Title: Let's build an agent-ready API from scratch Publication: Ready, Set, Cloud! Author: Allen Helton Published: May 07, 2025 URL: https://www.readysetcloud.io/talks/lets-build-an-agent-ready-api-from-scratch/ Andres Moreno and I design an API for both humans and agents, using Postman Spec Hub to go spec-first and show how a public API evolves into something MCP-ready. #### Description Andres Moreno and I are back building APIs the way the future demands: for machines, not just humans. In this session we design an API meant for traditional integrations and autonomous AI agents, using Postman Spec Hub to show a spec-first approach. We cover why agent-first API design is different, how to build a spec that is actually usable, how to evolve a public API into an MCP-ready server, and why your next user probably will not be human.
