get_cancel_reminder

Calendar reminder for the last safe day to cancel. Returns a calendar file (.ics) with an all-day event on the cancel-by day, the steps and the official link, with alerts at 9am the day before and 9am on the day. Nothing is stored. get_cancel_steps gives this link as add_to_calendar whenever renews_on is given and the day hasn't passed.

Discovered
get_cancel_steps

How to cancel one subscription. For requests like "how do I cancel Netflix?", "cancel my Planet Fitness membership", "how do I leave Sky?", "cancel my PureGym", "what's the cheapest way to keep Spotify?", "stop my Audible". Returns the official page, steps, catches and a cheaper option. UK answers add region ("UK") and uk_rules; a US-only service asked about from the UK has region "US only".

Discovered
identify_charge

Which subscription is this charge? For requests like "what is this APPLE.COM/BILL charge?", "I see AMZN Digital on my statement", "what is DD *DOORDASH DASHPASS?". Returns the likely service, or for Apple, Amazon, Google and Microsoft the few it could be and where to check, or match: purchase when it looks like a one-off order (marketplace, a ride, a restaurant through a delivery app). Then call get_cancel_steps.

Discovered
