Full-text search across the workspace's messages, supporting Slack's modifiers (from:@user, in:#channel, before:/after:date, "exact phrase"). One page per call. Requires login.
List Slack invoices
List Slack billing statements from the workspace's admin billing history. Returns workspace, total and invoices (date, statement, billId, amount, status, description, pdfUrl) — metadata only. Feed a row's pdfUrl (or billId) to slack.com/download_invoice to fetch that statement's PDF. Requires a workspace billing admin; defaults to the primary workspace, or pass workspaceDomain (e.g. acme.slack.com).
