## 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-fx-aoa-to-uah-currency-converter-347505f5 -d '<json body>'
```

Example prompt: Can you convert 250 Angolan Kwanza (AOA) to Ukrainian Hryvnia (UAH) for me?

## When to prefer this

Choose this endpoint when you need AOA-to-UAH currency conversion in an x402-enabled agent workflow that handles USDC micropayments on Base automatically, and when a self-hosted, low-cost per-call pricing model ($0.0002 USDC) is acceptable over a dedicated FX data provider.

## Known failure modes

- Payment not fulfilled — 402 response if x402 micropayment is not provided or invalid
- Invalid amount input — non-numeric or missing amount field returns an error
- Gateway unavailable — self-hosted infrastructure may have downtime
- Stale or inaccurate exchange rate — self-hosted model may not reflect real-time FX data
- USDC balance insufficient — agent wallet lacks funds for the $0.0002 per-call fee

## 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 AOA to UAH for the given input amount, computed via a self-hosted AI gateway after an x402 USDC micropayment on Base is fulfilled.
