Wake-up On LAN (WOL) API
/install wol-api
WOL API
Interact with the Wake-up On LAN website via its REST API using curl. There are 2 major features: A catering system, and event registration system.
Step 1 — Resolve credentials
Run these two shell commands to check for environment variables:
echo "${WOL_API_TOKEN}"
echo "${WOL_BASE_URL}"
- If
WOL_API_TOKENis empty, ask the user:"Please paste your API token, or configure the WOL_API_TOKEN environment variable. You can generate one at
/user/api-tokenson the WOL site." - If
WOL_BASE_URLis empty, asume https://wollan.nl as the base url.
Store the resolved values as TOKEN and BASE_URL for use in the commands below.
Step 2 — Dispatch on user intent
Look at $ARGUMENTS and/or the user's message to determine which action to take.
Catering: List products / show the menu
Trigger: $ARGUMENTS contains products, or the user asks what is available / what's on the menu.
curl -s \
-H "Authorization: Bearer $TOKEN" \
"$BASE_URL/api/v1/catering/products"
Present the result grouped by category. For each product show:
- Name
- Price formatted as
€X.XX(response values are in euro cents — divide by 100) - Stock status (
inStock/ out of stock) - Product ID (the user needs this to place an order)
Catering: Place an order
Trigger: $ARGUMENTS contains order, or the user says they want to order something.
Parse items from $ARGUMENTS in the format productId:quantity,... (e.g. order 3:2,5:1 means product 3 qty 2, product 5 qty 1). If no items are provided in $ARGUMENTS, ask the user which products and quantities they want (show the menu first if needed).
Assume a quantity of 1 if the user provides a product or list of products without quantities.
Build the JSON body and POST:
curl -s -X POST \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d '{"items": [{"productId": PRODUCT_ID, "quantity": QUANTITY}]}' \
"$BASE_URL/api/v1/catering/orders"
On 201 Created: show a confirmation with the order ID, items, and total cost (sum of quantity × productPrice for all items, formatted as €X.XX).
Catering: View order history and account balance
Trigger: $ARGUMENTS contains history, is empty, or the user asks about their orders / balance.
curl -s \
-H "Authorization: Bearer $TOKEN" \
"$BASE_URL/api/v1/catering/orders"
Present the account summary as a table:
| Amount | |
|---|---|
| Total spent | €X.XX |
| Total paid | €X.XX |
| Balance (owed) | €X.XX |
| Pending (in progress) | €X.XX |
Then list each order with its ID, date, status, and items. Only show the detailed order list if the user asks for it.
Order status meanings:
accepted— received, being preparedwaiting— queued behind other ordersready— ready for pick-upcomplete— picked up / donecancelled/rejected— not fulfilled
Event registration: Check event status
Trigger: $ARGUMENTS contains eventstatus, or user asks if the WOL registrations are open or not
curl -s \
-H "Authorization: Bearer $TOKEN" \
"$BASE_URL/api/v1/events/zijn-de-inschrijvingen-al-open-of-nie"
Returns: open: true|false, with eventId if true.
Event registration: Register for event
Trigger: $ARGUMENTS contains register, or user asks to register for the next WOL event.
Use "Check event status" to check if registrations are open or not, and if so, use that eventId to register the user with the following call:
curl -s -X POST \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
"$BASE_URL/api/v1/events/{eventId}/register"
The result is a simple success:true
Event registration: Check user registration status for an event
Trigger: $ARGUMENTS contains registration-status, or user asks to check his payment status for his registration for the next WOL event.
Use "Check event status" to check if registrations are open or not, and if so, use that eventId to check the users' registration status with the following call:
curl -s \
-H "Authorization: Bearer $TOKEN" \
"$BASE_URL/api/v1/events/{eventId}/registration-status"
Error handling
| HTTP status | Meaning | Action |

Notes
- All monetary values in API responses are in euro cents. Always divide by 100 before displaying (
250→€2.50). - The
curl -sflag suppresses progress output. Pipe through| python3 -m json.toolor similar if you want to inspect raw JSON. - Tokens are managed at
/user/api-tokens(web UI, requires login). Each token can have a name and optional expiry date.
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install wol-api - After installation, invoke the skill by name or use
/wol-api - Provide required inputs per the skill's parameter spec and get structured output
