aboutWhat Ringler is, what it costs (it's free), and how your person gets started (sign in once, no card). Call this first if you have no key. (No API key needed.)
statusStart here, every session. Your person's line, agent name, mobile, calendar, balance — and onboarding: an ordered list of questions to ask them (name the agent, mobile, number, booking details, how to reach the agent, calendar, first errand) with the tool that records each answe…
callThe agent dials the number, works the menu, hold and any bot until a real person answers, then rings your person's mobile and connects them. Free, within the daily limit of 60 minutes of calls. If it hits voicemail it leaves a short message with a callback (default on; voicemail…
errandThe agent makes the call and does the asking itself: a reservation, an appointment, a question, a cancellation. It only rings your person if the other side needs them (a card, a decision). Put every detail in `ask` — names, date, time, party size, account — because the agent can…
my_callsRecent calls, newest first: when, who, outcome, summary, whether a transcript exists.
transcriptOne call in full: every line with speaker and time, the summary, and a one-hour recording link.
my_numberYour person's own phone number, answered by their agent. Gets one if they don't have one yet (free), in the area code given or their mobile's. Confirm the area code with them first.
my_mobileThe phone that rings when the agent has someone on the line for your person.
who_can_reach_mePeople the agent puts straight through when they call your person's line; everyone else gets a message taken. Pass `people` to set the list, nothing to read it.
forget_callDelete the transcript, summary, recording and any relayed messages from one call, for good. Only when your person asks. The fact that a call happened, and its cost, remain.
notesThe notes you and your person keep about how they like things: how the phone agent should greet them, what to call them, favorite places, habits, standing preferences. The agent reads them on every call as a guide (dated; later notes refine earlier). Call with nothing to read (r…
my_detailsYour person's full name, email, and address, as the agent gives them to a venue: the name for bookings, the email for confirmations and payment links (never their mobile), the address only when a task needs it. Pass fields to set them; nothing to read. Ask your person before set…
call_atSchedule a call or errand for a time: the office opens at 9 their time, a callback window, tomorrow morning. Same fields as errand/call plus run_at. Work out run_at yourself from the called party's local hours and pass it as ISO 8601 with an offset (e.g. 2026-11-09T09:05:00-07:0…
scheduledCalls waiting to be placed, placed, or failed. Pass cancel: <id> to cancel a pending one.
vibeSet up to take your person's instructions by phone: they call their own line, say what they want, hang up; you loop on my_messages and do it. Call with no arguments to get the loop instructions and current settings. Pass settings to change them, with your person's say-so: verify…
my_messagesInstructions and notes your person left for you by calling or texting their own line. Returns new ones (marks them read). Check this when you start work and whenever they say they phoned something in. Pass all:true for the recent history.
tell_meSend your person a spoken message through their agent. mode 'text' (best default) texts their mobile; 'hold' keeps it until they next call their line; 'call' rings their mobile and the agent reads it aloud. Their reply by text lands in my_messages. Use 'call' only when they aske…
invite_linkYour person's invite link (ringler.io/?via=<their code>), and how many friends have signed in through it. Ringler is free for them too.
voicesThe voices your person's agent can speak with, each described in a few words (British measured, deep American, warm, bright…), and which one is current. Set one with name_my_agent { voice }.
name_my_agentName the agent (Ringo by default; keeping the name counts), pick its voice from `voices`, and set how it answers when your person calls their own line (greeting). Free; change any time. How it opens calls to other people — its name, who it's calling for, and a straight answer if…
calendar_connectA link your person opens to approve Google Calendar, so the agent can offer times and book.
creditsPrepaid balance and recent usage.
buy_creditsA checkout link your person opens to add credits by card ($20–$500).
