## 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-fx-quote-ars-to-usdc-c53122a8
```

Example prompt: I need a LupaPago FX quote to see how much USDC I'd get for 100,000 Argentine Pesos — just the ticket, not an actual settlement.

## When to prefer this

Use this endpoint when you need a quick ARS-to-USDC conversion estimate using LupaPago's fx-quote-v1 ruleset, especially within Argentine payment workflows or before initiating a full x402 USDC settlement. Prefer this over live-market FX endpoints when a stub/reference rate is acceptable for budgeting or UI display. Do not use when you require actual on-chain settlement or a live interbank rate.

## Known failure modes

- Invalid or missing amount_ars (non-integer or centavo values rejected — whole ARS only)
- Negative or zero ARS amount
- Payment not provided or incorrect (endpoint costs $0.02 USDC via x402)
- Rate is a fixed stub (1400 ARS/USDC) and does not reflect live market — stale rate risk
- No settlement occurs — callers expecting on-chain execution will be disappointed
