## 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 sixpath-exchange-rate-api-cf84401a -d '<json body>'
```

Example prompt: What's the current exchange rate from USD to EUR, and how much would 250 US dollars be in euros right now?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call forex lookup without a subscription to a dedicated FX data provider. It is well-suited for agents that only occasionally need exchange rates and want to pay micro-amounts via x402 on Base chain rather than maintain an API key with a traditional FX service.

## Known failure modes

- Unsupported or invalid currency code returns an error response
- Network or upstream ExchangeRate-API outage causes failure
- Payment not processed on Base chain results in 402 rejection
- Rate data may be delayed or stale if upstream provider has not refreshed
- Missing required parameters (base or target currency) result in a 400-style error
