## 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 lupapago-ar-dual-stack-readiness-check-425076a7
```

Example prompt: I'm building an Argentine e-commerce store that needs to accept both local ARS installment payments (cuotas) and USD cross-border SaaS billing — can you check if a dual-stack setup with Mercado Pago and Stripe is the right approach and what the recommended configuration looks like?

## When to prefer this

Choose this endpoint when you need a structured, rule-based evaluation of whether an Argentine merchant can or should run ARS/cuotas and USD payment stacks simultaneously. It is specifically useful for Argentine market contexts where Mercado Pago, Stripe, Pago Nube, and other local PSPs interact. Prefer this over generic PSP recommendation endpoints when the core question is dual-stack coexistence and readiness rather than fee comparison or single-PSP selection.

## Known failure modes

- Invalid or missing request body may return 400 error
- Payment required if USDC balance is insufficient (x402 payment protocol)
- Ruleset may be outdated if ar-dual-stack-v1 has been superseded by a newer version
- Network timeout on slow connections
- Unexpected PSP combinations not covered by current ruleset may return incomplete reasoning

## Output

Returns a JSON object with a list of recommended PSPs (e.g. mercado_pago, stripe), an array of human-readable reasons explaining the dual-stack rationale for each PSP, the ruleset version used (ar-dual-stack-v1), and a disclaimer clarifying these are explicit LupaPago rules, not financial advice.
