# Sharpe Nova OS – Decision Context Packet

> 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 to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sharpe-nova-os-decision-context-packet-7a485e86 -d '<json body>'
```

Example prompt: Before I submit this buy order for review, pull a Nova decision-context packet for it — I need the boundary effects, authority handoff details, and integrity digests so I can hand it off to the local authority for sign-off.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
