Open Topo Data Pricing: Tiers, Costs, & Comparisons (2026)

Pricing overview

Open Topo Data provides access to global elevation and geocoding data through a tiered pricing structure, balancing free access for low-volume usage with scalable options for higher demand. The service is built on open-source datasets like OpenStreetMap and Open-Elevation, which contributes to its cost-effective approach to geospatial data provision. The pricing model primarily revolves around the number of API requests made, offering a predictable cost structure for developers and organizations requiring elevation, geocoding, or reverse geocoding capabilities.

The core offering includes access to various geospatial data endpoints, such as retrieving elevation data for specific coordinates or converting addresses into geographic coordinates. The pricing structure is designed to be transparent, with clear limits defined for each tier. This allows users to estimate their monthly expenses based on their anticipated API call volume, whether for hobbyist projects or commercial applications. The affordability of Open Topo Data makes it a suitable option for projects prioritizing budget constraints while needing reliable geospatial services.

Plans and tiers

Open Topo Data organizes its pricing into distinct plans, each offering a specific number of API requests per month. These tiers are structured to accommodate a range of usage patterns, from casual individual use to more intensive commercial deployments. The key differentiator between plans is the monthly request allowance, with higher tiers providing significantly more requests at a proportionally lower per-request cost.

The service offers a free tier, followed by several paid subscription levels. Each paid tier provides a fixed monthly request quota for a set price. Exceeding these quotas typically results in additional charges, which are clearly outlined on the official Open Topo Data pricing page. This allows users to scale their usage without unexpected cost spikes, provided they monitor their consumption.

Below is a summary of the available plans and their key characteristics:

The pricing model is designed to be straightforward, avoiding complex credit systems or variable pricing based on data volume. Instead, it focuses on the number of API calls, making it easier for developers to forecast costs.

Free tier and limits

Open Topo Data provides a robust free tier designed to support initial development, small-scale personal projects, and evaluation of the service. This free tier allows for up to 1,000 API requests per day. This daily limit applies across all available API endpoints, including global elevation data, global geocoding, and reverse geocoding services. The free tier is an essential component of Open Topo Data's offering, enabling widespread adoption and testing without an initial financial commitment.

The 1,000 requests per day translate to approximately 30,000 requests over a typical 30-day month. This volume is often sufficient for:

• Prototyping new applications that require geocoding or elevation data.
• Educational projects and academic research.
• Personal mapping applications or tools with limited user bases.
• Testing the integration of Open Topo Data APIs into existing systems.

While the free tier is generous, it's important for users to monitor their usage to ensure they stay within the daily limit. Exceeding the free tier limit will typically result in requests being throttled or rejected until the next 24-hour cycle begins. For sustained usage beyond these limits, upgrading to one of the paid subscription plans becomes necessary. The availability of a free tier aligns with the open-source ethos of the underlying data, making geospatial data accessible to a broader audience, as seen with similar open-source data initiatives like OpenStreetMap's community-driven mapping.

Real-world cost examples

Understanding the practical costs of using Open Topo Data involves considering typical application usage patterns. The per-request cost decreases as the volume of requests increases through higher-tier subscriptions. Here are several scenarios illustrating potential monthly costs:

• Scenario 1: Hobbyist Project (e.g., personal travel planner)

  A hobbyist developing a personal travel planner might make an average of 500 geocoding requests per day to convert addresses to coordinates for route planning. This totals approximately 15,000 requests per month (500 requests/day * 30 days). This level of usage remains well within the free tier's daily limit of 1,000 requests, resulting in a $0 monthly cost.

• Scenario 2: Small Business Website (e.g., local delivery service)

  A small local delivery service website might process around 800 geocoding requests daily for order processing and delivery route optimization. This amounts to approximately 24,000 requests per month. While close to the free tier's monthly equivalent, it might slightly exceed the daily limit on some busier days. To ensure consistent service and room for growth, this business would likely opt for the Basic plan at $10/month, which provides 25,000 requests per month.

