## How to call it through Zero

```

Example prompt: Can you pull up today's full currency exchange rate table using EUR as the base currency — I want to see what all the major currencies are worth relative to the Euro right now?

## When to prefer this

Use this endpoint when you need a full FX rate table for a given base currency using official ECB daily reference rates, without needing an API key or subscription. Ideal for agents that need a broad snapshot of currency rates rather than a single pair conversion, and that can handle pay-per-call micropayment billing via x402 or MPP.

## Known failure modes

- Invalid or unsupported ISO-4217 currency code returns an error
- Payment not completed via x402/MPP results in 402 Payment Required response
- ECB rates not yet published for the day may return stale or unavailable data
- Missing base parameter defaults to USD rather than failing

## How this service works

Pay-per-call currency and unit conversion utility for AI agents: currency exchange at ECB daily reference rates, FX rate tables, and physical unit conversion (length, mass, temperature, volume, area, speed, time, digital). No API key, no subscription — agents pay per request via x402 (Base/USDC) or MPP (Tempo/pathUSD).

## Output

A table of exchange rates for all supported currencies relative to the specified base currency (defaulting to USD), sourced from ECB daily reference rates. Includes rate values for each currency pair.
