Reviewer Notes
Fider has a REST API and OpenAPI documentation, but lacks MCP server and llms.txt discovery mechanisms, making initial agent discovery harder. Account creation requires human interaction (email verification), blocking autonomous signup. The API is moderately structured with good documentation, though agent tooling could be stronger with better error messages and pagination clarity. Being open-source with self-hosting options provides sandbox availability, and the free tier supports agent experimentation.
