Exchange Rate

Real-time currency exchange rate and conversion using QVeris tools.

What This Skill Does

Exchange Rate provides:

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.

Supported via QVeris: forex and common fiat pairs; optional historical date for rate/conversion when the tool supports it.

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).

Command Surface

Primary script: scripts/exchange_rate.mjs

• Get rate only:
  • node scripts/exchange_rate.mjs rate --from USD --to EUR
  • node scripts/exchange_rate.mjs rate --from CNY --to USD
• Convert amount:
  • node scripts/exchange_rate.mjs convert --from USD --to JPY --amount 1000
  • node scripts/exchange_rate.mjs convert --from EUR --to GBP --amount 500

Optional: --date YYYY-MM-DD for historical rate/conversion when the tool supports it; --format json for machine-readable output.

Safety and Disclosure

• Uses only QVERIS_API_KEY; no other secrets.
• Calls only QVeris over HTTPS; no package install or arbitrary commands.
