## 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-ang-to-mxn-converter-29478ea5 -d '<json body>'
```

Example prompt: What is 250 ANG worth in Mexican pesos right now? Use the FX converter to get me the current rate.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call ANG to MXN currency conversion without API key subscriptions, particularly in an x402-compatible agent environment that can handle USDC micropayments on Base. Suitable for infrequent, on-demand conversions where a subscription FX API is overkill.

## Known failure modes

- Payment not included or insufficient USDC micropayment — returns HTTP 402 requiring x402 payment
- Invalid or missing amount field — returns validation error
- Amount is zero or negative — may return error or zero result
- Exchange rate data unavailable — may return error or stale rate
- Network/gateway timeout — returns 5xx error

## How this service works

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

## Output

A JSON object containing the converted currency value in MXN for the given ANG amount, likely including the exchange rate applied and the resulting peso figure.