• Scenario 3: Mid-sized Web Application (e.g., real estate listing site)

  A real estate listing website could perform 2,500 geocoding and reverse geocoding requests daily for new property listings and user searches. This accumulates to approximately 75,000 requests per month. This usage level would necessitate the Standard plan at $25/month, offering 100,000 requests per month, providing a comfortable buffer.

• Scenario 4: Data Analysis Platform (e.g., environmental research)

  An environmental research platform might perform batch elevation data requests for large datasets, totaling 7,000 requests per day. This usage results in around 210,000 requests per month. For this volume, the platform would select the Pro plan at $50/month, which includes 250,000 requests monthly.

• Scenario 5: High-volume Commercial Service (e.g., logistics platform)

  A logistics platform handling thousands of shipments daily could generate 15,000+ geocoding and elevation requests per day. This translates to 450,000+ requests per month. At this scale, the platform would require a custom Enterprise plan. The cost would be negotiated directly with Open Topo Data, but it would likely offer a more favorable per-request rate than the standard Pro plan, reflecting the high volume.

These examples illustrate how usage patterns directly influence the most suitable pricing tier and overall monthly expenditure. The tiered model allows users to select a plan that closely matches their anticipated consumption, minimizing wasted capacity while avoiding overage charges.

How the pricing compares

Open Topo Data's pricing strategy positions it as a cost-effective alternative, particularly for projects that prioritize budget and open-source data. When compared to major commercial geospatial API providers, Open Topo Data often presents a more economical option, especially at lower and mid-range usage volumes. This is largely due to its foundation on open-source datasets, which reduces the underlying data acquisition costs compared to services that rely on proprietary data sources.

Here's a comparison with some notable alternatives:

• OpenCage: OpenCage also offers a free tier and various paid plans. Its free tier provides 2,500 requests per day, which is more generous than Open Topo Data's 1,000 requests per day. Paid plans for OpenCage start at $50/month for 75,000 requests. While OpenCage's free tier is larger, Open Topo Data's paid Basic plan at $10/month for 25,000 requests can be more cost-effective for users who slightly exceed Open Topo Data's free limit but don't need OpenCage's higher free allowance. For example, a project needing 20,000 requests per month would pay $10 with Open Topo Data versus $50 with OpenCage if they exceed 2,500 requests daily on OpenCage's free tier. More details on OpenCage's plans can be found on their OpenCage pricing page.
• Mapbox: Mapbox offers a free tier with 50,000 requests per month for its Geocoding API, exceeding Open Topo Data's free allowance. However, Mapbox's pricing model is more granular and can become more complex for higher volumes, with per-request costs varying based on the specific service (e.g., forward geocoding, reverse geocoding, batch geocoding). For instance, after the free tier, Mapbox's Geocoding API typically costs $5 per 1,000 requests. This means 25,000 requests would cost $125, significantly higher than Open Topo Data's $10 Basic plan for the same volume. Mapbox's comprehensive suite of mapping tools and data visualization capabilities often justifies its higher price point for applications requiring more than just geocoding or elevation data. Developers can review Mapbox's detailed pricing on their Mapbox Geocoding API pricing documentation.
• Google Maps Platform: Google Maps Platform offers a free tier with $200 in monthly credits, which can cover a substantial number of requests across its various APIs. For example, the Geocoding API costs $5 per 1,000 requests after the free credits are exhausted. This places Google Maps Platform at a similar per-request cost to Mapbox for geocoding. While Google's platform provides extensive global coverage, highly detailed data, and a wide array of services (e.g., Places API, Directions API), its costs can rapidly escalate for high-volume usage. For 25,000 requests, after free credits, the cost would be $125. Open Topo Data remains a more economical choice for applications solely focused on geocoding and elevation without needing the broader ecosystem of Google Maps Platform. Comprehensive pricing details are available on the Google Maps Platform pricing guide.

Overall, Open Topo Data stands out for its simplicity and affordability, especially for developers and organizations leveraging open-source data principles. While its free tier might be smaller than some competitors, its paid tiers offer a competitive price point for dedicated geocoding and elevation services, making it a strong contender for budget-conscious projects.
