Executive summary
Your AI API scores an impressive 86.2 out of 100, demonstrating strong compliance with standards and excellent SDK readiness. However, documentation readiness shows significant gaps at 69.8, and MCP readiness requires attention with a score of 77.1. While the API functions well for AI-assisted builds, it is not prepared for autonomous agent calls. Prioritizing improvements in documentation will be essential for achieving full readiness.

Documentation Readiness for AI
Descriptions that say when to use an operation, examples that pin down every shape: whether an AI can learn the truth of your API from what you publish

Clean types, predictable naming, correct formats: whether production-grade client code can be generated from your spec, by SDK pipelines and AI coding assistants alike

77/100
MCP Readiness
Whether your operations survive being turned into tools: distinct names, descriptions that carry what an agent must know, safe invocation semantics, auth, error recovery, and context budget

About this report. We evaluated the AI 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 Sparse Documentation
You must improve parameter descriptions; missing or short explanations lead AI readers to build on incorrect assumptions about the payments API.

Agents struggle to execute API calls
The AI API lacks a JSON request/response variant, which complicates safe execution and may lead to errors.
