ve-exchange-rates

运行 Python（Bash 薄封装）脚本抓取 bcv.org.ve 官方汇率与 Binance P2P USDT 均价，计算 brecha 汇率差并给出 100 美元换算与损失；BCV 不可用时回退 exchangerate-api.com，均失败则只报错不编造数值。

Get Venezuelan exchange rates - BCV official rate, Binance P2P USDT average, and the gap between them. Use when user asks for Venezuelan dollar rates, brecha cambiaria, dolar BCV, USDT P2P, or exchange rates in Venezuela.

ve-exchange-rates: Venezuelan Exchange Rates

Get current exchange rates for Venezuela:

  1. Tasa BCV - Official Central Bank rate from the BCV website
  2. Tasa USDT Binance P2P - Average from P2P market
  3. Brecha cambiaria - Gap between official and parallel rates

Usage

Run the wrapper script to get current rates:

./skills/ve-exchange-rates/scripts/get-rates.sh

The shell script is now a thin wrapper around a Python implementation:

python3 ./skills/ve-exchange-rates/scripts/get_rates.py

Output

The script returns:

  • BCV official rate (Bs/USD)
  • BCV source used
  • BCV "Fecha Valor" extracted from the site
  • Warning if the BCV date does not match the expected current run window
  • Binance P2P USDT rates (buy/sell/average)
  • Gap percentage between BCV and P2P
  • Example conversion from 100 USD at BCV rate into USDT at P2P rate
  • USDT lost because of the exchange-rate gap

Response format guidance

When using this skill for a user-facing reply, prefer returning the complete summary instead of only one metric.

Default response should include:

  • BCV
  • USDT Binance P2P
  • Brecha
  • 100 USD BCV = X USDT
  • Pérdida por brecha

If available, also include:

  • Fuente BCV
  • Fecha Valor BCV
  • warning when the BCV date does not match the current expected run window

Only shorten the response if the user explicitly asks for a single field.

Data Sources

  • BCV rate: scraped directly from bcv.org.ve
  • BCV validation: extracts and validates Fecha Valor from the BCV page
  • Fallback for BCV: exchangerate-api.com only if BCV cannot be parsed
  • USDT P2P: Binance P2P API (p2p.binance.com)

If neither BCV nor the fallback source returns a rate, or if the Binance P2P price cannot be fetched, the skill reports the failure and exits without computing any rates. It never invents, estimates, or hardcodes a value.

Notes

  • BCV is the primary source and should be treated as the authoritative rate
  • The skill warns when the BCV "Fecha Valor" does not match today or tomorrow
  • P2P rates fluctuate constantly based on market conditions
  • Main implementation now lives in Python for readability and easier auditing
  • The shell entrypoint is only a thin wrapper that invokes get_rates.py
  • The implementation uses only the Python standard library (urllib for HTTP, decimal for math) — no external commands or dependencies
  • If BCV is temporarily unavailable, the skill tries a secondary source; if that also fails it reports the error and does not report a rate
