2026 AI API Relay Selection and Pitfall-Avoidance Guide: Saying Goodbye to the sub2api Ban Wave and Model Swapping, and Running APIs Reliably in Produ
In 2026, the large-model API relay market experienced large-scale risk-control account bans targeting sub2api personal subscription resale, and independent research revealed that nearly half of non-compliant endpoints engage in model swapping and downgrading. This article provides developers and technical leads with a production-grade AI API relay selection and integration guide across four dimensions: compute and channel provenance, original-model verification, deterministic flow control, and zero-log and billing compliance.
