## 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 x402-ai-gateway-ars-to-aed-currency-converter-01ec156b -d '<json body>'
```

Example prompt: Convert 5000 Argentine pesos to UAE dirhams for me.

## When to prefer this

Choose this endpoint when you need a programmatic, pay-per-call ARS-to-AED currency conversion without a subscription, particularly in agent workflows that already handle x402 USDC micropayments on Base. Suitable for low-volume, on-demand lookups where per-call billing at $0.0002 USDC is acceptable.

## Known failure modes

- Payment not submitted or invalid x402 micropayment header → HTTP 402 Payment Required
- Amount field missing or non-numeric → validation error or unexpected result
- Exchange rate data unavailable or stale → potentially incorrect conversion result
- Network timeout on self-hosted endpoint → no response or 5xx error
- Zero or negative amount input → undefined or zero output

## 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 Argentine Peso (ARS) to UAE Dirham (AED), based on the input amount provided. The exact response schema is loosely typed but expected to include the result of the conversion.
