Tools 80 found in our last check

• request_human_approval

  Ask a named principal for a specific decision using the provisioned voice approval channel. Requires restricted approvals:write, a configured callback host and signing secret. Returns dispatch status; the signed callback carries the decision and evidence. No approval is implied…

• connect_agent

  Connect an external agent to a business and its signed event outbox. Requires current business admin membership, an assigned Kai agent, and agents:write, sms:write, webhooks:write. New SMS/WhatsApp conversations route to the external agent; explicit handoffs win. Grants no addit…

• get_agent_connection

  Discover the external agent connection, signed webhook configuration, scoped API operation catalog, channel readiness and remaining runtime requirements. Requires agents:read, sms:read and webhooks:read. Configuration does not prove delivery or recipient consent.

• disconnect_agent

  Disconnect the external agent and disable its webhook atomically. Requires current business admin membership and agents:write, sms:write, webhooks:write. Pass the stored expected_revision. Inherited conversations return to Kai; explicit handoffs remain.

• get_lsa_account_report

  Read the authorized advertiser's live Google Local Services aggregate account report, including actual spend, currency and charged lead totals. Requires linked manager-account access. Dates are calendar dates inclusive at both ends. Source may lag by 30 minutes. Connected phone…

• get_lsa_setup

  Inspect Google LSA account selection and sync freshness, with setup steps. Saved configuration never proves a live workflow. Cloud-project production access is not shown here; Google Cloud reports it.

• sync_lsa

  Sync an explicitly selected connected LSA advertiser. Requires current business admin role. Syncing runs lead ingestion, and existing business speed-to-lead configuration may contact the new leads it finds.

• list_lsa_leads

  List synced Google LSA leads, charge and credit states, source IDs and rating details. The returned LSA lead id identifies the lead in LSA commands; the separate lead_id field links to the CRM.

• get_lsa_conversations

  Read the latest 200 synced Google LSA conversation events for an LSA lead, including customer and advertiser messages. History is as current as the last sync.

• get_lsa_report

  Report LSA lead counts, types, observed statuses, ratings and credit counts for an explicit UTC window (start inclusive, end exclusive). Includes sync freshness and completeness. Removed unrated leads are counted separately because they cannot be rated here. Financial amounts, s…

• send_lsa_reply

  Send an authorized text reply inside an existing Google LSA message lead through the Ads API. This contacts the customer. Requires current business admin role and a stable idempotency_key. A retry with the same key is deduplicated; pending/unknown writes are blocked. Provider ac…

• rate_lsa_lead

  Submit an authorized, truthful Google LSA quality survey and return Google's actual bonus-credit decision. This is not a guaranteed refund or the retired manual dispute workflow. Requires admin role and a stable retry key. Each rating is a per-lead survey answer based on that le…

• get_callrail

  Read a business's CallRail call-tracking setup. action=status returns the connected CallRail account, which CallRail companies feed which business, every company the saved key can see (with its company_id), and the businesses you can link them to. action=list_trackers (with link…

• manage_callrail

  Connect CallRail call tracking to a business's line. Order: (1) connect {api_key, account_id?}; (2) get_callrail status lists the companies the key can see; (3) link_company {company_id, target_business_id?} once per business; (4) set_writeback {enabled}; (5) get_callrail list_t…

• get_nimbata

  Read a business's Nimbata call-tracking setup: the connected Nimbata account, which Nimbata projects feed which business (with when each last synced and how many calls matched), the projects the saved token can see, and the businesses you can link them to.

• manage_nimbata

  Connect Nimbata call tracking to a business's line. connect {api_token} checks and saves a Nimbata personal API token (Agency plan; one token can serve many businesses). link_project {project_id, target_business_id?} attaches that Nimbata project's calls to a business and adds K…

• agency_profile_bootstrap

  Registers a new agency for the signed-in user and makes them its owner, using the given brand and support details. Requires a signed-in user session with a verified email; an API key cannot create an agency. Repeating it for an agency that already exists does not create a second…

• agency_profile_update

  Replaces the agency brand, support details and requested commercial mode. Requires an agency owner or admin and the current profile revision; a stale revision is rejected. It does not change any published offer.

