Gateway Weight Class

Gateway Weight Class is the practice of matching API infrastructure tier to the actual traffic and governance load a client will carry, rather than defaulting to enterprise-grade platforms. A single internal CRM sync and a multi-tenant endpoint serving inbound AI agent traffic are different weight classes, and pricing, operational burden, and retainer scope should track that difference. Agencies that size correctly protect margin; agencies that over-provision absorb licensing and maintenance costs the client never agreed to fund. The category spans the full range: Apidog consolidates design and testing for build-phase work, ReadMe covers developer-facing documentation, and Zuplo or API7 handle authentication, rate limiting, and token spend once real traffic arrives. The sizing question is getting harder because agent traffic is arriving whether clients planned for it or not: iOS 27.3 opened agentic Siri to every third-party app, which means client endpoints now face machine callers alongside human ones. Weigh the class before signing the retainer.
