Fixer Pricing: Real-time Currency Exchange API Costs (2026)

Pricing overview

Fixer offers an API for real-time and historical currency exchange rates, operating on a tiered subscription model primarily based on the volume of API requests. The service includes a free tier, providing a limited number of requests per month, suitable for evaluation or low-volume applications. Paid plans scale upwards in terms of monthly request allowances, typically offering additional features such as HTTPS encryption, historical data access, and a broader range of available currency sources as plan tiers increase. Enterprise-level solutions are available for organizations requiring custom request volumes, dedicated support, or specific integration requirements Fixer pricing details.

The pricing structure is designed to accommodate various user segments, from individual developers and small businesses to large enterprises needing extensive financial data feeds. Each plan specifies a maximum number of API requests, indicating the volume of data calls that can be made within a billing cycle. Exceeding these limits typically incurs additional charges or requires an upgrade to a higher tier. The service emphasizes data accuracy and timely updates, which are core components of its value proposition for financial applications and e-commerce platforms Fixer API documentation overview.

Plans and tiers

Fixer provides several subscription plans, each designed to meet different usage patterns and feature requirements. The primary differentiators across these plans are the monthly API request limit, access to specific data types (e.g., historical data, time-series data), and security features like HTTPS encryption.

The plans available generally include:

• Free Plan: A foundational tier for initial testing and minimal usage.
• Basic Plan: An entry-level paid option for small applications.
• Professional Plan: Geared towards businesses with moderate data needs.
• Business Plan: For larger applications and increased data demands.
• Enterprise Plan: Custom solutions for high-volume or specialized requirements.

The following table outlines the key aspects of Fixer's standard plans:

Prices are subject to change and may vary based on billing frequency (monthly vs. annual). Annual subscriptions often include a discount compared to monthly payments Fixer subscription options.

Free tier and limits

Fixer provides a free tier designed to allow users to evaluate the API's functionality and integrate it into low-usage applications without cost. This free plan includes a limit of 250 API requests per month. Users on the free tier can access real-time exchange rates for a limited set of currency sources. While suitable for basic testing and development, it typically lacks advanced features like HTTPS encryption, historical data access, or the full range of currency symbols available in paid plans.

The free tier acts as an entry point, allowing developers to build and test applications that require currency data. For example, a developer building a personal finance tracker or a hobby e-commerce site might find the free tier sufficient for initial development. However, once an application scales or requires more robust features and higher request volumes, an upgrade to a paid plan becomes necessary. The transition from the free tier to a paid plan unlocks additional capabilities and increased request allowances, ensuring that applications can handle higher traffic and more complex data requirements Fixer free plan details.

Real-world cost examples

Understanding the practical costs of using Fixer requires considering typical application scenarios and how they align with the service's tiered pricing model.

Scenario 1: Small E-commerce Store

A small online store that displays product prices in multiple currencies might update exchange rates once an hour. If the store fetches rates for 5 different currencies, this translates to 5 API calls per hour. Over a 30-day month, this would be 5 calls/hour * 24 hours/day * 30 days/month = 3,600 API requests. This usage level would fit comfortably within the Basic Plan, costing approximately $14.99 per month for 10,000 requests. This plan also provides HTTPS encryption, crucial for production environments Fixer Basic plan features.

Scenario 2: Financial Portfolio Tracker

A web application that tracks multiple cryptocurrency and fiat currency portfolios for 500 users, updating rates every 15 minutes for 10 different currency pairs. Each update involves 10 API calls. Per hour, this is 40 calls (10 calls * 4 updates/hour). Over a month, this is 40 calls/hour * 24 hours/day * 30 days/month = 28,800 API requests. This usage falls within the Professional Plan, priced around $49.99 per month for 100,000 requests. This tier also grants access to historical data, which is often essential for portfolio analysis Fixer historical rates documentation.

Scenario 3: Global Payment Gateway Integration

A payment gateway processing thousands of international transactions daily requires real-time conversion rates for a high volume of requests. If the gateway performs an average of 15,000 currency conversions per day, each requiring an API call, this amounts to 15,000 calls/day * 30 days/month = 450,000 API requests. This usage would require the Business Plan, costing approximately $99.99 per month for 500,000 requests. This plan provides the necessary volume and features like time-series data and a dedicated conversion endpoint Fixer currency conversion endpoint.

Scenario 4: Mobile Banking Application

A mobile banking application used by millions of users might need to fetch exchange rates for multiple currencies multiple times per hour, or upon user request. Such an application could easily exceed 500,000 requests per month. For example, if 1 million users make an average of 0.5 requests per day, that's 500,000 requests/day, or 15 million requests/month. This volume would necessitate an Enterprise Plan, requiring a custom quote from Fixer. Enterprise plans typically include dedicated infrastructure, higher rate limits, and service level agreements (SLAs) tailored to specific organizational needs, ensuring reliability and performance for high-demand applications Fixer enterprise solutions.

These examples illustrate how usage patterns directly influence the appropriate Fixer plan and associated costs. Developers and businesses should accurately estimate their expected API request volume and feature requirements to select the most cost-effective plan.

How the pricing compares

When evaluating Fixer's pricing, it is useful to compare it against alternative currency exchange rate APIs available in the market. Competitors often offer similar tiered pricing models based on request volume and feature sets, but specific price points and included features can vary.

One notable alternative is ExchangeRate-API. ExchangeRate-API also offers a free plan with 1,500 requests/month, which is significantly higher than Fixer's 250 requests. Their paid plans start at around $10/month for 10,000 requests, which is slightly less than Fixer's Basic plan at $14.99 for the same volume. However, the specific features included at each tier, such as historical data access, available currency sources, and update frequency, require direct comparison.

Open Exchange Rates is another provider, offering a free tier with 1,000 requests/month. Their 'Developer' plan starts at $12/month for 10,000 requests, providing a competitive alternative to Fixer's Basic plan. Open Exchange Rates emphasizes real-time data and a broad range of currency pairs, similar to Fixer.

Currencyapi.com also provides a free tier with 300 requests/month, which is comparable to Fixer. Their 'Starter' plan is priced at $10/month for 10,000 API requests, making it a cost-effective option for similar usage levels. Currencyapi.com highlights features like historical data and conversion endpoints across its paid plans.

A key differentiator often lies in the update frequency of exchange rates, the breadth of currency pairs supported, and the reliability of the data sources. Some providers may offer more frequent updates or more extensive historical data at certain price points. Additionally, API security features, such as mandatory HTTPS, can vary across free and lower-tier plans. For example, while Fixer's Basic plan includes HTTPS, some competitors might offer it only at higher tiers or as an add-on.

For developers and businesses, the choice between Fixer and its alternatives often comes down to a detailed comparison of:

• Request Volume vs. Price: How many requests are included for a given monthly fee?
• Feature Set: Does the plan include historical data, time-series, conversion endpoints, or specific currency sources?
• Security: Is HTTPS encryption included in the desired tier?
• Data Freshness: How often are exchange rates updated?
• Support: What level of customer support is offered at each tier?

While Fixer's pricing is competitive, potential users should perform a direct feature-by-feature comparison with alternatives like ExchangeRate-API, Open Exchange Rates, and Currencyapi.com to determine the best fit for their specific technical and budgetary requirements. The nuances of each service's offering, beyond just the raw request count, can significantly impact the overall value proposition. Factors such as API uptime, data source transparency, and ease of integration can also play a role in the decision-making process, as detailed in general API best practices by Google's API design guidelines on pricing.
