Every global fintech app has the same heartbeat: exchange rates. Whether it's a money transfer landing across the world, a crypto trade firing at midnight, or a dashboard tracking market moves, your users expect one thing — numbers they can trust.
That’s where FinFeedAPI’s Currencies API comes in.
It gives you live FX rates, deep historical data, crypto pricing, and precise time-stamped snapshots — all through one simple interface.
Real-time rates come from:https://api-realtime.fx.finfeedapi.com
Historical data comes from:https://api-historical.fx.finfeedapi.com
One API key in the header — and you’re in.
Real-Time FX Data: When Speed Actually Matters
Some apps can wait. Money transfers and trading apps can’t.
Real-time rates from FinFeedAPI give you VWAP-24H pricing, aggregated across reliable sources, so your users don’t get blindsided by stale or noisy numbers.
Live FX endpoint
/v1/exchangerate/{asset_id_base}/{asset_id_quote}
Returns the current rate — fiat, crypto, or a mix of both.
Perfect for:
- instant conversions
- checkout pricing
- trading triggers
- market alerts
Every response includes a precise timestamp, which means your UI can always show exactly when the quote was generated.
Live rates for all pairs
/v1/exchangerate/{asset_id_base}
Get every conversion from one base asset in a single call.
Supports:
- quote filtering
- inverted rates (useful for crypto pairs)
This is how you build converters, watchlists, and pricing engines that feel alive, not delayed.
Historical FX Data: The Engine Behind Charts, Reports, and Forecasting
Real-time FX drives action.
Historical FX explains it.
FinFeedAPI’s historical data spans years of pricing, down to granular time periods. That lets you build tools that reveal trends — not just snapshots.
Point-in-time lookup
/v1/exchangerate/{base}/{quote}?time={timestamp}
You get the exact price at the exact second.
This is huge for:
- financial reports
- invoice reconciliation
- auditing past transactions
- backtesting strategies
Full historical timeseries
/v1/exchangerate/{base}/{quote}/history
Returns OHLC (open, high, low, close) for every period — minute, hour, or day.
You control:
period_id(1MIN, 1HRS, 1DAY, etc.)- time ranges
- up to 100,000 data points per request
This is the foundation of:
- charting tools
- analytics dashboards
- volatility models
- economic research
Supported periods
/v1/exchangerate/history/periods
Tells you exactly which intervals you can request.
