ATA API Governance
ATA API Governance centralizes API ownership, specifications, compliance, lifecycle management and dependencies across teams. Its inventory records APIs by endpoint, method, version, exposure type, owning team and deployment environment. Lifecycle tracking runs from draft through deprecated and supports multiple versions. A visual dependency tree connects API owners with consumer teams, projects and services to help identify change impacts. Teams can set custom rules for OpenAPI structure, methods, naming, headers and security standards, with real-time feedback on violations. Reusable schemas flag mismatches, while a dashboard reports common security protocols, potential PII exposure and APIs missing required schemas. Ask AI answers questions about projects, APIs, governance rules, schema use and versions. ATA offers web, desktop and Linux options, an npm command-line package, local and server agents, and a browser extension. Free access includes 30 API Governance endpoints; paid tiers increase limits, while Enterprise limits are custom. ATA states its services are not designed for HIPAA, FISMA or GLBA compliance.
