.dev/api/v1/samsclub/product \
  -H "Authorization: Bearer $SCAVIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"item_id": "13636265340", "club_id": "6217"}'

Item 13636265340 is the BODYARMOR Sports Drink Variety Pack, 24 pk. We asked six clubs for it on October 31, 2026. The Doral answer, trimmed to the stock fields and the pickup option:

{
  "price": 16.48,
  "club_price": { "price": 16.48, "was_price": null, "savings_amount": null, "unit_price": { "price": 0.057, "display": "5.7 ¢/fl oz" } },
  "club": { "club_id": "6217", "city": "Doral", "state": "FL", "zipcode": "33126" },
  "in_stock_at_club": true,
  "aisle": "F30",
  "fulfillment": {
    "pickup": true,
    "delivery": true,
    "shipping": true,
    "options": [
      {
        "method": "pickup",
        "available": true,
        "availability_status": "IN_STOCK",
        "available_quantity": 8,
        "max_order_quantity": 12,
        "location": "Miami Sam's Club",
        "aisle": "F30",
        "estimated_date": "2026-10-31T17:00:00.000-04:00",
        "fee": null
      }
    ]
  }
}

The Dallas, Greenville club, same item, same hour:

{
  "price": 16.48,
  "club_price": null,
  "club": { "club_id": "4925", "city": "Dallas", "state": "TX", "zipcode": "75206" },
  "in_stock_at_club": false,
  "aisle": null,
  "fulfillment": {
    "pickup": false,
    "delivery": false,
    "shipping": true,
    "options": [
      {
        "method": "pickup",
        "available": false,
        "availability_status": "OUT_OF_STOCK",
        "available_quantity": null,
        "max_order_quantity": null,
        "location": "Dallas, Greenville Sam's Club",
        "aisle": null,
        "estimated_date": null,
        "fee": null
      }
    ]
  }
}

Out of stock for pickup in Dallas, still shipping, and on the shelf at the other five clubs we asked, in aisles F12 (Cicero), B99 (South Gate), F30 (Doral), F16 (Atlanta) and F99 (Tempe).

Step 3: Loop over your clubs

import requests

API_KEY = "sk_live_your_key"  # load from your secret store in real code
H = {"Authorization": f"Bearer {API_KEY}"}
BASE = "https://api.scavio.dev/api/v1/samsclub"

clubs = requests.post(f"{BASE}/clubs", headers=H, json={"zip": "75201", "limit": 5}, timeout=120).json()["data"]["clubs"]
for club in clubs:
    r = requests.post(f"{BASE}/product", headers=H,
                      json={"item_id": "13636265340", "club_id": club["club_id"]}, timeout=120)
    if r.status_code == 404:
        print(club["name"], "does not carry this item")
        continue
    p = r.json()["data"]
    pickup = next(o for o in p["fulfillment"]["options"] if o["method"] == "pickup")
    print(club["name"], p["in_stock_at_club"], pickup["availability_status"],
          pickup["available_quantity"], p["aisle"])

Reading the answer

Two patterns from our checks match what the Reddit thread describes. Fresh items carry regional ids: the Member's Mark whole milk gallon priced in Dallas, Doral and Atlanta came back not found at Cicero, South Gate and Tempe, so an item can "not even show up" for one club while it sits on another's shelf. And clearance runs out fast: the clearance category listed 138 items at the club Sam's Club picked for the call, and 26 of the 42 on the first page were already out of stock.

What it costs

Checking 30 items at your 5 nearest clubs once a day is 150 calls, about 4,500 credits a month: $9 on the Growth plan billed yearly, and not-found answers are free. Stock moves during the day, so check close to when you plan to go. For prices as well as stock, the same calls return the club's shelf price next to the online one; the best Sam's Club product data APIs compares that across six clubs, and how to get Sam's Club product data covers search, Instant Savings, clearance and reviews.
