Sharpe Nova OS – Decision Context Packet
x402
Sharpe Nova OS – Decision Context Packet is a paid API for AI agents from nova-retail-controlled-proof.onrender.com, paid per call via x402, $1/call, status unknown (last checked 2026-10-11).
Returns a structured pre-execution decision-context packet for an agent-prepared capital action, capturing state, boundary effects, and integrity digests without approving or executing the action.

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
A JSON decision-context packet containing: unique packet_id, created_at timestamp, boundary effects (approval, execution, authorization, chronology acceptance — all 'none'), integrity block with sha256 packet and content digests and trust semantics, portability metadata indicating no vendor session dependency and intended cross-system use cases, authority handoff describing decision and execution owners, governed review context with source state and resource ID, access effect, resource type, schema version, and a limitations array clarifying the packet does not approve, authorize, or execute the action.
Example use cases
Pre-trade review packet for equity action
“I have an agent-prepared buy order for 500 shares of AAPL ready to go — can you generate a Nova decision-context packet for it so I can send the full review context, boundary effects, and integrity digests to our compliance desk before anything gets executed?”
Cross-system handoff after wallet change
“Our custodian just changed and I need to hand off a pending capital action to the new system — can you fetch a portable Nova decision-context packet for this action that doesn't depend on any vendor session so the new execution provider can pick it up cleanly?”
Audit trail digest for governance records
“We need a deterministic content digest of this agent-prepared transaction for our audit log — can you get a Nova decision-context packet with the sha256 packet and content digests so we have a verifiable record of what the action looked like before any authority reviewed it?”
Technical details
Endpoint
POSThttps://nova-retail-controlled-proof.onrender.com/retail/v1/context/decision-packet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a portable, integrity-stamped decision-context packet before submitting a capital action for institutional review — especially when the action may cross system boundaries (agent change, wallet change, custodian change) and a vendor-session-independent artifact is required. It is the right choice when you need deterministic content identity digests for audit purposes without any approval, execution, or authorization side effects.
Side effects
- Missing or malformed action payload returns 4xx with validation error
- Payment of 1 USDC not received via x402 protocol results in 402 Payment Required
- Upstream state source unavailable causes incomplete governed review context
- Rate limiting or server cold-start on Render hosting causes timeout or 503
- Schema version mismatch between caller and endpoint returns unrecognized fields
