## 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-all-currency-rates-converter-1dcd347d -d '<json body>'
```

Example prompt: What's 5000 Argentine pesos worth in every major currency right now? Give me the full conversion table.

## When to prefer this

Choose this endpoint when you need a comprehensive ARS-to-all-currencies rate table in a single call, rather than querying individual currency pairs one at a time. Ideal for bulk conversions, portfolio reporting, or multi-market pricing where the Argentine peso is the base currency.

## Known failure modes

- Invalid amount type returns validation error
- Upstream forex data unavailable causes 500 or stale-rate response
- Missing x402 micropayment header returns 402 Payment Required
- Rate limiting if micropayment not processed correctly

## How this service works

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