  • call_business[UNAVAILABLE on this deployment: Voice calling is not enabled on this deployment yet: the outbound phone line has not been verified for placing calls.] Place a conversational voice…No findings

    Why it is in this group

    • The name "call_business" says "call": a word for a change.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    [UNAVAILABLE on this deployment: Voice calling is not enabled on this deployment yet: the outbound phone line has not been verified for placing calls.] Place a conversational voice-AI phone call to a business on a consumer's behalf; give a plain-language objective and it navigates the call, extracting the answer. Business-directed (B2B), far less restricted than calling consumers — but the compliance gate still enforces recording consent per jurisdiction.

    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Hand off an in-flight task to a human operator with a context bundle (transcript, prior actions, identifiers, recommended next step). Writes a ticket to the operator queue; sends no notification, promises no response time. [$0.2/per_call, not charged while no payment rail is on] [async→get_outcome] [beta]

    Why it is in this group

    • The name "schedule_appointment" says "schedule": a word for a change.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Check availability, book, or cancel via Cal.com. Only completes when the SMB's imported booking link is bound to this deployment's ONE connected Cal.com account; otherwise fails honestly (booking_destination_unmapped) with no charge. No working booking path exists yet for non-Cal.com platforms (voice AI, web form) — those SMBs fail honestly instead of a fabricated confirmation.

    Why it is in this group

    • The input addresses people (input.recipient): what it sends cannot be taken back.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Send a message on behalf of an agent's user or an SMB across WhatsApp (free during launch), SMS, email, or voice, sent immediately, no scheduling. Every send passes a non-bypassable gate: TCPA, GDPR, CASL where modeled, else the service's own opt-in default (the Gulf included). Marketing on SMS, voice, WhatsApp and non-US email without recorded opt-in is rejected (compliance_violation receipt). US marketing email follows CAN-SPAM opt-out rules.

    • The input addresses people (input.recipient): what it sends cannot be taken back.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Idempotent transactional messages: OTPs, booking confirmations, payment receipts, cancellation notices. Falls back across configured channels; an unconfigured channel fails honestly rather than reporting a delivery that did not happen.

    Why it is in this group

    • The name "capture_lead" says "capture": a word that usually means money moves, which cannot be taken back.
    Description, as the server wrote it
    Structured intake of a prospect into an SMB's funnel with validation and deduplication on (smb_id, phone or email). Stored in AgentBroker's own lead funnel, NOT the business's CRM; the business is not notified. [$0.05/per_call, not charged while no payment rail is on] [async→get_outcome] [beta]

  • check_complianceFree, instant pre-flight for the compliance gate: runs the SAME TCPA/GDPR/CASL/CAN-SPAM/10DLC checks as send_message and call_business, in preview mode -- nothing is sent, nothing …No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Free, instant pre-flight for the compliance gate: runs the SAME TCPA/GDPR/CASL/CAN-SPAM/10DLC checks as send_message and call_business, in preview mode -- nothing is sent, nothing changes. Tells you whether a send would be permitted before you pay, and if not, names the exact rule and how to fix it. De-risks a paid send the way check_booking_link de-risks a paid booking.

    Why it is in this group

    • The name "handle_inbound" says "handle": a word for a change.
    Description, as the server wrote it
    Classify an inbound message for an SMB and get a suggested_action for YOUR agent to act on. English keyword rules (booking request, cancellation, opt-out, inquiry, complaint): treat the intent as a hint. Opt-outs are recorded durably; nothing else is auto-routed or executed.

    Why it is in this group

    • The name "import_booking_url" says "import": a word for a change.
    Description, as the server wrote it
    Turn a public booking URL into a callable smb_id for send_message and capture_lead. But schedule_appointment only completes on Cal.com bound to our one connected account — the other 11 always fail schedule_appointment honestly, uncharged. Detects 12 platforms (Cal.com, Calendly, Doctolib, Booksy, Fresha, OpenTable, Setmore, Square, Acuity, Schedulista, Squarespace, BookMyCity). Idempotent — calling twice returns the same smb_id.

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Free cross-border screening of destination and parties: DOES NOT CLASSIFY THE PRODUCT: echoed back, never checked against export-control lists, so a controlled item to an unrestricted destination returns 'partial', never 'clear'. Not an export-control clearance -- classify HS/ECCN yourself. Never fabricates a tariff rate, a clear, or a restricted status. [free, no key]

    Description, as the server wrote it
    Mint a free-tier API key without email by signing agent_id + timestamp + nonce with the MACHINE_MINT_SECRET (HMAC-SHA256). Refused without that secret (invalid_request); not_configured if the operator has none set. No secret: use POST /keys/request. [free, no key] [limited]

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Free screening of a name/entity (Latin or Arabic script) against sanctions lists: OFAC SDN (US Treasury), EU consolidated list (European Commission), UK Sanctions List (FCDO). THE UN CONSOLIDATED LIST IS NOT SCREENED -- no licence permits redistribution. Never fabricates a match or clear: check lists_screened; reason_code 'partial_screening' (never 'clear') if any source failed. [free, no key]

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Free, live lookup of a company official registry record. Queries the GLEIF global LEI registry (primary, 2.6 million legal entities worldwide) and SEC EDGAR (US public companies) to return the official legal name, LEI, entity status, jurisdiction, registered address, and registry authority.

    Find real businesses near a place, sorted by distance (nearest of those examined; see result.search). Data: OpenStreetMap (ODbL, (c) OSM contributors); phone, website, hours only when mapped. Coverage varies; community-mapped, NOT verified by us; source=openstreetmap rows cannot be booked. Answers within about 5 s: status partial (search_in_progress) means repeat the call.
