Key Updates
The Custom Reporting API lets teams break down AI Gateway traffic by model, provider, user ID, custom tag, and credential type. Vercel says the endpoint works across BYOK and system credentials, so teams can consolidate spend data in one place. The company also includes an example of a platform that saved over $80K by replacing a separate proxy layer.
What Developers Need to Know
Unified reporting makes it easier to attribute inference costs to features, customers, or pricing tiers, which is essential for margin control. It also reduces the need for extra cost-tracking infrastructure and manual spreadsheet reconciliation. For teams running multi-model AI products, this can simplify both observability and financial planning.
How to use it or Next Steps
Teams should start tagging requests consistently with user IDs and feature labels so the reporting data is useful from day one. Then connect the reporting API to internal dashboards or billing pipelines to track real unit economics. If you are already on AI Gateway, this is one of the first features worth piloting.
