## 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 ars-to-cad-currency-converter-a01cdb00 -d '<json body>'
```

Example prompt: What is 2500 Argentine pesos worth in Canadian dollars right now?

## When to prefer this

Choose this endpoint when you need a quick, programmatic ARS-to-CAD conversion and are already operating within an x402 micropayment-enabled agent workflow. It is well-suited for lightweight, per-call currency lookups where cost-per-call pricing ($0.0002 USDC) is acceptable and you want a self-hosted, non-centralized alternative to large FX API providers.

## Known failure modes

- Invalid or non-numeric amount input returns an error
- Missing x402 micropayment header results in 402 Payment Required before executing
- Upstream exchange rate data unavailable causes conversion failure
- Negative or zero amount may be rejected
- Network timeout from self-hosted infrastructure

## 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 representing the equivalent of the input ARS amount in Canadian dollars, likely including the converted figure and possibly the exchange rate used.