• agency_profile_invite

  Creates a staff invitation for an email address with the admin, operator or reader role and returns a one-time invite link that expires in 7 days. Requires an agency owner or admin; only the owner can invite an admin. It sends no email; the returned link is delivered by whoever…

• agency_profile_accept_invite

  Joins the agency using the token from an invite link. The signed-in user must have a verified email that matches the invited address, and the invite must be unexpired and not revoked. Accepting the same invite again is a no-op.

• agency_profile_revoke_invite

  Cancels a pending staff invitation so its link can no longer be used. Requires an agency owner or admin. It does not remove anyone who already accepted; revoke_member does that.

• agency_profile_assign

  Gives an active agency staff member access to one client business with the admin or member business role. Requires an agency owner or admin who can manage that client; only the owner can assign an admin staff member. Assigning an existing assignment again changes nothing.

• agency_profile_unassign

• agency_profile_revoke_member

  Removes a staff member from the agency: revokes their membership, all their client assignments, their accepted invites and every API key issued to them through the agency. Requires an agency owner or admin; only the owner can remove an admin, and the owner cannot be removed.

• agency_profile_issue_key

  Creates a new API key for yourself in this agency, limited to the requested scopes, and returns the secret once. Readers cannot get write scopes, only the agency owner can get billing:write, and a delegated key cannot issue a key broader than itself. Each call creates another ke…

• agency_offer_save

  Creates a new offer draft, or replaces an existing draft when offerId and its current revision are given. Requires an agency owner or admin. Saving changes only the draft; clients see nothing until it is published.

• agency_offer_preview

  Builds the publishable manifest and sales kit for an offer draft and returns its fingerprint and revision for publishing. Requires an agency owner or admin. It saves nothing and fails if a package release, variant or claim is not supported.

• agency_offer_publish

  Publishes the previewed offer as a new immutable version and returns its enrollment link. Requires an agency owner or admin, plus the fingerprint and revision from preview; partner-billed offers also need billing collection to be ready. Publishing the same fingerprint again retu…

• agency_offer_archive

  Archives an offer so it can no longer be published or used for new enrollments. Requires an agency owner or admin and the current offer revision. Existing installations are not removed.

• agency_enrollment_start_self_service

  Starts a business owner's own enrollment in a published agency offer, using the business name and intake facts. Requires a signed-in user session with a verified email and an idempotency key; the same key replays the same session. Nothing is installed until the owner approves an…

• agency_enrollment_finish_self_service

  Completes a self-service enrollment after the owner has approved the current intake: creates the client business and queues its package installations, which later configure the business's voice agent. Only the owner who started it can finish it. Repeating it returns the recorded…

• agency_enrollment_owner_save

  Lets the client owner replace the intake facts on their own enrollment link. Requires the owner who claimed the link and the session's current revision. Saving clears any earlier owner approval, so the owner must approve again.

• agency_enrollment_create

  Creates an enrollment session for 1-50 existing or new clients against a published offer version and returns one owner approval link per new client. Requires an agency owner, admin or operator with access to each existing client, and an idempotency key; a replay returns the sess…

• agency_enrollment_save

  Replaces the client entries of an uncommitted enrollment session. Requires the session creator (or an agency owner/admin) and the current session revision. Saving revokes all outstanding owner approval links for the batch, so owners must be sent new links.

• agency_enrollment_preview

  Checks every client in the batch for missing facts, owner approval and payer conflicts, and returns what enrolling would install, with the fingerprint and approval IDs needed to enroll. Requires an agency owner, admin or operator. It records the preview on the session but instal…

• agency_enrollment_enroll

  Commits the previewed batch: creates new client businesses, records owner approvals and queues package installations for every ready client; installations later configure each client voice agent. Requires an agency owner, admin or operator who created the session, its idempotenc…

• agency_enrollment_claim_owner

  Links the signed-in client owner to their enrollment link using its token. The user's verified email must match the owner email on the link. It approves nothing.

• agency_enrollment_approve_owner

  Records the client owner's approval of the exact offer and intake facts on their enrollment link. Requires the owner who claimed the link, the session's current revision and its fingerprint. It does not enroll; the agency still enrolls the batch.

• agency_enrollment_rotate_owner_link

  Issues a new owner link for a client in the batch and invalidates the old one, clearing any earlier claim and approval. Requires the session creator (or an agency owner/admin) and the link's current revision. It sends nothing; the returned link is delivered by whoever re-issued…

• agency_enrollment_revoke

  Revokes an enrollment session and all of its owner links so nothing more can be approved or enrolled from it. Requires the session creator or an agency owner/admin. Installations that were already enrolled are not removed.

