Pricing overview

ExchangeRate-API utilizes a subscription-based pricing model primarily determined by the volume of API requests. This structure is designed to accommodate various user needs, from individual developers utilizing the free tier for basic testing and small-scale projects to large enterprises requiring extensive historical data and high request limits. The core offering across all tiers is access to current and historical foreign exchange rates, with higher tiers unlocking advanced features such as more frequent updates, dedicated support, and increased request allowances.

The service provides a free tier, which allows users to make a limited number of requests per month without charge. Beyond this free allowance, users can subscribe to various paid plans, each offering a specific number of requests and features for a monthly fee. This approach is common among API providers, where resource consumption is directly tied to usage. For instance, similar models are employed by services like Stripe for payment processing APIs and Google Maps Platform for location-based services, where costs scale with API call volume.

Users considering ExchangeRate-API pricing should evaluate their anticipated request volume, the necessity of historical data, and the required update frequency for exchange rates. The official ExchangeRate-API pricing page provides detailed breakdowns of each plan's inclusions and limitations, enabling developers and technical buyers to select an appropriate tier for their applications.

Plans and tiers

ExchangeRate-API's pricing structure is divided into several tiers, each designed to meet different levels of demand for currency exchange rate data. These tiers vary primarily in the number of API requests allowed per month, the frequency of exchange rate updates, and access to historical data. The plans begin with a free tier and scale up to enterprise-level solutions.

The following table summarizes the key aspects of ExchangeRate-API's typical plans. Specific pricing and features can be found on the official pricing page.

Plan Name Monthly Price Key Limits / Features Best For
Free $0 1,500 requests/month, 15-minute updates, limited historical data Basic testing, personal projects, very low-volume applications
Starter $10 20,000 requests/month, 10-minute updates, full historical data Small businesses, startups, applications with moderate traffic
Professional $25 100,000 requests/month, 5-minute updates, full historical data, priority support Growing e-commerce sites, financial dashboards, travel platforms
Business $50 500,000 requests/month, 1-minute updates, full historical data, advanced support Large-scale applications, high-traffic financial services, enterprise solutions
Enterprise Custom Custom requests/month, real-time updates, dedicated infrastructure, SLA Very large organizations, high-frequency trading, mission-critical systems

The ExchangeRate-API documentation details the specific API endpoints available at each tier, including access to standard currency conversion, historical rates, and currency list endpoints. Users should review these details to ensure the chosen plan aligns with their technical requirements.

Free tier and limits

ExchangeRate-API provides a free tier designed for initial testing, development, and low-volume personal projects. This tier allows users to make up to 1,500 requests per month without incurring any costs. The free tier includes access to the core currency exchange rate functionality, enabling developers to integrate and test the API's capabilities before committing to a paid plan.

Key limitations of the free tier include:

  • Request Volume: Limited to 1,500 requests per month. Exceeding this limit typically results in rate limiting or a requirement to upgrade to a paid plan.
  • Update Frequency: Exchange rates are generally updated every 15 minutes. This frequency may be sufficient for many applications but could be a limitation for those requiring near real-time data.
  • Historical Data: Access to historical exchange rate data may be limited in scope or depth compared to paid tiers.
  • Support: Support options are typically community-based or limited to basic inquiries, without dedicated or priority support channels.

The free tier is suitable for:

  • Developers prototyping new applications.
  • Personal websites or blogs displaying basic currency conversions.
  • Educational projects or learning environments.
  • Applications with very infrequent needs for exchange rate data.

For applications with higher traffic, more frequent data updates, or extensive historical data requirements, upgrading to one of the paid plans is necessary. The free tier serves as an entry point, allowing users to evaluate the API's performance and ease of integration, as noted in the developer experience notes.

Real-world cost examples

Understanding the practical implications of ExchangeRate-API's pricing model can assist in budgeting and resource allocation. The cost primarily depends on the number of API requests your application makes per month.

