create_credit_payment_linkReturns a page where the user buys Wozapi credits for single lookups and pays with iDEAL. This tool moves no money. Works when the user is signed in to Wozapi, with the connected API key, or with a trial_code that has the user's e-mail address.
add_trial_emailAdds the user's own e-mail address to a trial. The trial grows to 10 addresses in total and the user gets a Wozapi account without a password (they log in with a code sent by e-mail). Only use an address the user typed.
get_account_balanceread-onlyReturns the remaining credits of the user's own Wozapi account. Needs the user to be signed in to Wozapi, or a Wozapi API key on the connection; when neither is there, the client asks the user to sign in first. Read-only and free.
get_address_listread-onlyReturns the status of an address list: trial rows, number of addresses found, price, payment link, progress, and after payment the result rows (at most 50 per call; use offset for more) and a download link for the Excel file. Can wait up to 20 seconds for the trial or the processing to finish.
start_address_listStarts WOZ lookups for a whole list of Dutch addresses, for example from a spreadsheet the user shared. Runs a free trial on 5 addresses, then gives the price of the full list and a payment page for the user. Returns a list_token for get_address_list. Sending the same list again within an hour returns the same list.
get_pricesread-onlyReturns Wozapi prices: credits for single lookups by quantity, the price of an address list by size, and the trial terms. Read-only and free.
lookup_woz_valueReturns the WOZ values of one Dutch address for all available years, with the address as matched. Costs one trial address or one credit per unique address; the same address again within 7 days, an answer without WOZ values and an error cost nothing. For questions about properties, not to assess or profile people. Needs a trial_code unless the user is signed in to Wozapi or the connection has a Woz
create_list_payment_linkReturns the page where the user reviews the trial and the price of the list and pays with iDEAL. This tool moves no money: payment only happens when the user pays on that page. Optionally stores the user's own e-mail address for delivery of the file and the invoice.
start_trialStarts a free Wozapi trial without an account and returns a trial_code. The trial covers WOZ value lookups for 5 unique Dutch addresses, or 10 when the user's own e-mail address is given. Pass the trial_code to lookup_woz_value and start_address_list. Call it once per conversation, and not when the user is signed in to Wozapi or the connection already has a Wozapi API key.