• agency_installation_preview_route_receipt

• agency_installation_approve_route_receipt

  Records the client owner acknowledging the route test receipt they reviewed. Requires the client owner who received the notification and the fingerprint from preview_route_receipt. It does not place any call.

• agency_installation_preview_handoff

  Returns the staff handoff for an installation with a fingerprint for approval. Requires client membership or agency assignment to the client. It changes nothing.

• agency_installation_approve_handoff

  Records the client owner approving the exact staff handoff they reviewed. Requires the client owner and the fingerprint from preview_handoff.

• agency_installation_resolve_update

  Chooses, for each conflicting setting in a proposed package update, whether to keep the client's current value or use the package value, and saves the resolved update. Requires the client owner and the update's fingerprint; client facts cannot be overridden this way. It does not…

• agency_installation_run_scenarios

  Run approved verification scenarios for an existing client installation at its expected revision using voice agent compute under existing entitlement. Requires current assigned client authority, current owner approval and evals:write. Saves test evidence and can incur irreversib…

• agency_installation_owner_preview

  Shows the client owner the exact intake facts and voice script prepared for their business, with the hashes needed to approve each. Only the client owner can view it, and only after the agency prepared a complete preview. It changes nothing.

• agency_installation_approve

  Records the client owner approving either the intake facts or the voice script they reviewed. Requires the client owner and the matching hash from owner_preview. It does not install anything by itself.

• agency_installation_revoke_approval

  Withdraws one of the client owner's earlier approvals. Requires the client owner. Work that depends on that approval waits until it is approved again.

• agency_installation_pause

  Pauses an installation so its package setup and scheduled package work stop. Requires agency write access to the client or the client owner, and the current revision. It does not delete anything; use retry to queue it again.

• agency_installation_retry

• agency_installation_export

• agency_installation_preview_offboard

  Shows what offboarding would stop and what it keeps (phone number, sender, connections, billing plan and history), with a fingerprint for approval. Only the client owner can view it. It changes nothing.

• agency_installation_offboard

  Starts offboarding: stops the package's jobs, revokes its future automation authority and turns off its scheduled reports. Requires the client owner, accepted set to true and the fingerprint from preview_offboard. The phone number, connections, billing plan and history are kept.

• agency_installation_preview_update

  Prepares a proposed update to a newer published offer version, or a rollback to an earlier installation revision, and lists any conflicts with client changes. Requires agency write access to the client or the client owner. It saves the proposal for review but does not apply it;…

• agency_installation_approve_update

  Records the client owner approving the updated script of a proposed update. Requires the client owner, the updateId and its fingerprint. It does not apply the update.

• agency_installation_apply_update

• agency_billing_set_plan

  Puts a partner-created client on an agency-billed plan, or stops it when plan is null. Requires the agency owner who is also a client admin; starting a plan needs accepted terms and a ready collection method. Stopping parks the client service, which detaches its phone numbers fr…

• agency_billing_publish_terms

  Publishes a new set of wholesale commercial terms (discount, grace days, document and start date) for one agency, or for all agencies when partnerId is null. Platform commercial operators only. Each call publishes another version; agencies must still accept it.

• agency_billing_accept_terms

  Accepts published wholesale terms for the agency and applies their discount. Requires the agency owner, and the terms must be in effect and apply to this agency. It charges nothing and doesn't set up payment.

• agency_billing_setup_collection

• agency_care_prepare_review

  Saves the approved review-request texts as a draft campaign and reserves the listed customers. Requires the client owner, the sms:write scope, accepted set to true and the fingerprint from preview_review. It sends nothing; launch_review sends it.

• agency_care_launch_review

• agency_support_acknowledge

• get_extra_number_status

  Read an owner-authorized extra-number request. Billing, assignment and live activation are distinct. Unknown checkout or provider outcomes retain the original request and number, so no replacement purchase is needed or started.

• retry_setup

  Reconcile database pointers for an existing imported signup phone reservation. Owner-only, entitlement-checked, single-flight and idempotent. Never creates agents, buys numbers, changes provider routing or sends messages. PBX, missing imports, and stale claims return review bloc…

• get_setup_recovery_status

  Read an owner-authorized setup recovery request by its business and idempotency key. Running requests are never automatically stolen, including stale requests. A ready receipt does not prove live activation.
