Exchange Rate
Real-time currency exchange rate and conversion using QVeris tools.
What This Skill Does
Exchange Rate provides:
- Rate lookup – Current exchange rate between two currencies (e.g. USD/EUR, CNY/JPY).
- 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_KEYonly. - Read-only, no side effects; suitable for travel, trade, and reporting.
Core Workflow
- Parse user intent: rate (from_currency, to_currency) or convert (from_currency, to_currency, amount).
- Search QVeris for tools: e.g. "currency exchange rate real-time", "currency conversion".
- Rank results by success_rate, latency, and parameter fit (rate vs conversion).
- Build request parameters: for rate use
from_currency/to_currencyorsymbol(e.g.EUR/USD); for conversion addamount. - Execute chosen tool with 5s timeout; on failure try next candidate.
- 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
