How this service works
Pre-execution decision context for agent-prepared capital actions. State Ping is the front door into a four-stage context ladder. Nova structures review context; local authority decides; external systems execute. Nova does not approve or execute the action.
Output
Returns a JSON object containing the governed review context resource, including: boundary effects (approval, execution, authorization, chronology acceptance — all typically 'none' since Nova does not approve or execute), source state with observed-at timestamps and reconciliation status, temporal context with the intended action window and pending state, authority handoff identifying local institutional authority as decision owner and external system as execution owner, constraint context sources, chronology context with prior review references, and a reproducibility record with context hash and review profile identifiers.
Example use cases
Pre-trade treasury review for agent
“We're about to have the agent execute a large USDC allocation for the treasury desk — can you pull the current Nova governed review context for the action window from 2pm to 3pm today so the desk can review constraints and source state before giving the go-ahead?”
Compliance context check before capital action
“Before the compliance team signs off on today's market-pair position change, retrieve the governed review context from Nova so they can see the boundary effects, source reconciliation status, and chronology references tied to this action.”
Freshness and authority state verification
“I need to confirm that the review context for our pending capital action is still current and that source conflicts are resolved — can you fetch the Nova governed review context and show me the context state value, temporal conflicts, and authority handoff details?”
Technical details
Endpoint
POSThttps://nova-retail-controlled-proof.onrender.com/retail/v1/context/governed-review?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent has prepared a capital action and needs structured pre-execution review context before a human or institutional authority makes the go/no-go decision. It is specifically designed for the Nova OS four-stage context ladder where Nova structures review but does not approve or execute — prefer this over generic state-check or approval APIs when you need reproducible context hashes, authority handoff metadata, constraint sources, and temporal action windows in a single governed response.
Side effects
- Invalid or missing review profile ID returns an error or unresolvable context
- Stale or unresolved source conflicts result in context_state value other than 'current'
- Network or service unavailability on the onrender.com host returns a 5xx error
- Malformed POST body results in a 4xx validation error
- Payment of 0.1 USDC not attached or invalid causes x402 payment-required rejection