Consider the following scenarios:

  1. Small E-commerce Store: An online store that displays prices in two additional currencies on product pages. If each product page view triggers an API call (e.g., to convert the base price), and the store receives 500 unique product page views per day, this would equate to approximately 15,000 requests per month (500 views/day * 30 days/month). In this scenario, the Starter plan at $10/month, offering 20,000 requests, would be appropriate. This provides a buffer for occasional spikes in traffic or additional API calls for other features like a currency converter widget.

  2. Travel Booking Platform: A travel platform that needs to convert flight and hotel prices for users in various regions. If the platform serves 3,000 active users daily, and each user session averages 5 API calls for currency conversion (e.g., searching flights, viewing hotel details, booking confirmation), this would be 15,000 requests daily, totaling 450,000 requests per month (15,000 requests/day * 30 days/month). For this usage, the Business plan at $50/month, which includes 500,000 requests, would be a suitable choice. This plan also offers more frequent updates (1-minute), which is beneficial for volatile travel pricing.

  3. Financial Dashboard for Personal Use: A developer builds a personal financial tracker that fetches current exchange rates once an hour for 10 different currency pairs. This would result in 240 requests per day (10 pairs * 24 hours), or approximately 7,200 requests per month (240 requests/day * 30 days/month). The Starter plan at $10/month would comfortably cover this usage, and even the free tier could potentially suffice if the update frequency was reduced or fewer currency pairs were tracked.

  4. Enterprise Trading Application: A large financial institution requires real-time exchange rates for high-frequency trading across hundreds of currency pairs, making thousands of requests per minute. This level of demand would necessitate the Enterprise plan. The cost would be custom-quoted based on specific requirements, including dedicated infrastructure, service level agreements (SLAs), and potentially direct data feeds for sub-second updates. This custom approach ensures the API can meet the stringent demands of mission-critical financial systems, as outlined in the enterprise solution details.

These examples illustrate how different usage patterns translate into specific plan recommendations and costs, emphasizing the importance of accurately estimating API request volume.

How the pricing compares

When evaluating ExchangeRate-API's pricing, it is useful to compare it with alternative currency exchange rate API providers. The market for exchange rate APIs includes several competitors, each with varying pricing models, feature sets, and update frequencies. Common alternatives include Open Exchange Rates, Fixer, and Currencyapi.com.

  • Open Exchange Rates: Open Exchange Rates also offers a free tier, typically providing 1,000 requests per month with hourly updates. Their paid plans start at around $12 per month for 10,000 requests, offering more frequent updates and access to historical data. Compared to ExchangeRate-API's 1,500 free requests and 20,000 paid requests for $10, Open Exchange Rates might be slightly more expensive for similar request volumes, though feature sets can vary. Developers can review the Open Exchange Rates pricing page for current details.

  • Fixer: Fixer provides a free plan with 1,000 requests per month and hourly updates. Their paid plans typically start at €14 (approximately $15-16 USD) per month for 10,000 requests, including historical data and more frequent updates. Fixer's pricing can be slightly higher than ExchangeRate-API for comparable tiers, especially when considering the Euro-to-Dollar conversion. The Fixer pricing overview offers specific plan details.

  • Currencyapi.com: Currencyapi.com offers a free plan with 300 requests per month and hourly updates. Their paid plans generally start around $9.99 per month for 10,000 requests. While slightly cheaper for the initial paid tier, their free tier offers fewer requests than ExchangeRate-API. The Currencyapi.com pricing plans provide a comprehensive breakdown of their offerings.

In summary, ExchangeRate-API generally offers a competitive free tier with 1,500 requests, which is more generous than some alternatives. Its starting paid tier at $10 for 20,000 requests also presents a strong value proposition compared to competitors offering fewer requests for a similar or higher price point. The choice between these providers often comes down to specific feature requirements, such as update frequency, currency coverage, historical data depth, and the exact volume of API calls anticipated. Users should also consider the quality of documentation and support, which can impact the overall developer experience, as highlighted in ExchangeRate-API's documentation.
