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
Not stated on the site
