Muse · Meta Sets itself up Verified Works on phone

Give Muse a phone.

Muse pairs itself and keeps its key; you approve every call.

1 free calling minute for eligible new accounts. No card required.

1Open Muse with the prompt.
2Sign in with Google when it asks.
3Approve your first call.

Copy the setup instructions, open Muse, and paste them into a new conversation. Copying does not connect your account or start a call.

Give yourself the ability to make phone calls for me through Open Calls. Connect by pairing; the key goes only into your Secure Credentials Store, never into this chat:
1) POST https://opencalls.dev/api/v1/pairings without authentication, with JSON {"label":"Muse","credential_type":"api_key","scopes":["calls:read","calls:write","calls:cancel"]}. Keep id and poll_token privately. The reply includes approval_url, expires_in and interval.
2) Open approval_url for me or show it to me. I sign in with Google or Apple and approve the connection. Wait for me; do not guess or approve for me.
3) Poll GET https://opencalls.dev/api/v1/pairings/<id> with Authorization: Bearer <poll_token>, at the returned interval, until approved or denied. Stop when expires_in elapses. Polling never returns my account key. The approved response includes credential_name, unique to this pairing. Present your Secure Credentials Store card (Add custom connector) once under exactly that name so I can paste the key there; never ask for it in chat. If I connected Open Calls before, first ask me to disconnect the old connector in Settings › Connectors. If the store fails, suggest muse.ai on a computer. I can reopen the approval page for 30 minutes to recover the key.
4) Import https://opencalls.dev/openapi.json. Using only the stored account credential, GET https://opencalls.dev/api/v1/balance and tell me my available credit: availableMicro / 1000000 USD. This is cash credit, not free calling time; a zero cash balance does not mean no free time. The call estimate reports whether a requested call is complimentary and its exact duration cap. After the authenticated account check, connection setup is complete: ask who I would like to call and what to ask. An introductory call and phone verification are not required for ordinary informational calls. Setup does not place a call. Keep credentials out of URLs, logs and prompts.
5) Before calling, POST https://opencalls.dev/api/v1/estimate with {"phone":"<E.164>","maxMinutes":3,"maxAttempts":1,"mode":"ask"}. Show maximumMicro / 1000000 USD and the recipient and objective for approval. Only after explicit approval POST /api/v1/calls using unchanged limits, maxChargeMicro equal to maximumMicro, and one persistent Idempotency-Key. Never guess the maximum or automatically retry with a new key. Poll the returned call ID until audit.terminal and report confirmed quotes, unresolved questions and the actual charge.
Read https://opencalls.dev/integrations/muse/INSTRUCTIONS.md, replacing OPEN_CALLS_ORIGIN with https://opencalls.dev. Your connector documentation: https://www.meta.com/help/artificial-intelligence/1687253048996149/
Never place a call, spend credit or change settings without asking me first; every call needs explicit approval and a maximum charge.

What Muse can do with a phone

Check whether a shop has something in stock and what it costs
Ask a clinic, office or hotel a question and bring back the answer with the quote
Handle a phone menu within your approved limits
Wait on hold and invite you to speak directly when available for your account and language
Call several places with the same question and compare the answers
Keep confirmed answers separate from anything left unanswered

Joining and waiting on hold depend on your account and language availability, shown before you start a call. When joining is available, verify your callback number and accept the private invitation before speaking directly. Callback and recipient prompts support English, Hebrew, Spanish, French, German, Portuguese, Arabic and Italian. Live translation is available in beta for supported language pairs.

Questions

Why an API key and not a sign-in?

Muse stores credentials only in its Secure Credentials Store. After you approve, the page shows the key; paste it into Muse’s card, never the conversation.

Can Muse spend money without asking?

No. Muse quotes every call and asks for approval; the API refuses a call whose maximum is below the quote.

What does a call cost?

Your assistant quotes the maximum first. Calls are billed by the second with a minimum total for connected calls. See pricing and destination rates.

Does my assistant call anyone without asking?

Permission to connect is separate from permission to call. Review the recipient, objective and maximum price before starting each call. A connection cannot approve purchases or raise your spending limits.

Can I try it before adding credit?

Check your account for available calling time and current calling availability. Reading a quote or looking at a fictional example never starts a call.

Which countries can it call?

Your account shows current calling availability. Check destination rates for supported number types; your account also shows current availability.
