Exchange Rate

What This Skill Does

1. Rate lookup – Current exchange rate between two currencies (e.g. USD/EUR, CNY/JPY).
2. Amount conversion – Convert an amount from one currency to another at current rates.

Key Advantages

• Uses only QVeris API: search for tools by capability, then execute; no hardcoded provider list.
• Fallback across providers (e.g. Alpha Vantage, Twelve Data) when one fails or is unavailable.
• Same credential as other skills:

  QVERIS_API_KEY

  only.
• Read-only, no side effects; suitable for travel, trade, and reporting.

Core Workflow

1. Parse user intent: rate (from_currency, to_currency) or convert (from_currency, to_currency, amount).
2. Search QVeris for tools: e.g. "currency exchange rate real-time", "currency conversion".
3. Rank results by success_rate, latency, and parameter fit (rate vs conversion).
4. Build request parameters: for rate use

   from_currency

   /

   to_currency

   or

   symbol

   (e.g.

   EUR/USD

   ); for conversion add

   amount

   .
5. Execute chosen tool with 5s timeout; on failure try next candidate.
6. Return formatted rate and/or converted amount (markdown or JSON).
