Implementation notes

When to use coinlayer

coinlayer serves crypto exchange rates in the exact same request/response shape as Fixer and Currencylayer — which is its real selling point: if your codebase already consumes one APILayer currency product, adding crypto is a base-URL change. 385+ coins aggregated from 25 exchanges, live and historical. For crypto-only projects, CoinGecko's free tier is richer; coinlayer wins when API-shape consistency across fiat + crypto matters.

Common pitfalls

Rates are averaged across exchanges — fine for display and conversion features, wrong for anything trading-adjacent where the venue-specific price matters.
The free tier updates rates every 60 minutes, not in real time. The `timestamp` field tells you the actual data age; surface it in your UI.
Free tier is HTTP only, like the other APILayer products.
