Executive summary
Your Test API for payments scores 85.4 out of 100, demonstrating strong compliance with standards and SDK readiness at 99.6. However, documentation readiness at 77 and MCP readiness at 60 reveal significant gaps that hinder performance. While the API is ready for AI-assisted builds, it fails to support autonomous agent calls. Prioritizing improvements in documentation and MCP readiness will be essential for achieving full operational capability.

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 Test 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.

Residual risks to monitor
No active failures, but elevated risks remain. Continued improvement will bring these into the managed band.
