Explore the technical details, data coverage, and real-world use cases so your team can plan a confident rollout.
What is the Coverage API?
The Coverage API is a API that returns nationwide cellular coverage and signal strength data for addresses or coordinates. Use it to power serviceability checks, automate eligibility decisions, and embed reliable coverage insights directly into your applications.
It includes RSRP values in dBm, average dBm in 1/4, 1/2, and 1 mile radii around a location, and coverage percentages in 1/4, 1/2, and 1 mile radii around a location.
It's available for each of the major US carriers, AT&T, T-Mobile, Verizon, Boost Mobile, and UScellular, with smaller regional carriers available upon request.
Sample API
| Property | Description |
|---|---|
| provider | Object containing the provider code and name |
| technology | Object containing the technology code and name |
| signal | Object containing signal strength values in dBm for different coverage areas |
| coverage | Object containing coverage percentages for different distances |
| signal.signal | Signal strength (in dBm) at that location |
| signal.quarterMile | Average signal strength (in dBm) within a quarter-mile radius centered on the location |
| signal.halfMile | Average signal strength (in dBm) within a half-mile radius centered on the location |
| signal.oneMile | Average signal strength (in dBm) within a one-mile radius centered on the location |
| coverage.quarterMile | Percentage of the area covered by the provider's network within a quarter-mile radius |
| coverage.halfMile | Percentage of the area covered by the provider's network within a half-mile radius |
| coverage.oneMile | Percentage of the area covered by the provider's network within a one-mile radius |

Use Cases
Examples of how teams apply the Coverage API in production workflows.
IoT & Device Provisioning Automation
Connected devices require connectivity checks before deployment, whether it's a fleet of sensors, meters, or mobile assets. The Coverage API enables automated connectivity validation at scale, so devices are only deployed where they can reliably communicate.
Fixed Wireless Internet Providers (FWA)
Eliminate failed installs and customer returns by validating the expected service with signal strength data. Plus, identify where the cell network performs best to target your marketing and boost ROI.
Cell Tower & Infrastructure Operators
Identify coverage gaps and multi-tenant opportunities by leveraging our Coverage API. Inform smarter site selection and prioritize high-impact deployments.
Why chose CoverageMap.com?
We provide crowdsourced and data-driven maps and APIs of cellular network coverage and performance. Our mission is to help you and your business understand and compare coverage, speed, and signal quality between the carriers.
Where’s the data from?
All of our signal strength data is sourced from the FCC Broadband Data Collection. Our proprietary data processing pipeline handles discrepancies, inconsistencies, or other quality issues with data from the FCC, ensuring you get the most accurate and reliable coverage information possible.
Frequently Asked Questions
What does the free trial include?
The free trial is for 14 days and includes 50 API calls. The output data can only be used for demo or trial purposes and cannot be used outside of that.
How many locations can I look up in a batch request?
The batch lookup endpoint has a maximum limit of 100 locations per request. If you need to process more than 100 locations, you should split your request into multiple batches.
Can I store and cache the data?
Yes, you may persist, cache, download, and store API responses to your own infrastructure for any period of time during or after your subscription. You receive an indefinite license to use the data following the terms of the license agreement.
Do failed requests count towards my usage?
Each coordinate or address that is successfully processed by the system counts as one location lookup. Locations that are not successfully looked up, potentially due to formatting errors or other factors, do not count towards your monthly total.
How do we ensure data accuracy?
We have a custom data processing pipeline to apply corrections to the FCC data. This includes dealing with inaccuracies and discrepancies, and applying our correction algorithm to normalize the data between carriers.
Can I track my usage?
Yes. You can track your usage in real-time from your dashboard and see usage broken down day-by-day.
What countries are supported?
The Coverage API is only available in the United States.
