Score: 6.3/10 (Innovation: 7, Technical: 5, Documentation: 6, Utility: 7)

Postagent is a CLI tool designed to let AI agents discover and interact with thousands of APIs using a familiar Postman/cURL-like interface. It's interesting because it abstracts API authentication and usage patterns for LLMs, keeping credentials out of the agent's context while enabling complex multi-service workflows.

Target audience: backend devs, devops, ai engineers
