The command center for your APIs

Postman’s new API Catalog puts you in control. Now you can understand exactly 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 so you can keep every service working as expected.

Marketecture that shows API Catalog pulling from multiple data sources, including Postman CLI, Git, and all Postman artifacts (collections, specs, flows, mocks, monitors, environments, insights)

Workspace Analytics

View performance metrics, error rates, and activity across workspaces.

Endpoint Health Monitoring

Track latency, 400 and 500 error rates, and request volumes for every endpoint.

CI/CD Integration

Monitor GitHub Actions, GitLab CI, and Jenkins pipeline runs with PR-level insights.

Spec Linting

Get conformance summaries with spec quality scores and violations grouped by severity.

System Environments

Classify and filter data by environments, including dev, test, and production.

AI Agent Interface

Execute ad-hoc ClickHouse queries with guardrails for AI-assisted analysis.

Watch API Catalog in action

In this brief demo, see how to use API Catalog to manage, govern, and monitor your APIs and services in Postman.

See all your APIs and services in one central, searchable view

Discover all your APIs and services, filter by tags, and get key information like who owns it, its latency, and whether or not it’s passing in CI/CD.

Central searchable view of all APIs and services in API Catalog.

Maintain high-quality testing standards for your APIs and services

Monitor CI/CD pipeline performance, including the total runs, pass rate, and response time for every endpoint, ensuring they meet your testing standards. Seamlessly switch between dev, test, and production environments.
