AGL Instrument Cluster API is one of 7 APIs that [Automotive Grade Linux](https://apis.io/providers/automotive-grade-linux/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Instrument Cluster, HMI, C ABI, and Vehicle Signals. The published artifact set on APIs.io includes an API reference and API documentation.

The published interface specification between the Cluster UI in the HMI layer and the IC-Service in the service layer of an AGL instrument cluster. Revision 1.0, officially released 2026-02-04 after four years of drafts. Defined against the C language ABI, with polling and event usage models over pseudo shared memory, enum and macro constant definitions, and a signal retrieval API documented per function. This is an in-process/IPC interface, not an HTTP API - it has no base URL and no callable host, which is why none is recorded.
