About

Seams is an API gateway for AI products that meters and caps spend in real time while responses are still streaming, then reconciles to the cent. It lets developers alias model names, route calls across providers, mint per-user API keys, and give customers a branded portal showing usage and remaining balance.

What it does

According to its homepage, Seams sits between an AI product and its model providers: it reserves funds before a request leaves, rechecks the total while a reply is still arriving, and finalizes the charge once it ends. A hosted page lets an app's users see their own usage.

Stated on the product site

Provider key requirement
Customers connect using their own existing model provider API key rather than one issued by the service
Customer portal hosting
Provides a white labeled web portal hosted on a per application subdomain, under the customer's own brand
Billing and merchant relationship
States it is not the merchant of record; the customer keeps the legal billing relationship with its own end users
