## 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 01mind-fx-rates-api-a8f73531 -d '<json body>'
```

Example prompt: What's the current exchange rate from USD to EUR? Pull the live ECB rate right now.

## When to prefer this

Choose this endpoint when you need live, ECB-sourced foreign exchange reference rates at very low cost ($0.002/call) and high trust (verified against actual API contract). Ideal for agents that need grounded, non-fabricated FX data without hallucination risk. Prefer over alternatives when ECB reference rates are acceptable (vs interbank or commercial rates) and when you want a simple, reliable lookup with a clear audit trail.

## Known failure modes

- Unsupported or invalid currency code returns an error — only currencies covered by ECB reference rates are available
- Frankfurter.dev upstream outage may cause failures or stale data
- Malformed request body or missing required fields returns a 4xx error
- ECB rates are updated on business days only — weekend/holiday queries return the most recent available rate, not a real-time price

## How this service works

Real-time foreign exchange rates — $0.002/call, trustScore 90. Real wrapper around frankfurter.dev (ECB reference rates), no fabricated data. Query any base currency, get one rate or the full set — real, live, verified against the actual current API contract.

## Output

A JSON object containing one or more real-time foreign exchange rates sourced from the ECB via frankfurter.dev, keyed by currency code, for the specified base currency. Can return a single rate for a target currency or the full set of rates for the base currency.
