Executive summary
Checkout.com - Identity Verification scores 78.1/100: Needs work · Grade C. The weakest pillar is Documentation readiness for AI at 70; the strongest is SDK readiness for AI at 86. We recorded 1056 finding instances: 0 critical, 121 high, 427 medium, and 508 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 Checkout.com - Identity Verification 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.

Address Empty Enumeration and Schema Issues
You must resolve empty enumeration items and undefined schema properties to prevent toolchain failures and integration problems.

Elevated risk · Documentation readiness for AI
AI readers misinterpret API due to documentation gaps
You must provide detailed parameter descriptions to improve understanding and reduce assumptions.
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.

SDKs return incorrect types in responses
We found that the success response lacks a body schema, which may lead to integration issues.
0
fabricated API constructs when a coding assistant was grounded in an AI-ready spec. Ambiguity in the spec is what triggers hallucinated integration code

Agents struggle with operation descriptions
You need to improve the operation's descriptions to provide agents with the necessary content for effective execution.
65%
reduction in token consumption when agent tools are grounded in authoritative API context. Bloated or confusable tools consume up to 3.3× more.
APIMatic Context Plugins research · Series A · June 2026
The evidence numbers come from our controlled research: 6 experiments across 3 models, 6 commercial APIs, and 3 languages. We derive each card's risk status from this API's pillar scores. Full methodology at apimatic.io.
