## 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 agent-micro-payment-decision-procedure-3b2b9504
```

Example prompt: Before my agent pays this $0.05 x402 request from a merchant with a trust score of 0.8 and $2.30 remaining in my daily budget, walk me through the decision procedure — should it auto-pay, deliberate, defer, or escalate?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically evaluate a single x402 or MPP payment request against its standing policy before executing payment. It is especially useful when building payment-gated agentic workflows that require auditable, policy-driven authorization logic rather than hardcoded thresholds. Prefer this over generic spend-guard logic when you need structured failure modes and numbered decision steps compatible with the x402 protocol.

## Known failure modes

- Missing or expired quote causes inability to assess freshness
- Merchant trust score unavailable returns incomplete decision path
- Budget data stale or unavailable leads to conservative deferral recommendation
- Malformed input parameters return an error payload with ok=false

## How this service works

Decision procedure for individual agent micro-payments: when to auto-pay, deliberate, defer, or escalate a single x402/MPP payment request. Uses amount vs standing-policy cap, merchant trust score, remaining budget, and quote freshness. Returns numbered decision steps, exit criteria, and failure modes.

## Output

A structured, numbered decision procedure indicating whether to auto-pay, deliberate, defer, or escalate the payment request, along with the specific exit criteria for each branch and a list of failure modes the agent should handle.
