Executive summary
Zest equity public api API scores 78.8/100: Needs work · Grade C. The weakest pillar is Documentation readiness for AI at 65; the strongest is Standards compliance at 91. We recorded 541 finding instances: 0 critical, 61 high, 208 medium, and 272 low. Gaps 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 Zest equity public api 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
You have 31 instances of duplicate schema titles, which can confuse developers and disrupt downstream integrations. Addressing this will improve clarity and maintain compliance.

AI readers misinterpret API due to gaps
The missing parameter object descriptions lead to incorrect assumptions, risking integration failures in the equity domain.
74%
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.

Agents misinterpret API operations and tools
The Zest equity public API lacks clear operation descriptions and usable server URLs, causing execution failures.
65%
reduction in token consumption when agent tools are grounded in authoritative API context. Bloated or confusable tools consume up to 3.3× more.
