## 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-amd-currency-converter-ac1f93ff -d '<json body>'
```

Example prompt: Convert 500 Argentine Pesos to Armenian Dram for me.

## When to prefer this

Choose this endpoint when you specifically need ARS-to-AMD currency conversion with per-call micropayment pricing via x402/USDC on Base, and you want a self-hosted, low-cost option at $0.0002 per call rather than subscribing to a traditional forex API.

## Known failure modes

- Payment not provided or rejected — 402 response requiring x402 USDC micropayment on Base
- Invalid or non-numeric amount input — may return 422 or error response
- Exchange rate data unavailable — service may return an error or empty result
- Endpoint unreachable — network or hosting downtime on api.fastapi.online

## How this service works

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