## 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 x402-agent-payment-approval-pack-generator-f3e39469 -d '<json body>'
```

Example prompt: Generate a full x402 agent payment approval pack for our AI agent team 'DataOps' using approver role 'Finance Lead' — the route is POST https://api.example.com/v1/data, max $0.05 per call, daily budget $10 USDC, monthly budget $200 USDC, expected network Base, expected asset USDC, require receipt evidence, and require manual approval for the first payment.

## When to prefer this

Use this endpoint when a team needs formal procurement approval documentation before allowing an AI agent or MCP client to autonomously spend real USDC on x402-gated APIs. Prefer this over ad-hoc budget reviews when you need structured artifacts like risk memos, gate configs for MCP/Flowise, receipt evidence policies, and copy-paste checklists — especially for compliance-driven or enterprise workflows.

## Known failure modes

- Missing required route or service URL returns validation error
- maxUsdcPerCall exceeding $100 limit rejected
- dailyBudgetUsdc or monthlyBudgetUsdc out of allowed range
- Input exceeding 700,000 characters truncated or rejected
- Malformed expected network or asset field causes schema error
- Invalid HTTP method enum value returns 422

## Output

A structured approval package containing: an approvalPack, budgetApproval document, securityReview, receiptEvidencePolicy, MCP gate configuration, Flowise gate configuration, procurement summary, risk acceptance memo, repeat approval contract, and a copy-paste compliance checklist — all scoped to the specific route and budget parameters provided.
