The command center for your APIs

Central, searchable catalog

Understand what APIs and services exist, how they're connected, how well they're working, and who owns them. No more guessing. Just clear, straightforward answers.

Service auto-discovery

Automatically detects APIs from connected repositories and gateways so your catalog reflects what services exist in your organization.

Governance and health scorecards

Apply API governance rules, get real-time visibility and alerts, and block pipelines when rules fail. Check health scores for every service across runtime health, test quality, and spec conformance, then build custom scorecards for your standards.

Get clear oversight of every service with Agent Mode

Stay on top of your entire API landscape without digging through dashboards. Ask Agent Mode which services failed CI/CD tests, returned errors, or have a low health score. Let Agent Mode diagnose the issue, suggest fixes, and raise health scores.
