How crypto pricing works.

A one-minute primer. Already know your way around? Skip ahead to our exchange network.

  • Exchanges, not dealing rooms

    Unlike FX, crypto trades on public exchanges with open order books — anyone can see the prices being made. Our job is to read those markets accurately and turn them into one dependable rate.

  • Prices differ by venue

    The same coin trades at slightly different prices on different exchanges at the same moment. No single venue is 'the' price — which is why we aggregate across the market's largest exchanges rather than relying on any one of them.

  • Crypto never closes

    There's no opening bell and no weekend gap — crypto trades around the clock, every day of the year. Our feed runs continuously to match, refreshing prices as often as every second.

  • From coins to any currency

    Crypto is mostly priced against the US dollar. We combine those prices with our institutional FX feed, so you can quote 500+ digital assets in any of our 170+ supported currencies with one API call.

Priced across the world's largest exchanges.

What aggregation means for your crypto data.

  • Representative

    No single exchange sets the price. Aggregating across major venues smooths out per-exchange quirks and gives you a rate that reflects the whole market.

  • Resilient

    Exchanges have outages, maintenance windows and localised anomalies. A multi-venue feed keeps your pricing steady when any single source wobbles.

  • Fiat-ready

    Crypto prices combine with our institutional FX feed, so any coin can be quoted in any of 170+ currencies — one API, both worlds.

  • Transparent

    We tell you how our pricing is built and where it comes from — the same standard we hold every data point on this site to.

Crypto data sources — FAQ.

Where the numbers come from, and what you can build on them.

Where do fastFOREX API crypto prices come from?
We aggregate pricing from the world's largest digital-asset exchanges — including Coinbase, Binance, Kraken, Bybit, KuCoin, Gate and Crypto.com — rather than relying on any single venue.
Why is your rate different from what I see on my exchange app?
Exchange apps show one venue's order book at one moment. Our rate is an aggregate across venues, so it can sit slightly above or below any individual exchange — that's the point: it represents the market, not a single book.
Are these executable trading quotes?
No. fastFOREX API provides market data — indicative pricing for applications, analytics and reporting. We are not an exchange or a trading venue, and our rates are not offers to deal.
How fresh is the pricing?
Crypto prices refresh as often as every second, depending on your plan — and because crypto never closes, the feed runs 24/7, weekends and holidays included.
Can I get crypto priced in currencies other than USD?
Yes. Our crypto pricing combines with our FX feed, so /fetch-one, /fetch-multi and /convert can quote any supported coin in any of our 170+ physical currencies.
