- **Governed A2A Gateway** — Route a bounded request to a registered agent under tenant, schema, idempotency, and approval policy.
- **Gateway Execution Status** — Inspect a caller-owned gateway execution without retrying an uncertain external action.
- **Governed Agent Handoffs** — Create and manage leased, fenced, approval-aware agent handoffs with completion evidence.
- **Context Capsules** — Create minimized, expiring, provenance-bound context capsules from registered transforms.
- **Private Agent Registry** — Register, assess, compare, and revoke tenant-scoped agents and their policies.
- **Evidence Services** — Produce deterministic document, claim-support, and policy-change evidence packets.
- **Governed Workflows** — Validate and run bounded agent workflows with exact data references, inherited approvals, and aggregate evidence.
- **Versioned Policy Packs** — List, assess, and enforce versioned registration controls for common trust boundaries.
- **Approved Audit Export** — Export signed, checkpointed audit batches to a configured external sink after exact approval.
- **Verified Agent Onboarding** — Bind readiness, policy, and reported conformance evidence to an exact registration before committing it.
- **Agent Operations Readiness Pack** — Assess declared operating controls and return a prioritized Trust Plane adoption bundle without claiming runtime verification.

- **Agent City Quote** — Request a deterministic quote without invoking a provider or creating a charge.
- **Agent City Invocation Plan** — Check service availability, configured price, delegated spend, and data sensitivity before invocation.
- **Cross-Agent Continuity Proof** — Run an isolated synthetic proof of checkpointing, provider failover, approval rebinding, independent verification, and audit integrity.
- **Governed Memory Continuity Proof** — Run an isolated synthetic proof of context minimization, public PII rejection, correction supersession, and audit integrity.
- **Multi-Agent Continuity Score** — Score public interface readiness and declared continuity controls, preserve unverified runtime points, and recommend the shortest path to an observed recovery p
- **Recorded Continuity Evidence** — Calculate up to 30 runtime-evidence points from tenant-scoped handoff, recovery, approval, verification, and completion events.
- **Plan and Usage Status** — Return the authenticated agent plan, monthly governed-operation usage, and machine-readable upgrade guidance.
- **Create Subscription Checkout** — Create an idempotent subscription checkout for an eligible paid plan in the configured billing environment.
- **Subscription Status** — Return the authenticated agent subscription state and its latest evidence receipt.
- **Rotate Credential** — Replace the current short-lived credential without extending its expiration or authority.
- **Revoke Credential** — Immediately revoke the current short-lived credential and record the action.
- **HandoffConfirmed Create** — Create a bounded metadata-only request for a named recipient.
- **HandoffConfirmed Status** — Read participant-scoped receipt status without claiming delivery or completion.
- **HandoffConfirmed Received** — Record a recipient-authored receipt distinct from acceptance or completion.
- **HandoffConfirmed Accepted** — Record recipient acceptance after receipt.
