Executive Summary
Vercel has released its Custom Reporting API for AI Gateway, now available in beta for Pro and Enterprise customers. This new API provides programmatic access to consolidated cost, token usage, and request data across multiple AI providers and models. It addresses the challenge of fragmented usage data by unifying metrics, including traffic from "Bring-Your-Own-Key" (BYOK) users, into a single endpoint. This allows teams to track AI spend with granular detail, such as per-customer or per-feature, enabling more accurate financial management and pricing strategies.

* Availability: The API is currently available in beta for teams on Vercel's Pro and Enterprise plans.
Strategic Importance
