REST API & SDKs

OpenMeter exposes a REST API for integrations:

Cloud API

Open Source API

API v3

API v3 is a rewrite of the OpenMeter API with AIP (API Improvement Proposal) standardization. It provides a cleaner, more consistent design for metering, billing, and related resources.

Work in progress

API v3 is product ready, but incomplete. Some functionalities available in the Cloud and Open Source APIs are not yet available in v3. We are iterating on the spec and adding capabilities over time.


Currently, we provide pre-built client SDKs for:

Node.jsPythonGo

In cases where no specific SDK is available for your preferred programming language, you can utilize the OpenAPI Definitions. Please raise a GitHub issue in our repository to request SDK support in other languages.
