Interactive public research. Expand an operation to inspect parameters and responses. “Try it out” sends a real request; registration signals are not availability guarantees. Credentials are not persisted. Local REST routes are source-audited; external services use their live published definitions (their implementation source is not part of this project). MCP transports are documented for compatible clients, not raw Swagger execution. Renderer assets load from jsDelivr; specifications load from the selected service.
