Coval

Coval is a simulation and evaluation platform for AI voice and chat agents. Inspired by autonomous-vehicle testing, it simulates end customers across realistic scenarios, personas, accents, and background noise, then scores agent behavior with built-in and custom metrics. The REST API manages agents, test sets and test cases, personas, metrics, simulation runs, and production conversations.

Coval publishes 12 APIs on the APIs.io network, including Agents API, Conversations API, Metrics API, and 9 more. Tagged areas include AI, Agents, Voice AI, Simulation, and Evaluation.

Coval’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.
