## 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

Example prompt: Convert 2500 Argentine pesos to Costa Rican colones for me.

## When to prefer this

Use this endpoint when you specifically need to convert Argentine Pesos (ARS) to Costa Rican Colones (CRC) and are operating within an x402-enabled micropayment workflow on Base/USDC. Prefer this over general forex APIs when already integrated with the fastapi.online x402 gateway ecosystem.

## Known failure modes

- Payment not included or rejected — returns HTTP 402 requiring x402 USDC micropayment on Base
- Invalid or missing amount field — may return validation error
- Amount of zero or negative value may cause unexpected results
- Service downtime on self-hosted infrastructure — 503 or timeout
- Exchange rate data unavailable — may return error or stale rate

## How this service works

Self-hosted AI API gateway. Expensive endpoints require an x402 micropayment (USDC on Base) before executing.

## Output

Returns the converted currency value representing the input ARS amount expressed in Costa Rican Colón (CRC), likely including the converted amount and possibly the exchange rate used.
