## When to prefer this

Choose this endpoint when you need real-time FX rates specifically for Latin American or broader emerging market currencies (BRL, MXN, ARS, COP, CLP, PEN, etc.) and want pay-per-query pricing via USDC on Base via x402 — ideal for agents that need FX data on demand without a subscription, or that operate in crypto-native payment environments.

## Known failure modes

- Invalid or unsupported currency code returns an error or omits that currency from results
- Network timeout from Render.com cold-start if service is idle
- Payment failure via x402 if USDC balance is insufficient or Base network is congested
- Missing 'monedas' param returns rates for a default set or all supported currencies
- Stale rates if underlying data source is delayed
