## 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 amanchain-fiat-fx-rates-b59cd6f9 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need live, deterministic fiat FX rates paid per-call without an API key or account setup, especially in agent workflows that require micro-payment-based access via x402 on Base. Prefer it over traditional FX APIs when operating in a crypto-native, permissionless environment or when you need rates for 30+ currencies without subscription overhead.

## Known failure modes

- Unsupported currency code returns an error or empty result
- Malformed JSON body or missing serviceId field causes a 400-level error
- x402 payment failure or insufficient USDC balance prevents execution
- Temporary AmanChain node unavailability causes a 5xx error
- Rate data may lag slightly if consensus state is between blocks

## How this service works

Fiat Exchange Rates: live fiat FX rates and conversion across 30+ currencies Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-fx-rates","request":"<input>"}. No account, no API key.

## Output

A JSON response containing live fiat exchange rates for the requested currency pair(s) or conversion result, sourced from AmanChain's consensus state. Typically includes the rate, possibly the converted amount, and a timestamp or block reference.
