Reviewer Notes

Navan has an OpenAPI spec and sandbox environment, which aids discovery and testing, but lacks MCP server support and llms.txt documentation. Account creation requires manual signup with potential identity verification steps, making autonomous agent onboarding impossible. The API supports both OAuth2 and API keys, but the platform requires a credit card and company setup upfront, limiting free tier experimentation. Reliability appears solid for an enterprise platform, though rate limiting details are not prominently documented. Best suited for agents integrated into existing Navan customer environments rather than autonomous discovery and adoption.
