How has INR trended against USD in 2026, and what were the key highs and lows?

INR has depreciated against USD through 2026, with USD/INR reaching a high near 86 mid-year before moderating. The rupee faced headwinds from a strong dollar and capital outflows, with the RBI intervening at key support levels to smooth volatility.

How did EUR perform against USD over the last decade?

FAQ

Common questions

Is the MCP server included on every plan?

Yes. The MCP server is included on every CurrencyCore plan, including the free tier. Each tool call counts as one API request toward your monthly quota. No extra setup, no additional cost.

How do AI credits work?

1 AI credit = 1 query to the /v1/ai natural-language endpoint. The free tier includes 100 AI credits per month. AI credits and API requests are separate pools. You can top up AI credits any time via the dashboard without changing your plan.

How far back does historical data go, and do I need a paid plan?

Historical rates go back to 1949 across 160+ currencies, sourced from the European Central Bank. The free tier includes the last 30 days of history. Starter plan and above unlock the full 75+ year dataset. The /history/analysis endpoint (trend analysis, movers) requires Growth plan.

Where does the rate data come from?

Rates are sourced from the European Central Bank (ECB) daily reference dataset and refreshed hourly. Historical rates use carry-forward resolution for non-trading days, so every date returns a valid, reproducible value. PPP factors come from the IMF World Economic Outlook, updated annually.

Can I bring my own AI model?

Yes. Growth Plus plans support Bring Your Own Key (BYOK): connect your own OpenAI, Anthropic, Azure, or any OpenAI-compatible model. BYOK queries are billed as API requests, not AI credits, so they do not consume your credit balance.

Understand currencies. Not just exchange rates.

Free forever. 1,000 API requests + 100 AI credits/month. No credit card required.
