Executive summary
Your API, RIS::Stations, scores 73.5 out of 100, which indicates it needs work. The API shows significant gaps in standards compliance and documentation readiness for AI, with scores of 69.7 and 66.5, respectively. While the SDK readiness for AI stands strong at 89.4, the MCP readiness requires attention with a score of 70.4. To improve your API's performance, prioritize addressing the documentation gaps.

About this report. We evaluated the RIS::Stations specification against thousands of deterministic rules we have refined over twelve years of building API tooling, supplemented by AI-based analysis. Every finding is reproducible from the spec itself, scored consistently, and paired with a concrete fix.
What's at stake
Residual risks to monitor
No active failures, but elevated risks remain. Continued improvement will bring these into the managed band.

Confusable Operations Impact API Execution
The autonomous agents misidentify two operations, which may lead to incorrect API calls and degraded performance in the stations domain.
65%
reduction in token consumption when agent tools are grounded in authoritative API context. Bloated or confusable tools consume up to 3.3× more.
