• list_workspaces

  List the workspaces and effective access tiers in this credential scope.

• get_signal_health

  Diagnostic view of first-party event flow, Meta delivery outcomes, match quality, and reconciliation gaps from Plainrouter stored measurements. Not admissible evidence for spend-affecting proposals. Does not call the Marketing API.

• get_performance

  Admissible proposal evidence: reconciliation meta_reported is the existing Meta-reported conversions count compared with gateway_verified accepted conversions. The separate purchases block shows Meta-reported Purchase counts under the account attribution setting beside…

• get_inventory_metrics

  Read daily Meta metrics beside counted PlainRouter arrivals for mirrored campaigns, ad sets and ads. object_metrics contains account-timezone daily comparisons; unmatched_arrivals is one workspace/window count without unknown IDs. Counts are null when the arrivals store is…

• verify_signal_ingestion

  Verify server-side Signal ingestion by writing one idempotent, identity-free modeled event for the authorized workspace. This confirms ledger receipt but does not count as real arrival evidence or complete onboarding. No spend capability.

• propose-actions

  Propose a batch of budget, status, upload, or creative-duplication actions for the approved ad account. In Ask, every policy-allowed change waits for a person to approve it. In Full, policy-allowed changes run automatically. Rule violations are blocked and shown in the Inbox…

• dry_run_actions

  Preview policy decisions and execution diffs for a proposed Action batch without writing it.

• list_actions

  List proposed actions for the authorized workspace and advertising account.

• get_action_batch

  Get a proposed action batch for the authorized workspace and advertising account. Each action’s counted_evidence contains frozen proposal-time target figures and coverage; null means not captured.

• get_action

  Get one proposed action for the authorized workspace and advertising account. counted_evidence contains frozen target figures and coverage captured at proposal time; null means not captured. The figures inform and never gate.

• get_action_decision_receipt

  Get the persisted decision receipt for an authorized proposed action. Version 3 receipts include counted_evidence frozen at proposal time with account-currency values, coverage and the other-currency exclusion. Existing receipts are unchanged.

• get_action_policy

• actions.rules.list

  List stored performance rules available to this workspace key. This does not evaluate them.

• actions.rules.show

  Read a stored performance rule and its immutable revisions, with author type only.

• actions.rules.create

  Store a performance rule disabled. Enabling requires an explicit update; this never evaluates or proposes actions.

  List judging Tests with their frozen conversion definitions, loser pause candidate status and reason, and observed conversion event choices for the authorized workspace and ad account. Results rank variants only within each Test.

• actions.tests.show

  Read one Test, its frozen conversion definition, stored verdict facts, and loser pause candidate status and reason. Spend per recorded conversion compares variants only within this Test.

• actions.tests.create

  Create a judging-only Test from 2 to 4 ads in one mirrored Meta ad set. Omit the conversion choice to freeze the workspace default. It records a PlainRouter verdict and never creates a proposal or writes to Meta.

• actions.rules.update

  Edit a stored performance rule by appending a revision, or explicitly enable or disable it. This never evaluates or proposes actions.

• launch.creatives.store-from-url
