Example prompt: What's today's official daily reference exchange rate from USD to JPY? I need it for pricing normalization on an invoice.

## When to prefer this

Use this endpoint when you need an official, reliable daily reference exchange rate for pricing normalization, invoicing, or financial reporting — not for live trading or real-time tick data. Best for agents that need a trustworthy single daily FX rate across major ISO 4217 currency pairs at low cost per call.

## Known failure modes

- Unsupported or non-ISO 4217 currency code returns an error or empty rate
- Non-business days may return the most recent available rate rather than a fresh one
- Rate is cached up to 1 hour so may not reflect the exact moment of request
- Currency pairs outside the ~30 supported majors may not be available

## How this service works

Foreign exchange rate API: the official daily reference rate for any major fiat currency pair (~30 ISO 4217 currencies — USD, EUR, GBP, JPY, CHF, AUD...), as structured JSON with the rate date. Published once per business day — ideal for pricing normalization, invoicing, and financial reporting agents; not a live trading feed. Cached 1 hour.

## Output

A JSON object containing the exchange rate between the requested base and quote currencies (defaulting to USD/EUR), along with the date the rate was published, sourced from official daily reference data and cached up to 1 hour.
