TOOLS AND SERVICES
The COUNTER community has developed several tools and services which you may find useful. If you know of others that we should add, please get in touch with tasha@countermetrics.org.
We also introduced new services in 2026, to help publishers achieve compliance with the Code of Practice.

The Registry
The COUNTER Registry is where you can find information about usage data hosts – the technology groups which provide COUNTER reports – and the platforms or publisher websites that they support.
The Validator
The COUNTER Validator tests JSON and tabular reports against Release 5.1 and Release 5 of the COUNTER Code of Practice. It is also used to test the COUNTER API. The Validator is free to use, and we encourage all report providers to test their reports regularly.
Harvester Tools
Harvester tools make it easier to automatically gather COUNTER reports using the COUNTER API. They’re particularly useful if you need to collect COUNTER reports for a lot of platforms, or for lots of libraries. We’ve listed the tools we’re aware of on this page.
Publisher Services
We offer two services to help publishers with their COUNTER compliance:
- Initial Platform Assessments
- Audit Readiness Checks
