## 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 mcpfax-fx-markets-data-50080054
```

Example prompt: What's the current EUR/USD exchange rate? I need live FX market data from MCPFax markets.

## When to prefer this

Use this endpoint when you need real-time or near-real-time FX/forex market rates and are operating within an x402 micropayment-capable agent environment. It is part of a broader MCPFax markets suite (also covering crypto, gas, macro, rates, stablecoin), so prefer this specifically for fiat currency pair exchange rates rather than crypto or macro data.

## Known failure modes

- Invalid or unsupported currency pair returns an error
- Payment not fulfilled results in 402 Payment Required
- Malformed request body returns 400 Bad Request
- Service unavailability returns 5xx error
- Rate limit exceeded if too many requests are made

## How this service works

FX reference rates — ECB reference foreign-exchange cross rates.

## Output

Returns current foreign exchange rate data for the requested currency pair(s), likely including bid/ask prices, mid-market rate, and timestamp of the quote.
