API v1 Deprecation Notice: Migrate to v2
February 7, 2026 · Vanguard Communications
Action Required: Our legacy REST API v1 will be sunset on June 30, 2026. All API consumers must migrate to v2 before this date.
What's Changing
API v1 at v1-api.j0n-harr150n.com was our first public API, built in 2022. While it's still functional, it lacks modern security features like rate limiting, proper input validation, and fine-grained authorization controls.
The v2 API includes improved authentication, pagination, and comprehensive input validation. Migration guides are available in the API documentation.
