## 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-myr-currency-converter-d48d07bd -d '<json body>'
```

Example prompt: Convert 250 ANG to MYR — what's the current exchange rate and how much would I get?

## When to prefer this

Choose this endpoint when you need ANG (Netherlands Antillean Guilder) to MYR (Malaysian Ringgit) currency conversion and are operating in an x402-enabled payment environment using USDC on Base. Ideal for agents already integrated with the x402 micropayment protocol that need niche currency pair conversions not always available in mainstream FX APIs.

## Known failure modes

- Payment not received or insufficient USDC micropayment — 402 Payment Required returned
- Invalid or missing amount parameter — may default to 1 or return validation error
- Upstream FX rate data unavailable — service may return an error or stale rate
- Network timeout on self-hosted infrastructure — intermittent availability possible

## How this service works

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

## Output

Returns the converted currency value and FX rate data for the ANG to MYR currency pair, given the input amount. Response is a JSON object with conversion results.
