TOOLS

Supported Tools

Every Human Approval - HITL Platform action and event your agent gets out of the box.

Cancel Approval Request

Irreversibly cancel a pending approval request so reviewers can no longer complete it.

Create Approval Request

Create and broadcast one human approval request to active members of an owned loop, consuming one provider request allowance.

Create Loop

Create an approval loop and return its loop ID and human invitation links; the connected account is added as an active member.

Delete Loop

Permanently delete an owned loop and all of its memberships, approval requests, responses, feedback, and analytics.

Get Account Status

Return the connected HITL account identity, status, permissions, and provider-reported request allowance before creating an approval request.

Get Approval Request

Get the current status, configuration, and human response for one approval request; use for deliberate polling after creation.

List Approval Requests

Return approval requests created by the connected API key, optionally restricted to one loop; pagination controls are omitted because the live API currently ignores them.

List Loop Members

Return a loop's active and pending human reviewers so an agent can verify readiness before broadcasting an approval request.

List Loops

Return all approval loops owned by the connected account, including embedded members and membership counts.

Update Loop

Update one or more display fields of an owned approval loop without changing its members or requests.
