# Availability and changes

Check the current beta’s limits before designing a production dependency.

## Current API reference

The linked reference and downloadable OpenAPI document identify their contract version. The beta includes site discovery, movement and load operations, evidence upload initiation/completion, and webhook endpoint records. Endpoint registration alone does not establish working event delivery.

## Complete workflow availability

Self-service sandbox provisioning, reliable outbound event delivery, complete review-result reads, upload renewal, jobs, and incremental feeds are not offered through this hub. The TypeScript client, Python client, read-only diagnostics CLI, and 17-operation Postman/portable-skill integration kit archives are available separately. Do not depend on planned endpoints or interpret an endpoint record as a delivered webhook.

Existing /api/v1, /sites, nxapi_ credentials, and externalId are compatibility constraints. Keep your integration on its documented contract until a published migration explains any change.

## Access and release policy

API access follows your organisation’s existing arrangements. An owner or admin manages credentials. These public guides do not grant additional entitlements or promise a service-level agreement.

Versioned release notes and migration instructions will accompany changes as they become available. Contact Nexus with your use case if the current contract does not cover it.
