Reserve Bank of India Exchange Rates API — rbi-exchange-rate

Official Reserve Bank of India (India) 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 Reserve Bank of India itself prints, every business day.

🚀 Why this client?

• 🏛️ Official rates — Reserve Bank of India's own table, with the publisher's own rate_date on every response
• 📅 History back to 2003 — 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 Reserve Bank of India 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.

Base	Quote	Type	Rate
AED	INR	reference	25.5288
EUR	INR	reference	103.8419
GBP	INR	reference	124.2808
IDR	INR	reference	0.00513656
JPY	INR	reference	0.5866
