Showing 0 of 0 tools
API gateways sit between applications and the services they call, routing, securing, monitoring and controlling traffic. AI and MCP gateways add model routing, cost tracking, rate limits and policy enforcement for AI traffic.
Choosing a gateway
Compare supported protocols (REST, LLM APIs, MCP), authentication, rate limiting, caching, logging and observability, plugin systems, performance and deployment options.
Governing AI traffic
Use the gateway to keep API keys out of apps, set budgets per team, log prompts and responses where policy allows and block requests that break your rules.
