Changelog

0.4.1

Payment-card approval flow (Phase 2 of the agent payments plan).

• actionlayer_reply now accepts payment_approved: bool for tickets whose info_request includes payment_status. Users approve a charge against their card-on-file with one call.
• actionlayer_get_task / actionlayer_next_action surface card_brand, card_last4, amount_usd, and payment_status on the info_request payload so an agent can prompt the user with "Approve $X.XX charge on your card ending ?"
• The card PAN itself NEVER crosses the MCP boundary. Operator- side reveal is a separate HTTPS-only endpoint gated by Auth0 + claim-holder check + one-shot semantics. This is by design per docs/agent_payments_plan.md.

0.4.0

Backwards-incompatible — public API taxonomy changed.

• Ticket state collapses the in-flight phases (queued, planning, executing, blocked_on_operator) into a single public value pending. Polling code that branched on the individual sub-phases (e.g. if state == "executing") must switch to state == "pending". Terminal states (completed, failed, cancelled) and blocked_on_user are unchanged.
• live_view_url is no longer returned by the public tools (actionlayer_invoke_action, actionlayer_get_action_ticket). It was an operator-side handoff URL; user-facing callers should drive the task via polling actionlayer_get_action_ticket and responding to blocked_on_user prompts.
• actionlayer_invoke_action sync response now uses outcome="queued" (instead of outcome="blocked") when the task escalated to an asynchronous queue (operator pickup, long-running browser run). Callers handling outcome need to add a queued branch: poll actionlayer_get_action_ticket.
• Terminal tickets now carry a free-text reason field summarising the outcome (derived from result.summary on completed, error on failed). Pre-existing result / error fields preserved for callers that want the raw structured payload.

0.3.1

• Update default API URL to https://api.actionlayer.io (api.action-layer.dev still redirects, but the new host is the current canonical name).

0.3.0

• Browser-only catalog. Human-in-the-loop credentials.

0.2.0

• Async-by-default dispatch for browser actions + ticket polling tool.

0.1.0

• Initial release.
