Reviewer Notes
Airbase has an API and sandbox environment, but discovery is hindered by lack of MCP server, llms.txt, or dedicated API documentation landing page—agents must navigate the main product site. Account creation requires human involvement (no programmatic signup) and credit card validation. The API exists but is not prominently documented for third-party integration, and pricing requires sales contact, limiting autonomous agent operations. Reliability appears solid for an enterprise platform, but agent-native integration remains immature.
