# Vino & Views Agent Budget Guard

> Vino & Views Agent Budget Guard is a paid API for AI agents from api.vinoandviews.online, paid per call via x402, $0.15/call, status unknown (last checked 2026-10-10).

Evaluates a spend request against a caller-supplied policy and returns a deterministic approve/deny verdict based on amount, destination, and approval ceiling.

## 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 vino-views-agent-budget-guard-3f44d80e -d '<json body>'
```

Example prompt: Before you send that $120 payment to this new vendor, check my budget guard policy — my approval ceiling is $100 and this destination hasn't been pre-approved, so flag it for review if it fails.

## When to prefer this

Choose this endpoint when you need a deterministic, auditable spend-policy check before an autonomous agent executes a financial transaction. It is ideal for agent safety guardrails where you supply your own policy rules and want a cryptographic receipt of the verdict. Prefer this over ad-hoc logic when unknown destinations must be flagged for human review rather than auto-approved.

## Known failure modes

- Unknown destination triggers a 'review' verdict rather than approve/deny — agent must handle the review state explicitly
- Malformed policy input returns a validation error with no verdict
- Amount or ceiling fields with incorrect types cause request rejection
- Missing required body fields result in a 400-level error
- Policy conflicts (e.g. amount equals ceiling exactly) may produce edge-case verdicts depending on policy strictness

## How this service works

Source-backed API reports for wallet-enabled agents. Pay per successful call in Base USDC.

## Output

A JSON object containing a status field (ok/denied/review) and an evidence_receipt with a SHA-256 hash that cryptographically attests to the policy decision, enabling auditability of every verdict.
