Send a WhatsApp notification to the account owner's own phone.

text is the message (1-1024 chars). image_url (optional) is a public https image link — a screenshot, chart or diff — delivered as an image with text as the caption when the user's 24h window is open (otherwise text only). Returns a confirmation with the queued message id; raises an actionable error on quota/auth.

Show the pingwa account's plan, remaining monthly quota, and whether the free 24h WhatsApp reply window is currently open.

Get a link to upgrade the account to Pro (raises the monthly quota).

Returns a Stripe Checkout URL for the human to open and pay — no pingwa password needed, the card is handled by Stripe. If the account is already Pro, returns a billing-portal URL to manage or cancel instead.

Ask the human a question on WhatsApp and BLOCK until they reply (or timeout).

text is the question. buttons (optional, up to 3) render as tappable reply buttons; omit them to invite a free-text answer the human types on their phone — use this to let the human steer you mid-task. timeout is seconds to wait (max 90). Returns the human's reply (free text and/or the chosen option). On timeout, returns a note — the question was delivered and the answer is still retrievable via check_replies.

Pull inbound WhatsApp messages the human sent to pingwa (out-of-band instructions, or late answers to an ask). since is a cursor from a previous call (pass it back to get only newer messages); wait long-polls up to that many seconds for something to arrive. Returns the messages and a new cursor.
