Executive summary
Your Agentcard API scored 81.5 out of 100, reflecting a mostly ready status. The API meets standards compliance well at 89.2 but shows weaknesses in documentation readiness for AI at 70.4 and SDK readiness for AI at 79.8. With 14 high findings among 35 rule groups and 833 instances, the API has gaps for AI-assisted builds and is partially ready for autonomous agents. Addressing the documentation and SDK readiness will significantly improve your API's performance.

About this report. We evaluated the Agentcard 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.

Address Empty Enumeration Items and References
We found empty enumeration items and undefined schema properties, which may disrupt SDK generation and downstream integrations.

Clarify API Operations and Error Responses
You should refine the naming of operations and standardize error response formats to improve agent execution and reduce confusion.
65%
reduction in token consumption when agent tools are grounded in authoritative API context. Bloated or confusable tools consume up to 3.3× more.

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.
