## 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 paybox-one-time-virtual-card-authorization-decision-procedure-cfca425d
```

Example prompt: Give me the blunt decision procedure for when to request a PayBox one-time virtual card versus using a standing balance — I need the per-merchant issuance rules, spend ceilings, card lifecycle steps, and re-request conditions so I can build a decision schema for my payment agent.

## When to prefer this

Choose this endpoint when an agent needs a structured, actionable decision procedure for PayBox one-time virtual card authorization — specifically when building or auditing agent payment logic that must decide between card types, enforce spend ceilings, or automate lifecycle steps. Prefer this over general fintech documentation when you need a blunt, agent-consumable brief rather than marketing material, and when the PayBox virtual card system (not generic card rails) is in scope.

## Known failure modes

- Payment not made — returns 402 with payment instructions instead of the brief
- Invalid or unsupported HTTP method — only GET/HEAD/DELETE accepted
- Topic override not recognized — may return a generic or mismatched procedure
- Service unavailable — K-2SO backend down, no brief returned
- Malformed query parameters — meta or topic values outside allowed enum/type rejected

## How this service works

Paid agent-facing brief on PayBox one-time virtual card authorization procedure: when to request a merchant-specific one-time virtual card instead of a standing balance, per-merchant card issuance, expiry and re-request rules, authorization before payment, spend ceilings per merchant, card lifecycle (issue, use, settle, revoke) · Build a decision procedure or schema for: PayBox one-time virtual card authorization procedure: -0. Blunt decision procedure, not marketing.

## Output

A prose decision procedure brief (and optionally structured procedure fields) covering: the blunt go/no-go rule for requesting a one-time virtual card versus alternatives, per-merchant card issuance conditions, spend ceiling limits, expiry and re-request rules, authorization sequencing before payment, and the full card lifecycle (issue → use → settle → revoke). Also returns metadata like generation timestamp, model used, and service slug.
