## 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 shared-virtual-wallet-budget-arbitration-procedure-af73b38c
```

Example prompt: Give me the decision procedure for how our agent fleet should handle shared virtual wallet budget arbitration — specifically covering how to reserve spend before payment, detect race conditions when two agents claim the same remaining cap, apply priority tiers, and reconcile settled, failed, and swept-back funds within one wallet cycle.

## When to prefer this

Choose this endpoint when building or operating a multi-agent fleet that shares a single capped virtual wallet and needs a concrete, authoritative arbitration procedure for spend reservation, race condition handling, priority tiers, and end-of-cycle reconciliation. Prefer it over generic budget documentation when you need an agent-executable decision procedure specifically for x402-based payment flows.

## Known failure modes

- Missing or malformed 'input' object returns a validation error
- Payment not included results in HTTP 402 response requiring x402 payment of $0.002 USDC
- Invalid method (e.g. POST) returns method-not-allowed error
- Topic override that is too vague may yield a generic or off-target procedure
- Service temporarily unavailable returns a non-ok response with error detail

## How this service works

Operational procedure for multi-agent fleets sharing one capped virtual wallet: reserving spend before payment, detecting race conditions when two agents claim the same remaining cap, applying priority tiers for arbitration, and reconciling settled, failed, and swept-back funds within the same wallet cycle.

## Output

A structured response containing a prose decision procedure ('brief') and optionally a 'procedure' field, covering reservation logic, race condition detection, priority-tier arbitration, and fund reconciliation steps. Also includes the topic, service slug, ISO-8601 generation timestamp, and generation source (llm, reasoning, or deterministic).
