Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Check price and availability” would look like.

Example request
curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "www.johnstonesupply.com/check_price_and_availability",
    "input": {
      "part_numbers": [
        "A12-345",
        "NW-4410"
      ]
    }
  }'
Example response
{
  "status": "completed",
  "data": {
    "items": [
      {
        "johnstone_part_number": "A12-345",
        "manufacturer_part_number": "AC-77210",
        "short_description": "Run capacitor, 45/5 MFD, 440V",
        "attributes": "Round, dual",
        "customer_part_number": "CAP-455",
        "price": 18.42,
        "availability": "In stock"
      }
    ],
    "count": 1,
    "currency": "USD"
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

Johnstone Supply’s own options

Johnstone Supply has no public API. Through your local store it offers JS Connect, which sends orders from your own system into Johnstone's, and ServiceTitan Procure-to-Pay, which exchanges purchase orders and invoices inside ServiceTitan. Price and availability are on johnstonesupply.com once your store enables your account.

Signing in to Johnstone Supply

You request a johnstonesupply.com account by choosing a store, and that store verifies your details and enables it.

With Fous you sign in once through the site's own sign-in with your own account, and the login is sealed with AES-256.

Worth knowing

Prices and stock are your store's
Price and availability on johnstonesupply.com are those of the local store you identify when you sign in. A method returns what your store shows, so run it with the account of the store you buy from.
Your store enables the account
Johnstone Supply is wholesale only and asks every purchaser for identification. Your local store verifies the account request and then enables the account.
Quotes come from the store
A quote starts with a quote number from your Johnstone Supply store. Find Quote retrieves it and takes you to checkout.
Product Lists export to Excel
A saved Product List can be exported to Excel, emailed, printed or priced with Retrieve Pricing, and Quick Order puts the whole list in the cart for review.
