WSO2 API Platform

WSO2 API Platform is an open source, unified control plane for managing APIs, AI, and event-driven traffic across cloud, hybrid, and on-prem environments. It enables organizations to design, secure, govern, and productize APIs while scaling agentic and LLM-based workloads with built-in governance and security controls. Teams use WSO2 to prepare APIs for AI agents with auto-generated MCP servers, centrally manage outbound LLM traffic, and gain full visibility into API and AI usage, performance, and cost. The platform supports bi-directional AI governance, covering both inbound agent-to-tool traffic via MCP and outbound app-to-LLM traffic from one control plane. Unlike traditional API management tools, WSO2 API Platform supports both human and agentic consumers from a single platform. It manages APIs across WSO2 and third-party gateways, including Kong, AWS, Azure, Envoy, and Apigee, with federated policy enforcement from a single control plane. Built-in monetization (powered by Moesif) lets teams meter, bill, and productize API calls and LLM token usage through connectors for Stripe, Zuora, Chargebee, and more. Key capabilities include: ➡️ Full lifecycle API management with MCP Gateway (auto-generates MCP servers from ➡️ OpenAPI specs) and LLM Gateway (routing, semantic caching, guardrails, PII masking, and token cost control). ➡️ Deep analytics for API and AI usage powered by Moesif. ➡️ Compliance support for HIPAA, PCI-DSS, FedRAMP, GDPR, DORA, SOX, ITAR, and EU AI Act, with integration for Azure Content Safety and AWS Bedrock Guardrails. ➡️ Flexible deployment: SaaS, Kubernetes, hybrid, and self-hosted. ➡️ 100% open source with zero vendor lock-in. WSO2 API Platform helps enterprises modernize their API programs, adopt AI responsibly, and turn APIs and AI services into secure, scalable digital products.
