Bank of Lithuania Exchange Rates API — bank-of-lithuania-exchange-rate

Official Bank of Lithuania (Lithuania) daily exchange rates for Node.js and TypeScript. The published central bank rates behind tax filings, customs valuations, audits, and compliant invoicing — not market estimates, but the numbers Bank of Lithuania itself prints, every business day.

🚀 Why this client?

• 🏛️ Official rates — Bank of Lithuania's own table, with the publisher's own rate_date on every response
• 📅 History back to 2015 — point-in-time tables and daily series for any past date
• 🔀 Official vs derived, always flagged — computed inverse/cross pairs carry derived: true, never mixed with official prints
• ⚡ Zero dependencies — pure ESM + CJS over global fetch; Node 18+, Bun, Deno, and edge runtimes
• 🔷 Type-safe — full TypeScript definitions shipped with the package
• 🧾 Compliance-grade metadata — rate_type, publication date, and source disclaimer on every response

Official rate, not mid-market: every value here is a number Bank of Lithuania itself published, fixed once printed and carrying the central bank's own rate_date — what filings and audits require. Need the live mid-market rate for pricing or display instead? Use the mid-market API or @allratestoday/sdk. The two can diverge by several percent.

📈 Latest official table

The image is rendered live from the keyless endpoint, so it follows the central bank's publications on npm and on GitHub alike without a new release. The same table as text is folded below for search and copy-paste: on GitHub a daily Action refreshes it whenever the central bank publishes a new table; on npm it is as of the package's publish date.
