E-commerce & Marketplace Platforms
Display Accurate Prices Globally with Real-Time Currency Conversion
Start Now
Most e-commerce platforms struggle with static pricing that creates poor user experiences and lost sales opportunities.
Without real-time currency conversion and dynamic pricing capabilities, online retailers face high cart abandonment rates, customer confusion over pricing, and missed revenue from international markets. When your platform can't provide accurate local pricing, transparent conversion rates, or consistent checkout experiences, global expansion and customer retention become impossible.
What are the pain points when building global e-commerce platforms?
Currency mismatch at checkout causes customers to abandon carts when prices are only shown in a foreign currency, reducing conversion rates and international sales.
Pricing discrepancies during volatile markets occur when FX or crypto rates change quickly, leading to mismatched displayed vs. charged prices, disputes, and refunds.
Manual currency updates create operational overhead as teams spend hours adjusting catalog prices for each market.
Multi-currency profitability blind spots make it hard to see true margins across regions when costs and revenues are in different currencies.
Inability to run accurate pricing experiments results in unreliable A/B test outcomes without a consistent and accurate conversion baseline.
Refund and return reconciliation challenges arise when historical rates aren’t available to match the original payment currency, creating disputes and customer dissatisfaction.
Slow market entry due to lack of localized pricing delays expansion into new regions and limits competitiveness.
How does CoinAPI solve these issues?
Deliver Accurate, Real-Time Currency Data to Power Global E-commerce
- Battle-tested interfaces: REST for broad access, WebSocket for live streaming, and FIX for finance-grade sessions - pick the right pipe for cart, catalog, or pricing engines.
- Global routing for speed & reliability: Default endpoints use GeoDNS to route requests to the nearest region, with explicit NCSA / EMEA / APAC endpoints if you want to pin traffic regionally.
- Operational transparency: Every authenticated REST response can return rate-limit and concurrency headers so your team can monitor quota, remaining capacity, and reset timing in code and dashboards.
- Lean bandwidth under peak: Support for response compression (br/gzip); enabling compression typically reduces bandwidth by ~80%, which helps during promos and flash sales.
- Developer velocity: Official SDKs/examples on GitHub (Python, Java, .NET, JS/TS, Go, etc.) to cut integration time and reduce edge-case bugs.
Enable dynamic, real-time pricing for global customer experiences
- Instant currency conversion so customers see accurate local prices at every step, reducing cart abandonment and confusion.
- Pricing stability during market volatility with rates updated every second, minimizing mismatched displayed vs. charged prices.
- Automated catalog updates through API-driven bulk currency conversion, eliminating manual price changes across SKUs.
- Multi-currency cart management powered by CoinAPI data to allow price comparison and currency preference selection.
Maintain Pricing Accuracy Even in Volatile Markets
- VWAP24 as the base: Exchange rates are defined as a rolling 24-hour Volume-Weighted Average Price across multiple sourcesMarket data API docs.
- Quality sources only: Non-spot symbols are excluded and only the highest-legitimacy exchanges for each pair are used; questionable sources are droppedMarket data API docs.
- Data hygiene under volatility:
- Discards quotes with abnormal spreads (> 67%)Market data API docs
- Uses mid-quote weighted by passive volume on best pricesMarket data API docs
- Weights by trade volume in the VWAP24 algorithmMarket data API docs
- Drops stale midpoints not updated within 5 minutes 1 secondMarket data API docs
- Outlier filtering (3-sigma) when ≥3 exchanges report the pairMarket data API docs
- Freshness: VWAP24 data is updated every 1 second across asset pairsMarket data API docs.
Reduce cart abandonment with transparent, local pricing
- Instant local currency display eliminates guesswork for international customers.
- Accurate, consistent rates keep pricing aligned across product pages, cart, and checkout.
- Transparent exchange rate display builds trust and reduces refund disputes.

Enterprise infrastructure built for global e-commerce scale
- Global routing: Default REST endpoints auto-route via GeoDNS; pin to api-ncsa, api-emea, or api-apac for region-specific traffic controlMarket data API docs.
- Capacity controls: Rate-limit and concurrency headers let you program defensively (throttle, backoff, alerting) without guessworkMarket data API docs.
- Bandwidth efficiency: Enable br/gzip to cut payloads by ~80%, ideal for bulk price refresh and high-SKU catalogsMarket data API docs.
- Standards-friendly: ISO 8601 time formats, consistent precision rules, and standardized symbology for fiat (ISO 4217) and crypto tickersMarket data API docs.
