Executive summary
Your Interrail/Eurail Distribution Platform API scores 72.9 out of 100, reflecting a need for improvement. Standards compliance is mostly ready at 81.6, while documentation readiness for AI shows significant gaps at 59.3. SDK readiness for AI stands at 84, but MCP readiness also reveals significant gaps at 62.4. To address these issues, prioritize improving documentation readiness to enable AI-assisted builds and support autonomous agents effectively.

About this report. We evaluated the Interrail/Eurail Distribution Platform API 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.

AI readers misinterpret API due to gaps
The Parameter Object lacks essential descriptions, leading to incorrect assumptions and degraded functionality.

of developers name missing or unclear documentation as the top reason they abandon an API. AI readers are stricter: what a human would ask about, an AI assumes.

MCP Tools Cannot Execute API Safely
Autonomous agents cannot select or call the API due to missing operation identifiers and unclear operation descriptions, risking execution errors.
65%
reduction in token consumption when agent tools are grounded in authoritative API context. Bloated or confusable tools consume up to 3.3× more.
