V2X Information Service

Scope

Talaia is the open V2X Information Service operated by SkyV2X in implementation of ETSI GS MEC 030 V3.2.1.

It is a testbed. Endpoints under /vis/v2/ are hittable without an SDK, authentication or client library. Eight V2XIS resources, RFC 7807 ProblemDetails on every error, conformance audited against ETSI MEC 032-3.

Production use is out of scope. Integrators needing a hardened deployment should request a signed, gated instance.

Surface

The V2XIS exposes eight resources under one API root. Three queries for radio access provisioning, two operations on the subscription registry, three tasks for predicted QoS, distribution server discovery and message publication. The resource map is enumerated, with curl examples, in section 3 — Surface [3.1]…[3.4].

Operation

Talaia publishes its operational state and conformance verdict live. Both are also exposed as JSON under the API.

Versioning

Talaia follows SemVer. Pre-1.0 may shift the endpoint surface as the implementation closes the conformance suite. The spec compliance declared under /vis/v2/capabilities is the binding contract between releases.

Revision history is maintained in Annex B [B].
