API documentation drifts away from the running service, so consumers integrate against a contract nobody keeps.

Agents can design endpoints, write and run test suites, manage mock servers and publish documentation, always under the permissions of the connected Routebase account.
Guide developers from setup through a verified, policy-aware, audited Alter API call.
