## 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 claw-in-a-box-spend-policy-guard-63bac98a -d '<json body>'
```

Example prompt: Before I submit this $45 payment to 'StreamFlix' under the entertainment category, run it through the Claw-in-a-Box spend-policy guard and tell me if it gets an allow or deny verdict.

## When to prefer this

Use this endpoint when you need a real-time pre-spend policy verdict before executing a payment or authorizing a transaction, especially in agentic or automated workflows where enforcing spend rules programmatically is required. Prefer this over manual rule checks or post-hoc auditing when you need an instant allow/deny gate.

## Known failure modes

- Invalid or malformed JSON body returns 4xx error
- Missing required spend fields causes validation rejection
- Policy not configured or misconfigured returns error verdict
- Payment of $0.01 USDC required per call; unpaid requests return 402 Payment Required
- Network timeout may cause no verdict to be returned

## How this service works

Spend-policy verdict for AI agents: POST a proposed spend, get allow/review/deny with the exact rules that fired (per-tx caps, per-agent daily ledger, destination allowlists, time windows) - 'review' can page a human on Telegram for approval before the agent proceeds. Pay per call.

## Output

A verdict object indicating whether the proposed spend action is allowed or denied under the configured policy, along with the matched rule or reason for the decision.
