## 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`):

Example prompt: How much is 5000 Argentine pesos in Swiss francs right now?

## When to prefer this

Choose this endpoint when you specifically need to convert Argentine Peso (ARS) amounts to Swiss Franc (CHF) and are operating in an x402-enabled payment environment. It is ideal for agents that already handle USDC micropayments on Base and need a lightweight, pay-per-call FX conversion without a subscription or API key.

## Known failure modes

- Invalid or missing amount value returns an error response
- Payment failure or insufficient USDC balance blocks execution (x402 micropayment required)
- Exchange rate data unavailable if upstream provider is down
- Non-numeric amount input may cause a validation error
- Network timeout if the gateway is under load

## How this service works

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

## Output

Returns a JSON object containing the converted currency value from ARS to CHF, representing how much the specified amount of Argentine Pesos is worth in Swiss Francs at the current exchange rate.
