Tools as reported by the server

• find_business
  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 w
• verify_business
  Look up what we know about a business in our supply network: contact channels, capabilities, last verification. A DIRECTORY LOOKUP - it does not contact the business. Supply-network ids only, not osm:... ids. [free, no key] [limited]
• send_message write/delete
  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, voi
• send_transactional_confirmation write/delete
  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. [$0.02/per_call, not charged while no payment rail is on] [async
• get_status
  Query the current state of any in-flight async operation by operation_id. [free, no key]
• get_outcome
  Retrieve the final OutcomeReceipt for a completed operation. [free, no key]
• preview_cost
  Return an expected cost estimate, latency estimate, and success-probability estimate for a proposed call before execution. Returns the exact price when it is fixed, and a min/max range when the cost depends on channel or outcome. It does not promise an accuracy percentage - check cost_range. [free,
• self_test
  Service health probe: runs 6 internal checks and reports how many passed. Confirms the server is up and responding - it does NOT probe each tool individually. Use to verify connectivity before production use. [free, no key]
• check_compliance
  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.
• get_conversation
  Read a two-way conversation thread you started: its state, every message exchanged, and how many replies the business has sent. [free, requires key]
