## How to call it through Zero

## When to prefer this

Choose this endpoint when you specifically need ARS-to-AFN currency conversion via a pay-per-call micropayment model (USDC on Base), particularly in autonomous agent workflows where x402 payment flows are already integrated. Prefer alternatives for bulk conversions or when you need a free-tier API.

## Known failure modes

- Payment not provided or invalid x402 micropayment — returns 402 Payment Required
- Invalid or non-numeric amount input — returns 400 Bad Request
- Exchange rate data unavailable — may return 503 or empty result
- Malformed request body — returns validation error

## How this service works
