LangWatch Scenarios API is one of 20 APIs that LangWatch publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

This API exposes 1 machine-runnable capability that can be deployed as REST, MCP, or Agent Skill surfaces via Naftiko.

Tagged areas include Scenarios, Agent Testing, and Simulations. The published artifact set on APIs.io includes API documentation, an OpenAPI specification, and 1 Naftiko capability spec.
