Executive summary
Decart API scores 79.3/100: Needs work · Grade C. The weakest pillar is MCP readiness at 66; the strongest is SDK readiness for AI at 93. We recorded 756 finding instances: 0 critical, 109 high, 263 medium, and 384 low. Functional for AI-assisted builds. Not ready for autonomous agents. Every finding lives in the specification, and the roadmap in this report orders the fixes by impact; resolving them projects the score to 100/100.

About this report. We evaluated the Decart 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.

Duplicate schema titles cause confusion
We found 85 instances of duplicate schema titles, which can confuse developers and disrupt downstream integrations. Addressing this will improve clarity in the API specification.

AI readers misinterpret API details
You must provide detailed descriptions for all parameters to ensure accurate understanding and usage.

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.

We found some instances of AI-written code using guessed formats, which may require manual adjustments.

Elevated risk · MCP readiness
Agents misidentify operations and URLs
The Decart API's confusing operation names and missing server URLs prevent agents from executing tasks safely and effectively.
65%
reduction in token consumption when agent tools are grounded in authoritative API context. Bloated or confusable tools consume up to 3.3× more.
